Feeding Experiments at Wohuim. 
This cake is made by cnishing the seeds and seed-pods of 
Arachis hypogea, a plant cultivated extensively on the northern 
coast of Africa, and also largely in India, more particularly in 
Southern India. Large quantities of the seed-pods are exported 
from Pondicherry (Madras), and go principally to Mediterranean 
ports, the oil, after crushing of the seeds, being used for adul- 
terating olive oil and for other purposes. The refuse cake is 
used for feeding cattle, both on the Continent and in India. 
Very little of the cake has as yet been brought over to this 
country, but as there was some likelihood last year (1891) of a 
trade in it developing, it was thought well to try at the Woburn 
Experimental Farm how the material would do as a food for 
cattle. The principal objections to its use are that, owing to 
the rough method of pressure employed, the cake is often apt to 
have some amount of horse-hair or bits of rough sacking (from 
the bags used in pressing out the oil) attached to it, and that 
it is very liable to turn rancid and to become sour. These 
points should be guarded against. The cake supplied to Woburn 
was fairly free from pieces of sacking, and any which were 
noticed were picked out before the cake was given to the 
animals ; it was also free from rancidity, but was, however, 
slightly acid. 
Four Hereford bullocks were fed from November 28, 1891, to 
March 14, 1892 (107 days), with a mixture of earth-nut cake, 
oats, and barley in equal pi’oportions, and received in addition 
about 451b. of roots and 151b. of clover-hay chaff per head 
daily. The experiment was thus parallel to that with beans, 
oats, and barley, described in the previous article, the only 
difference being that earth-nut cake was used in place of l^eans, 
so that the present may be considered ns a trial of earth-nut 
cake against beau-meal. The cost of the earth-nut cake was 
8/-. 4s. a ton, delivered at the nearest station, which, with cartage, 
breaking, &c., brought the price up to 81. 8s. a ton. Analyses 
of average samples, taken during the experiment, gave the
