Drying by the ordinary method produced, in this case, a loss per acre of 153 Ibs. of albumin, 
50 Ibs. of fat, 59 lbs. of fibre and 174 Ibs. of non-nitrogenous extractives, The superior digestibility of 
properly dried hay is another factor which enters into such calculation. 
Rain falling on the hay causes losses and still further diminishes the value. Kellner examined two 
lots of hay; the one was very carefully dried, the other lay in the open air for four and a half days 
and during this time a thunder-storm occurred and a light shower of rain fell, The exposed lot gave 
7.13 °/o less hay than the other. 
Analysis of both lots gave the following results: — 
Lucerne carefully dried. Lucerne exposed to the rain.

Lucerne does not stand depasturing; sheep are specially injurious because they eat 
away the young buds which, if not destroyed, would soon develope into new branches. 
Hint estimates the yield of hay obtained in Switzerland from four or five mowings at amounts 
varying between 3080 and 3520 Ibs. per acre = 28 to 32 cwt. Guido Krafft states that the average 
yield of hay under favorable conditions varies between 5280 and 8800 lbs. = 48 to 80 cwt., but, 
that, during the second and third years, from 10560 to 14440 lbs. = 96 to 104% cwt. are obtained. 
Werner reckons that an excellent soil should give from 7920 to 10560 Ibs. = 72 to 96 ewt., a 
good soil from 5280 to 7040 lbs. = 48 to 64 ewl., and a poor soil from 4400 to 5280 Ibs. —= 40 
to 48 cwt. Calculated from these dala, the average yield of hay is 7040 Ibs. — 64 ewt. per acre. 
Sprengel reckons that 10560 Ibs. = 96 cwl. are obtained from a good soil. Schwerz remarks that, in 
zermany, lucerne gives as much produce in three cuttings as red clover gives in two; but, in France, 
seven cuttings produce from 14960 to 15840 lbs. — 136 to 144 ewt. 
According to Wolff, the composition of hay (containing 14% °/o water) and of green lucerne (con- 
taining 84 °/o of water when young, and 74 °/o before flowering) is.

From this, it is plain that green lucerne is an excellent food-stuff, very rich in al- 
bumin; it is even more nutritive than red clover of medium quality. When green, 
it forms excellent food for milking cattle. For this purpose, it should be cut before it 
gets too old; if not, it becomes hard and then adds rather to the flesh than to the milk. 
As it is rich in albumin, food-stuffs poor in this respect can be mixed with it, for example, 
Depasturing.
