It may be disconnected from the permanent pip-ing and sent to the mechanical headquarters at the approachof warm weather for repairs and storage until again neededin the fall. The boiler is supported on the car with the firebox project-ing through a hole in the floor, the ash pan being below theline of the sills. One end of the car is partitioned off for coalsupply, and temporary water pipes are laid and protectedagainst freezing. The boiler is fed by injectors and the steamis led through the passenger yards by underground pipes forheating the cars. The location is chosen so that it will not lienecessary to move the steam heating car duiing the entire. Steam Heat Car for Passenger YardsHAND VS. PNEUMATIC RIVETING. In our November number a comparison was made betweenhand and pneumatic hammer riveting on a locomotive firebox,showing the marked saving in cost by the latter method. Wehave further figures on the same subject comparing the costof driving b-in. rivets per day of 10 hours by hand and perday of 8 hours by the long-stroke riveting hammer. The figuresare arranged for comparison as follows:Hand Driven. 2 Strikers at $3 each $ 1 Holder-on at $ 1 Heater at $ Total $ Average number of rivets driven, 375. at $ $ each Hammer Driven. 1 Machine operator at $ $ 1 Holder-on at $ 1 Heater at $ l/12th salary of engineer, 8 hrs. at 25c 1666 l/12th salary of fireman, 8 hrs. at IT^c 1166 l/12th cost of fuel at $ per day 2080 Total $ Average number of rivets driven, 780, at $ each Saving per rivet drive» $ each Saving
