Directions for sending in plant disease specimens for identifica- 
tions During the growing season numerous specimens of plant 
diseases are mailed to the Agricultural College for identification, ac- 
companied by a request for advice on methods of control. The 
College is willing and glad to render service along this line and in 
order that the most accurate and reliable information can be sup- 
plied we ask that certain important suggestions be carried out in 
preparing the specimens for mailing. Frequently specimens are 
received at the College in such poor condition that it is almost 
impossible to make an accurate determination. If the plant is 
sufficiently small it is w^ell to include roots, stems, leaves, and fruit 
when possible as very often one part of a plant may die as a result 
of an infection on some other part. For example the leaves ‘and 
fruit may die as a result of an organism attacking the roots or stems. 
In such cases if only the leaves and fruit were sent it would be im- 
possible to determine the cause of the injury. 
Many of the specimens received at the College in poor condition 
were no doubt in good condition Avhen mailed but it must be re- 
membered that such mail is often on the, road two or three days 
during which time the specimens become dry and brittle before 
reaching their destination. 
Specimens should be wrapped in several thicknesses of moistened 
newspaper, then covered with several layers of thick wrapping paper 
or inclosed in a pasteboard box. 
Address all specimens to, 
The Colorado Experiment Station 
State Agricultural College, 
Ft. Collins, Colorado.
