 improvement on the old design and there arc many 

 machines of the old design outstanding, the ob-

 effort should be made to keep these changes down 

 to those which are absolutely necessary, or which 

 constitute so distinct an improvement as to ju- 

 the expense of making the change and of possihlv 

 obsoleting considerable material.

 value to storage warehouses, or they may possibly
