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,
