to care for potatoes that have been touched with frost in the ground. 
The first ten days after the storing, the frozen ones cannot be de¬ 
tected nor sorted out with speed. Frosted potatoes can be told at 
any time by thumbing the nose of every potato. After the third 
week they are likely to be semi-liquid rots and to smear the mass 
past remedy. 
Good Light .—Good light 
is required and cannot be 
counted upon from open 
doors or windows at the 
right time because of the 
likelihood of storm and cold. 
Gasoline mantle, acetylene, 
or electric light is sometimes 
available. Some cellars in 
the Greeley district, includ¬ 
ing the new one at the col¬ 
lege, have facilities for sky¬ 
lights in cold weather. Day¬ 
light is the best and none 
too good for the work of 
sorting out the rots. Frosted 
potatoes, like balky horses, 
are bad property. Never buy 
them. We all have enough 
of our own. 
Sorting from Pits .—This 
practice always is dangerous, 
because some years there is 
no weather that allows the 
pits to be opened before the 
long steady cold spells. Most 
seasons this is a very good 
way to handle frosted po¬ 
tatoes for storing or selling 
in November or December. 
„ ^ The man who stores frosted 
shoves-” potatoes and does not sort, 
deserves scant sympathy. 
POTATO DISEASES. 
Diseases Differ from Those of the East .—Work done in the 
East on this subject is of comparatively little value to Colorado’ 
potato growers. Every station in the eastern potato growing states 
has put out from one to a dozen studies on this subject. Nearly
