varieties presenting such marked differences 
should occur may at first seem remarkable. 
But it must be remembered, as Dr, Thurber 
remarked in answer to a letter of inquiry by 
the writer of this, that tbts plant has been iu 
cultivation for untold acres In Africa and 
Southern Asia. In all these centuries it has

broken into apparently as many varieties as 
Indian Corn. Just as in corn, these sorts may 
be grouped by some striking peculiarity. We 
have Dent, Flint, Sweet and Pop-corn groups, 
each with many varieties, and so it is with 
sorghum. We have Broom-corn, Sugar- 
sorghums or Doura or “ Millet,” each, espe-

cept, pernapa, Peruvian gqano, offers so favor¬ 
able a relation between estimated trade value 
and market, price. The trade valuation is 
based on the proportion of nitrogen and phos- 
phoric acid in the fertilizer, and the average 
cost of these substances in fertilizers gener¬ 
ally, in equally soluble and assimilable forms, 
and also on the degree of fineness of the bone- 
meal ; the finer it is, the more rapidly its con¬ 
stituents will become available iu the soil, and 
the quicker will be the return for the capital 
Invested iu tbe manure. 
The following table exhibits some of the 
genera] average results that have been obtained 
in these analyses.

rue average quality of this fertilizer, as la 
shown in the above table, vanes considerably 
in different years as well as in different locali¬ 
ties. It does not appear to be a favorite 
manure at the South, which, considering the 
comparatively poor quality of the article aa 
offered there, la quite natural. The average 
result of the analyses made at the Connecticut 
Experiment Station in 1S7S, is reduced by the 
comparatively large number of poor samples 
received at the Station that year. Dp to the 
date of this writing, December 10, the average 
results obtained this year Indicate a marked 
general Improvement in quality.
