The main results, so far as the growth of the sheep is 

 concerned, are stated to be as follows : — 



1. The live-weight gain, per acre and per sheep, was distinctly greater on the 



three manured plots (Nos. 2, 4, 5) than was the case on Plot I, where 

 the sheep got daily considerably more than f lb. per head of linseed 

 cake. A similar result was obtained in Northumberland in 1898. 



2. Plot 2, receiving | ton of basic slag, carried nearly two sheep more than 



Plot 4, which was dressed with half the quantity of slag, but the gain per 

 head per week in the latter case was somewhat higher. 



3. When equal amounts of phosphoric acid were used in the two forms of basic 



slag and superphosphate, the latter produced the larger live-weight gain. 

 A similar result was obtained in the first year of the Northumberland 

 experiments. 



4. The unmanured plot gave decidedly the lowest yield of animal increase. 



Molasses and Dairy Cows. 



Experiments were carried out at Poppelsdorf, Bonn, in 

 1895-6, on the effect of various preparations of molasses upon 

 the secretion of milk. One of the points then investigated 

 was the question whether the influence of a given quantity of 

 sugar was exactly the same when supplied in the form of raw 

 sugar or of molasses ; in other words, whether the dry matter, 

 apart from the sugar, contained in the molasses had abso- 

 lutely no feeding value. It was then found that the molasses 

 had a distinctly higher value than the raw sugar ; the amount 

 uf fats in the milk yielded by cows fed on molasses being 

 considerably greater than in the milk from cows receiving 

 sugar. Experiments made in supplementing the sugar ration 

 by the addition of salts forming constituents of molasses were 

 not, however, successful in raising the fats content of the 

 milk to the amount yielded by feeding with molasses. Cows 

 fed with 0-36 lbs. of sugar (besides a general ration) in the 

 form of molasses yielded 1*92 lbs. of milk containing- 0-0734 

 lbs. of fat per 100 lbs.. of live weight; when fed with raw 

 sugar they gave 1-69 lbs. milk containing 0-0665 lbs. of fat; 

 and when fed with raw sugar with the addition of salts they 

 gave 1-67 lbs. of milk containing 0-0664 lbs. of fat. In these 

 calculations allowance was made for the period of lactation. 



The experiment was repeated during the spring of igco,
