H. NESS — VARIATION IN INDIAN CORN.

of May and early part of June. In Table II., it is shown that the tem- 
perature of April at College Station corresponds somewhat to that of 
June at Ithaca, the mean being about 6° higher ait College Station, 
while the rainfall was 1.97 inches higher at Ithaca. For May and 
July, the months during which the corn made the most growth both at 
College Station and at Ithaca, the mean temperature will be found to be 
only 2 . 20 ° F. higher at College Station than at Ithaca. From this time 
on, we find that the months corresponding in the growth of the corn 
become more and more different in the temperature, the mean tempera- 
ture becoming constantly higher at College Station and lower at Ithaca. 
The following are the differences of the mean temperature between 
the corresponding months: 
April- June, 5.5° F. 
May- July, 2 . 2 ° F. 
June- August, 14.1° F. 
July-September, 19.6° F. 
Bearing these figures in mind, it seems somewhat paradoxical that the 
time from planting to maturity,, as shown in Table I., is, for most 
varieties, a little longer at (Allege Station than at Ithaca. This time 
would have been much more prolonged at College Station if the tempera- 
ture of July had been lower, but it rose to such a degree, even in the 
latter part of June, that no normal ripening could take place; and after 
the 10th of July the corn was literally killed by the heat. 
Another striking difference between the corn here and in Flew York 
was that the stalks of many varieties (Minnesota, Large Excelsior, 
Crosby, etc.,) produced short branches which ended in a cluster of three 
or four ears, all except the terminal one of which were abortive. These 
branches were generally larger when they arose from the lowest joint 
and occurred often as suckers from the stool, or collar, of the root. A 
stalk would sometimes have several of these branches arising either as 
suckers or from the lower joints. 
Before leaving for Yew York on June 30th, thirty stalks of each row, 
or variety, were marked for harvesting and additional notes to be taken 
during my absence; but as our gardener became too busy with his own 
duties, he was able to render account of only one average stalk from each 
thirty. As many stalks had been blown over, and the ears scattered on 
the ground, when I returned, I can give only an approximate average of 
the yield per stalk. 
From Table I. it will also be noticed that in spite of the fact that both 
the stalks and the leaves were smaller at College Station, the ears were,* 
on an average, larger. Uniformly wrinkled kernels, as in the seed, did 
not occur in any variety at College Station, since in every variety ears
