arise, we would have little difficulty in disposing of the crop to the. 
eastern trade. At present, we are shipping in the open express car 
as far east as central Kansas and Lincoln and Omaha, Nebraska; 
north to Billings, Montana, and south to northern Texas and Ok¬ 
lahoma. 
From this brief statement of the raspberry industry in North¬ 
ern Colorado', it will be seen that any factor or factors which ma¬ 
terially affect the production of berries may mean much to the 
prosperity of the section. An examination of the yields for the 
years 1910-1913, inclusive, as shown by the shipments made by 
one of the largest Fruit Growers' Asosciations, indicates clearly 
that certain agents were operating to bring about a marked de¬ 
crease in production for that period. In 1909, the association men¬ 
tioned handled 13,150 crates, while in 1910, only 1,655. Quite 
naturally, those engaged in the berry business felt considerably 
alarmed over this state of affairs, and at the request of the most 
extensive growers, we have undertaken to study the prevalent 
conditions and to ascertain some of the causes which are contrib¬ 
uting to these failures.
