Helafive J/amirial Value. — As the ballocts in the foregoing ex- 
periment were kept in boxes, all the dung thev made was saved. I 
thonght, therefore, it would add interest to the trial if the two lots 
■were kept separate and tried upon crops. Accordingly this was 
done, and the mantire was used for potatoes. The experiment is 
described in the .Journal, Third Series, Vol. II., 1891, Part H., pp. 
376-7. Brieflj, the results were : —

The superiority of the decorticated cake, both for feeding and 
manurial purposes, was thns clearly brought out by the experiment.

The repetition of feeding experiments is not only desirable, but 
frequently also very necessary for the elimination of accidental 
factors which may have exercised an influence on the results 
obtained. Besides, when an experiment has been repeated once or 
twice, under varying circumstances, and the same result in the main 
is arrived at, the broad general truth to be derived from . it is the 
more firmly established. Seeing the importance of the result 
obtained in lSSS-9, it was consideretl desirable by the Wbbum 
Sub-Committee to repeat in 1890-1 the previous experiment with 
decorticated and nndecorticated cotton-cake upon buUocks. As 
Herefortl bullocks had been used before, Shorthorns were now tried. 
The number of animals was also larger, for, instead of ha^-ing only 
four in each lot, it was intended to have nine ; and accordingly not 
only the feeding-lx>xes, but also the enclosed shed and the open 
yard were utilised. The yard, it may be mentioned, has shelter 
proWded at one end of it by a shed. Experiments have frequently 
been made for the purpose of seeing whether any practical difference 
has resulted from feeding in the boxes, in the shed, or in the open 
yard, but no real difference has been traced, except that, of cotirse, 
in the boxes all the manure is carefully storetl and no urine wasted or 
superfluous litter used. Of the nine animals to be fed on decorticated 
cotton-cake four were put in the boxes and five in the open yard,
