In 1906, we spent $650,000,000 inbuilding operations and the total cost of our fires was $500,000,-000 and 6,000 human lives.

The Norfolk & Western Railway has recently designed a 50-ton steel gondola car, 300 of which are to be built at its Roanokeshops. Except for a few minor changes these cars will be simi-lar to the sample car that has already been built, and which isshown in the accompanying drawings. While the sample carwas under construction four drop doors were added, so as toallow for a greater discharge opening. To do this the locationof the brake cylinder was changed slightly to admit of twodoors being placed on that side of the car, while the additional plati 5/16 in. thick.
