German P.O. Motorbuses.
New motorbus lines are announced r Wurtemberg, East Prussia and Bavaria, those in Bavaria being worked by the Post Office, to whose irrowing system of motor-postlines a more-or-less circumstantial reference imias made recently in these columns. The Prussian line will connect up (.; oda p and Ilominton, and is expected to pay tolerably well, as existing arrangements for coping with the growing traffic between these towns are inmlequate.
Fur in Boilers.
I'mte.-..sur Dr. Dmikelberg, of Wiesbaden. has invented a filter for arresting the various salts which tend to forum hoiler-crust. He stipulates, however, that silicic acid, in the form of silicate of potassium, should be added in very small quantities to the water before the latter passes through he filter, which, through the acid': agency, arrests the above-mentioned :milts and transforms them into sibc-u tea: these remain behind in the filter as deposits. Silicate of potassium iosts little. The filtering substances t----nsist mainly af layers of sand and

Berlin's Street-cleansing Department.
In time annual report issue by
Street-clearcsing Department, reference is made to the excellent results obtained from the besprinkling of the city's asphalt and wood-paved road: with oil-emulsion, through the use of which it was possible to withdraw the watercarts from service for several weeks at Si time without the public suffering annoyance from dust, whereas, when no emulsion Was employed, the carts were often out several times a day. Supposing the roads to be sprinkled tirres in the course of the
S ummer, and watered in addition whenever necessary, the cost per square metre, exclusive of the cost of water (in Berlin the cost of water is regulated by the quantity used, not by any form of rent valuation.—En.). worked out at 0.009 mark, while the application of water alone also exclusive of its cost, entailed an expenditure of 0.07 mark per square metre. A solution of chloride of calcium also gave very satisfactory results.

As Trtisel is foiir miles distant, the penny fare cannot be described as exorb i tmint.
