Hence the weight of the flesh proper was . . 6.821 ,, 
The mean of the two trials gives the following percentage results: 
100 lbs. of fresh pumpkins contain in round numbers about 33 Ibs. 
of rind, 8 Ibs. of seeds, &c., and 884 lbs. of flesh proper. 
For the sake of comparison, the amounts of nitrogen contained in 
the flesh proper and in the rind of these new pumpkins were deter- 
mined, and the results were contrasted with those previously obtained 
with the pumpkins of 1876 (see p. 92). To obtain fair samples for 
these analyses, all the rind from both the pumpkins was dried and 
ground to powder; and a number of pieces (eighths) of the flesh proper 
were cut out methodically from different parts of the pumpkins, and 
likewise dried and ground. ‘The results of these new analyses agree 
very closely with those previously obtained in 1876, as will appear 
from the following statement: On the supposition that the materials 
examined had all been dried at 110° C., the amount of nitrogen found 
in the: — Flesh. Rind. 
of the two pumpkins of 1877, was . . . . 1.80% 2.93% 
of one of the pumpkins of 1876, was . . . 1.84 2.98 
of the other pumpkin of 1876, was . . . . 2.20 3.51 
Mean of the estimations of 1876. . . . 2.02 3.25 
Mean of the estimations of 1876 and 1877 . 1.94 3.14 
From all of which it appears that the pumpkins of 1877 are justly 
comparable with those of 1876. We can now, more readily and more 
precisely than was possible before, make use of the analyses given on 
pages 83 and 84, for the discussion -of the empirical practices of our 
farmers in feeding pumpkins. For example, one common method of 
procedure is to feed out pumpkins in the autumn to milch cows kept 
in pastures, as an addition to or re-enforcement of the failing grass. 
Small pains are taken, it is true, to make the pumpkin ration definite 
or precise ; but it is not impossible to gain a general idea of the amount 
of food administered in this form. Let it be assumed, for instance, 
that in the beginning the pumpkins are fed out at the rate of about one 
medium-sized one per day and per cow, and that the quantity is grad- 
ually increased until as many as four such pumpkins are given per 
day and per cow of 800 or 900 Ibs. live weight. Since, as has been
