Industrial Materials A LTHOUGH seaweed is, Now Made From r-lemployed as food in Japan
Seaweed and northern Europe, and even in this country, it is now being used for other products, such as chemicals, fertilizers, glues and agar for bacteriology. Recent patents show that it is now also forming a raw material for the manufacture of plastics, Rubberoid and a transparent film used for packaging purposes.
Good Example of A N instance of the way in Efficiency in the rThwhich the motor industry Motor 'ndustry. . has been able to expedite and
cheapen armament production was given recently by Sir William Rootes. One item in the construction of aircraft had cost the aircraft industry 00 to produce. By the time the Rootes Organization had tackled the problem the price was reduced to under 50s. This is an indication of how one industry can learn from another.
Rem.over Almost Becomes Victim of ACONFIDENCE trick to
extract a loan is referred extract a loan is referred to in a letter in "Removals
and Storage." A man of good Appearance asked a remover for a quotation for carrying three loads of furniture. After a full discussion and the settling of dates, the contract was signed, and it was understood that the first van would be at the address on a particular day. • About an hour later the man returned and asked for a local street directory. He searched unsuccessfully through this, saying he was trying to find an old friend, as he had come from home without Much cash, and if he could only find him he could easily borrow all that was required. As the remover had just
booked a £60 order he was inclined to be sympathetic, and the man then suggested a loan of £10, for which the furniture could act as security. The remover, fortunately, said that he had no cash available, and later on wrote to an association friend in the town to which the van was to be sent. The reply came that there was no such address as that given. If this precaution had not been taken he might have lost his £.10 and have sent at least one van on a 100-mile journey. Others in the industry should beware of this and other methods of obtaining easy money.
A Few Points ConMANY modern engines have cerning Sparking-plug IVItheir sparking plugs deeply Maintenance. . . recessed. Consequently, there

spanner to the gland nut, which, however, may often come loose, leaving the body embedded in the cylinder Even if the plug be removed in this way, it will probably be found later that the gland has been badly distorted. The proper tool for the job is the box spanner. Incidentally, when cleaning a plug, such as the Lodge, which can be dismantled, the body should be held lightly in the vice, so that the glana nut can be carefully unscrewed. The insulator should be cleaned with a petrol-soaked rag, or, if necessary, scraped gently with a knife, the latter process being used also for the plug body, whilst the points can be cleaned with a piece of fine emery. When re-assembling, the gland nut should be tightened smoothly and steadily, and the gap setting carefully checked. If it needs adjustment, move only the side point. Any attempt to bend the central electrode may fracture it or damage the insulator. I T has been stated that 66.6 per cent. of the materials, in various states of completion, used in British motor vehicles is controlled by rings, combines and cartels. Considering a private car as a whole, fabricated materials form 41 per cent., steel parts 28 per cent., grey and malleable iron 8 per cent., glass, rubber, copper, zinc and other materials making up the total. • More Rubber Growing THE U.S.A. is growing hevea
