As our analyses of the third cutting were made on hays, 
as prepared to put in the mow, we have no figures showing 
the amount of moisture lost in curing. 
The average of the eleven samples of first cutting is 
73.14 per cent., which means that every 100 lbs. of alfalfa as 
it stands in the field will give 26.86 pounds of well cured hay 
for the first cutting. An examination of the preceding 
table shows that there is not so great a difference in the 
amount of moisture in the alfalfa at the different stages of 
its growth at which it is cut for hay, or even for soiling, as 
might be supposed. 
The average for the second cutting is some lower than 
for the first, but no very immature samples are included. 
The number of samples is also smaller, i. e., five samples 
with an average of 71.08 per cent, according to which each 
too pounds green crop gives 28.92 pounds of hay at second 
cutting. These results are much more uniform, and indi¬ 
cate less loss on account of moisture than those given by 
others. The average moisture in alfalfa hay, first cutting, 
is 6.03 per cent., the average of 13 samples, lowest, 3-771 
highest, 8.87 ; for the second cutting, 5.94 per cent., the 
average of nine samples, lowest, 4.31 ; highest, 7.25. 
The average water content of green alfalfa, at time of first 
cutting, is 74.76 per cent., and at time of second cutting, 
72.80 per cent. 
Dr. Allen kindly furnished me with the results recorded 
by Dietrich and Koenig as 76 per cent, at beginning bloom; 
also 76 per cent, at full bloom. These are averages, 
the former of results ranging from 72.2 to 82 per 
cent.; the latter of results ranging from 70.0 to 83.1 per cent. 
The New Jersey Report for 1888, gives water for first 
cutting as 79.46 per cent.; for second, 64.37 per cent., 
alfalfa in drills ; 80.61 per cent, for first cutting, 61.69 P er 
cent, for second cutting, when sowed broadcast. The unifor¬ 
mity in our results is probably attributable to our climatic con¬ 
ditions and mode of culture, rather than to differences in 
the soils of New Jersey and Colorado. The New Jersey 
averages show the first cutting to contain more water, or to 
be more succulent than the second ; while the results re¬ 
corded in the Texas Bulletin No. 20, 1892, showthe reverse, i. 
e., for the first cutting, 69.40. per cent., average of four analy¬ 
ses with 62.44 per cent., as the lowest, and 75.65 percent., as 
the highest, and for the second cutting, 76.54 per cent, with 
71.77 per cent, for the lowest and 81.59 per cent, for the 
highest.
