Its efficiency is just as great at theend of one or two hundred feet of hose, as at the end of aten foot section, and it has a very great advantage in the factthat there are no devious and crooked pipes to clog.

As an illustration of the effici-ency to which this machine has been raised it may be said incleaning steel cars, one man and one machine clean an averageof three cars a day, ready for the painters. This work byhand would require forty men, and the sand blast does a betterjob, the sand cleaning where hand tools cannot reach. 196 AMERICAN ENGINEER AND RAILROAD JOURNAL. May, 1911. The same principle involved in the constrnction and operationof the Mott sand blast has been also successfully adopted by thecompany in the application of paint by the spraying idea of the economy in time, labor and material may begained from tests showing that an op
