As may be inferred from the circumstance that the 
author has, in the above list, occasionally indicated his 
preference for the particular "make," colors of the same 
name vary in tone or quality according to the manufac-

Schoenfeld respectively are conspicuously different, being 
equally useful, however. It is quite likely that the wares 
of each manufacturer may vary to a greater or less extent,
