while four others in the boxes and five in the shed were fed on un- 
decorticated cotton-cake. After about a month of feeding, however, 
No. 1 bullock in the boxes, belonging to the decorticated cake lot, 
developed a swelling in its neck which prevented it from eating its 
food properly ; and, although the animal ultimately recovered and 
nearly made up for lost time, it would not be fair to include it in 
the experiment ; therefore it is omitted throughout. In order 
to avoid, as far as possible, upsetting the animals by weighing them 
at the arranged intervals, the bullocks were purchased early in the 
year (June 1890) and summered on the farm, being weighed several 
times durmg the period in order to accustom them to being handled. 
They were 3-year-old Shorthorns when purchased, and cost 16^. Ps. 
each, the average live- weight per head being 9-s cwt. Throughout 
tie summer they only had grass and a little rough hay ; latei', when 
brought into the yards, the food of all was kept alike, so that they 
started under equal conditions. The foods given during the experi- 
ment were the same as in the 1888-9 experiments, viz. : —

The bullocks commenced feeding with 3 lb. of linseed-cake, 
1 lb. of barley, and 2 lb. of cotton-cake per head daily. With the 
view of bringing out any diflference between the two kinds of cotton- 
cake the above quantities of linseed-cake and barley were kept to 
throughout, but the cotton-cake was gradually increased, viz. on 
Jan. 11, 1891, to 4 lb., on Feb. 8 to 6 lb., and on March 22 to 
8 lb. of either cake per head daily. The experiment began on Dec. 
11, 1890, and closed on April 11 and on April 18, thus lasting for 
120 days and 127 days respectively. It was divided further into 
periods of 40, 42, 38 (or 45) days, at the end of each of which 
the bullocks were weighed. The foods consumed and the daily 
average per head were : —
