He writes us that he hashad one of his sanders ,in operation on a locomotive since the beginning of theyear. Our illustration, taken from patentNo. 752,598, shows the construction ofapparatus. The interior of the sand boxis provided with a spiral coil of pipewhich passes down near the walls of thebox and terminates in two nozzles orjets which discharge into the sand pipes,marked C2, This pipe leading from thecab, supplies live steam to the sand noz-zles, C4, and facilitates the movement ofthe sand if the pipes should becomeclogged or stopped in any way. A valveand suitable T connection is shown atF, which cuts oflf the flow of sand to theforward driving wheels and forces it, bythe aid of a broad flat jet of steam, topass into the back-up sand pipe. The fundamental idea in this sandcris the use of wet sand. If the sand isnot wet when it is put into the box itis certainly wet when it reaches the use of wet sand, therefore, doesaway with all sorts of sand drying ap-. SAND BOX FOR USING WET SAND, pliances and a patent has been grantedin five countries to the inventor. By reference to the illustration a cir-cular pipe, marked B, can be seen at tlictop of the box. This pipe runs aroundthe wall of the box and is perforated atintervals. Another pipe enters from thebottom, marked D, and this verticalpipe is perforated at its upper end, butis covered over by a cast iron hood, EBoth these pipes are supplied with waterfrom the same source and the operatingvalve is in the cab. The object of thehood, E, is to prevent sand caking onor clogging up the perforations in thewater pipe. When it is desired to sand the trackthe water valve in the cab is opened , hot water is turned on, whichiiows out of the vertical pipe. D, in agood stream and so practically under-mines the sand in the box and washes itinto the sand pipes, and at the sametime water is
