Prior to 1916, 50 per cent of the apple growers visited used a 

 crew of two men and two horses for spraying, while 40 per cent 

 used a crew of three men and two horses. (See Table XVII.) It 

 was found that in each county the 3-man, 2-horse crew sprayed 

 more acres per day than the 2-man, 2-horse crew. More material 

 was applied per acre and per tree with the crew of two men and 

 two horses than with the larger crew, and the labor costs were about 

 the same. Thus ordinarily the 3-man, 2-horse crew is to a consid- 

 erable extent the more economical.
