40 States in which barley is grown, its value per acre is greater 
than that of wheat. The lowest return per acre from barley (in 
Nebraska) is 1/. lis. Id., whereas the return from wheat goes as low 
as 1/. 4s. 9rf., and is less than thirty shillings in seven different 
States. The lowest average yield of barley is 10-4 bushels in 
Alabama. 
Buckwheat is grown in 29 States. The average yield ranges 
from 20 8 bushels in California, to 8-5 bushels in Tennessee, and the 
average value from 3Z. 5s. 4o?. to \l. 3s. Id. in the same States 
respectively. 
Potatoes are universally grown throughout the States. The 
highest average yield per acre is llT'l bushels in Washington, and 
the lowest, 55 bushels in South Carolina. The average value per 
acre ranges from 15^. 17s. 8c?. in Nevada, to 6/. 7s. in Tennessee. 
Tobacco is cultivated in 17 States. Massachusetts stands first, 
both as regards the quantity and value of the crop. The average 
yield per acre is there 1485'4 lb., and its value, 42^. lis. 2d. The 
lowest average yield is 480'8 lb., in North Carolina, and the lowest 
average value is 9/. 4s. 4c?., in Maryland. It is rather curious that 
Virginia, with all its tobacco traditions, stands, with the exception 
of Maryland, lowest on the Kst, both as regards yield and value. 
Cotton is only grown in 1 1 States. Louisiana stands highest, 
with an average yield of 232"7 lb. per acre, worth il. 6s. 9c?., and 
Florida lowest, with a yield of 106-4 lb., worth '21. 6s. Qd. 
Hay is, of course, a universal crop. The yield ranges from 1-39 
tons in California and Oregon, to 0'93 tons in New Hampshire. 
The value, however, bears but little relation to the yield. It is 
highest in Massachusetts, where it makes 3?. 18s. 5c?., although the 
yield barely exceeds a ton, and lowest in Nebraska, where a yield 
of nearly a third of a ton per acre more only makes 1/. Os. \d.

THE SMUT OF ONIONS. 
ly the Annual Report of the Connecticut Arrricultural Experi- 
ment Station for 1889 Dr. R. Thaxter gives a description of this 
fungus, and also the results of experiments made by him with the 
object of finding some means for its prevention. 
The smut of onions (Urocystis Ceptdce, Frost) has only been 
recorded as causing serious disease within comparatively recent years.
