The bottom of dust guard pocket has been made semi-circular, to reduce the cost of box. The angle of lid face hasbeen made the same for all boxes. Various minor, or unim-portant, dimensions have been unified. No changes affectinginterchangeability, or serviceability, have been made. Springs Complaints relating to the unsatisfactory results fromstandard springs have been increasing rapidly. The causes.

The result is that manysprings either break or take a permanent set. The remedy recommended is: (1) To improve the methodof manufacture by better control of heating and temperingfor more uniform results, and to obtain greater uniformityof coiling; (2) to use alloy steel; (3) to grind the ends ofthe springs to present a flat bearin
