Which of the following most accurately describes the problem?

An example of this company's well-known traction-type four-ton steam wagon is staged by Wm. Allchin, Ltd., the well-known maker of Northampton. This machine is a characteristic example of modern steam-wagon praetice, and is fully representative of that class of design in which the engine is located over the loco-type boiler and the final drive is by long single chain to a live back axle. Amongst Allchin features which should be specially examined are the special doublepin-drive back wheels, which are giving excellent results----this obviates the necessity of keying one wheel on the axle, and it. of course, provides for simple and quick removal of one or both wheels.

The Allchin machine is of a type which makes a definiteappeal to many of the users of the class who frequent agricultural shows and meetings, and is, therefore, a particularly appropriate exhibit at the Sni ithfield.

Aveling and Porter (Stand 2).

This old-established Rochester concern is rbpresented by one of its standard three-ton compound steam wagons. The particular example which is staged is a repeat order for Russell's Gravesend Brewery, Ltd. it will be recalled that the latest Avefing and Porter steam wagons, as exhibited at recent Royal Shows, had a number of interesting structural specialities. This was particularly noticeable in respect of their Ackermann steerage, the special disposition of the wheelbase, the particular arrangement for " singling " the cylinders, and the modern design of brakes.

Barford and Perkins (Stand 190).

Heavy road rollers are not admitted to the Smithfield Show, as the powers that be do not consider that they are " sufficiently agricul • tura]." Barford and Perkins, Ltd., the expert roller company of Peterc30 borough, therefore, has had to content itself with the exhibition, at the Agricultural Hall, of one of its A-pattern rollers fitted with Cambridge rims. The machine in question is the subject of one of our illustrations. This is a model, which, like the others produced by this manufacturer, is widely known and very largely used. It is particularly adapted for agricultural purposes, and it can also be suitably employed on golf links, racecourses and cricket grounds. it is made in rolling widths of 5 ft. and 6 ft., and is engined with a motor of 12 h.p. This company, of course, makes rollers of all sizes up to 14 tons.

Burrell (Stand 27).

At the time of our visit to the show, it appeared that, this wellknown maker was being represented on ita stand by a single example of its well-known steam tractor. This machine apparently presents no novel features, but it is an example of high-grade construction which has now, for a number of years past, recommended it to users. The Burrell steam wagon, with its unique double-chain final drive, is not exhibited, but it is a

model about which intending purchasers would do well to inquire, with a view to consideration of its several special features.

Clayton and Shuttleworth (Stand 25).

The exhibit which undoubtedly attracts most attention at the Smithfield Show, from the visitors who are specially interested in heavy-haulage units, is the new three-ton petrol wagon chassis, now exhibited for the first time by this company.

On the whole, no departures have been made from orthodox practice, but the company prides itself on having produced the whole machine, with the qxception of the engine, in its own works, including such processes as frame-pressing, malleable casting and aluminium casting. The design provides for a Dorman engine.

The other exhibit on Stand 25 con tutes, as we have stated elsewhere, as only petrol-driven lorry in the Show. Furthermore, this 3-ton chassis is here exhibited for the first time. The construction is on orthodox lines, bearing evidence of careful attention to detail, whilst the nedessity for providing adequate strength to meet all likely demands has not been overlooked.

The specification covers a. 45 h.p. fourcylinder water-cooled engine, with Claudel-Hobson carburetter, high-tension Jilagntito ignition, thertne-syphon circulation of the cooling water, encibsed„.,valve

gear, etc.„ etc. A cone (Ankh and leatlier-jointed clutch shaft transmit the power to the four-speed-and-reversegearbox. The latter is fitted with change 1-peed on the gate-change principle, and the box has east integral with it the housing for the spherical-ended, tubular part which serves to convey the driving thrust from the rear axle, as well as to re-act against the driving torque.

The whole of the transmission, from the gearbox rearwards, is totally enclosed. The mar axle is worm-driven, of the type in which the worm is above the wheel. It is fall-floating, the load being carried by a doable-banjo forged-steel niain axle, with cast covers above and ii How to form a spher:.Cal Centr.2.. portion. Both brakes are in the rear wheels, side 1 iv side, in separate drums.

One of the well-known Clayton and Shuttleworth five-ton steam wagons is also included in this exhibit, which model is mounted on rubber tires. It corresponds in general practice to the usual traction-type wagons with which we are now all familiar.

Fowler (Stand 24).

While this Leeds house as a rule occupies one of the most prominent positions in all Agricultural shows of importance, the majority of its exhibits are. of types with which we have little concern. Fowler's are very largely interested in the product;on of the heaviest classes of ploughing tackle. This maker, however, nowadays produces something quite at the other end of the scale in the shape cf the Fowler selfcontained motor plough, which embodies many of the same patents as those which cover the Irleryles motor plough itself. An example of this small machine, which is practically identical . with that which was shown at the last

Royal," is staged at Smithfield.

It is two-furrow implement and can, in addition to ploughing, be adapted for harrowing, scuffling and cultivating. It has a castor furrow wheel at the back end to take the weight when clearingthe headlands, and is fitted with a driver's seat. A pulle-y is provided for use when it is dc-sired to utilize the machine for driving a chaff cutter or other implement..

Fodens, Ltd. (Stand 14).

This concern has been, for a long while past, exceptionally busy on. (1-overnment work, but we are pleas,EA to notice that it is repre,;ented by one .of its standard threeton rubber-tired models at the Agricultural Hall. The machine in question is a repeat order for .Atessrs. F. A. Clark and Son, Phoenix Lead Mills, Hammersmith. The type which has now become so

popular with other makers is familiar to the majority of users— the loco boiler, the over-type engine and the single-chain drive to a live axle. Hundreds of Foden wagons continue to do. much of the heavy motor-haulage work in this country, and, in addition, do their share of .aetive service in France

and elsewhere, in the pa.rticulaf!y arduous conditions which preva at the present time. It is appropriate that a. Fod.en should be staged a.t Smithfield. It is representative of what is best in British heavy-motor production. We are frequently receiving good rie,is of their service in Franco.

Garrett (Stand 19).

A steam-wagon display which is always of interest at exhibitions of this sort is that staged by Richard Garrett and Sons, Ltd., the wellknown maker of Leiston. At Smithfield we find an example of the company's three-ton, rubbertired steam wagon, which embodies this maker's well-known superheater system, and, in addition, a five-ton steam tractor, designed to employ saturated steam. This latter machine can be supplied with the Garrett. superheater outfit in the usual way if thought. desirable. All Garrett steamwagon and tractor examples are fitted with the company's patent corrugated firebox, a form of construction which, of course, not only yields increased steaming capacity, but affords additional strength and facility for accommodating distortion due to heating. It will he recalled that the Garrett machines have in the past set up remarkable records for consumption economy, and this specific claim, which is maintained by the company for its productions, should be a particularly valuable asset at the present time for obvious reasons.

Ivel (Stand 13).

One would naturally expect to find typical examples of Ivel maimfacture at any exposition of agricultural implements. The Ivel three-wheel tractor is by now so well known in its general arrangement of mechanism as to need no detailed description oi . the presen occasion. An example of this simple and hard-wearing machine is staged, and it is also interesting to note that one of the small IvelBauche motor hoes is available for inspection.

International Harvester (Stand 33).

Two examples of this company's oil tractors are displayed, one a 10 h.p. and the other a 25 h.p., both of them known as Moguls. The smaller one is of the type which has recently been demonstrated in England and Scotland, and particularly at the recent Stirling Trials. It has a single-cylinder, horizontal slow-running engine, consuming paraffin, it is provided with planetary transmission gear.

Mann (Stand 16).

This Leeds company is staging one of its light steam a.gricultural tractors which apparently is one which has been recently engaged in the series of agricultural trials which has been taking place in the North of England during the past month or two. This particular maclime, we learn, has been sold to Mr. Stanley Steavenson, of Mid c36 dleion St. George, Co. Durham. This machine is of standard type, weighing about 4? tons empty ; it is capable of pulling a fourfurrow plough with the shares set to turn over 7 in. deep in strong

land, or it can handle two binders or loads of from five to six tons on the road. To secure effective weight distribution on the land the wheels are set in such a way as to cover a total width of 4 ft. 8 ins.

Marshall (Stand 12).

This leading concern advises us that it is too busily engaged in thn:. manufacture of war material to hr ii a position to prepare any exhibits of the " traction " class. It is interesting to note that 2000 men el the company's normal 5000 have enlisted in the various branches of the service. Surely this is a record for an engineering firm. Under the circumstances, therefore, it will not surprise our readers to find that this company has. no tractor or agricultural motor staged at the Smithfield Show this year.

Martin (Stand 17).

On this stand, in addition to the usual non-mechanical propelled farming implements, are shown a couple of Martin's patent motor ploughs. It may be remembered that an example of this construction was first exhibited at the Royal Show, Nottingham, in July last. On that occasion we were able to describe it in some detail.

The construction is very little different to the one we saw on that occasion, and the distinctive feature of utilizing the two continuous chain treads, similar to that used on the well-known caterpillar-type tractor, has been retained.

Overtime (Stand 29).

The Overtime Farm Tractor Co., of 127, Minories, stages one of their 24 h.p. agricultural machines. This is fitted with a twin-cylinder water

cooled engine, with automobile type radiator and fan. The transmission is by cone clutch to gearbox giving one speed forward and one reverse. It is capable of hauling a three-furrow plough, or of cultivating seven acres per day.

Petter (Stand 10).

Potter's principal exhibit from a commercial-motor point of view is the semi-Diesel-engined small 10 h.p. agricultural tractor. This has several distinctive features. It is provided with two speeds and reverse gear, and drives by means of worm and wheel to the offside rear wheel only, the nearside wheel run_ fling free. A substantial gilledtube radiator assists in the cooling of circulating water, and this is backed by an ordinary four-bladed automobile-type fan. The steering gear is, we think, unique in the experience of British-vehicle manufacturers, insomuch as it is arranged to be operated by means of a rope, so that the driver sits on the seat at the back and steers it just an though it were a horse. It will be noted that a large wooden arrow, easily visible to the driver, is placed so that he can tell ata glance the position of the front wheel.

I/obey (Stand 23).

The only exhibit on this. stand which is of particular interest to the readers of this journal is the Rebey five-ton rubber-tired steam Wagon.

This company manufactured its first practical steam road vehicle in 1870. Its present Model conforms in most respects to the locoboiler type, which is now so popular and in such, general use all over the country. The boiler has a Belpaire firebox. The engine and transmission arrangements conform to accepted standards. There are many small det-ils, however, in this design which (,ne does not find in similar machines of other makes. We would, for instance, mention the spring-mounted hangers of the hind laminated road springs. We cannot do better, at the moment, than refer our readers and visitors to Smithfield to the excellent steam-wagon catalogue, No. 232, which this company has produced. It is one of the best-produced brochures of its kind we have seen.

Sandusky (Stand 58).

On this stand is staged one of the company's 35 h.p. tractors. It will be remembered that this was one of the machines which competed at the recent trials at. Stirling, N.B. It is one of the larger examples of American multi-cylinder, petrol-engined agricultural machines, and it is obviously capable, under suitable circumstances, of undertaking work sufficient to justify its considerable horse-power.

Saunderson and Mills {Stand 41.

One of this company's range of oil-engined tractors is staged. The company has chosen model " G " to represent it on this occasion. This has a two-cylinder vertical engine set crosswise on the frame, and a three-speed gearbox. The company's method of three-point suspension is embodied. It will be recalled that the Saunderson and Mills tractors are marketed in a range which includes sizes from 50 b.h.p. down to a small 10 h.p. machine.

TAsker (Stand 7).

This company is displaying one of each of its two standard five-ton tractor types. Interest will still be centred, in all probability, on the company's chain-driven model, as this embodies a principle which has not been developed to any extent elsewhere for tractor work. This chain-drive model has extra, long springs. It is claimed that the flexibility of the drive and of the suspension render this one of the easiest-riding tractors which can be purchased. The standard constructional features of the " Little Giant" models are sufficiently well known to render further description here unnecessary.

Wallis and Steevens (Stand 18).

Yet another example of the standard type of steam tractor is that staged by Wallis and Steevens, Ltd. It is a useful alternative for those who are considering the possibility of the purchase of a machine of this type, and it compares favorably with other 5-ton tractors.

W eks (Stand 21).

One of the latest newcomers to the ranks of British-made agricultural motors is that known as the Weeks-Dungey &triplex agricultural tractor, manufactured at Maidstone. It has a Four-cylinder enginewith a three-speed-and-reverse gearbox bolted to the crankcase to form a complete unit. Behind this, conveying the power to the first bevel reduction in a easing above the rear axle, is a leatherjointed propeller shaft. The final drive is by spur pinions gearing with internal-toothed racks in the )F-ai wileels. The wheels of this machine are fitted with rubber tires, which is an unusual feature, mid so shod it can in no way be intended for use on heavy or wet land. The rear wheels, however, are wide enough to allow of spuds of any kind being fitted outside the rubber tires.

Wyles (Stand 67).

Following so closely on the unmistakable able success achieved at the Stirling Trials and elsewhere in the North of England recently, the appearance of the Wyles self-contained motor plough at the Smithfield Show is auspicious, and its recent performances will undoubtedly attract for it a great deal of specific attention. It corresponds in many of its principal features with the Fowler motor plough, which also is manufactured under many of the Wyles patents. The machine which is exhibited. is of the two-furrow type, and has all the latest improvements.

Fastnut (Stand 106).

The Fastnut specialities marketed by Fastaut, Ltd., 115. Newgate Street, EC., are on view on Stand No. 106. The exhibit consists chiefly of an attractive display of -spanners, wrenches, Fastnut washers, and other labour-saving devices. The particular rorality of the accessories manufactured by this concern is well known and needs little praise here.
