College joint experiments are reported on by Dr. Wilson 

 and Mr. Hendrick in the Transactions of the Highland 

 Society for 1905, p. 271, and 1908, p. 269. 



Downan station is reported on by Professor Patrick Wright 

 in "Reports on Experiments," 1905, p. 116. 



Mr. Greig's report on the Kincardine and Ross stations 

 is issued as Bulletin No. 16 of the Aberdeen and North of 

 Scotland College of Agriculture. 



Method of Summarising the Results. 



In attempting to summarise the results, the following plan 

 will be adopted : — The first nine years' work on the Tree 

 Field at Cockle Park will first be reviewed and compared 

 with the results obtained at Sevington and Cransley. Where 

 strictly comparable, the results at these three stations will 

 be looked at in the light of the figures produced at the other 

 English stations, and at those in Scotland. The value of 

 the live-weight increase is taken at 3d. per pound. Hitherto 

 in the reports on the English stations this increase has been 

 valued at 3fd. per pound (4d. at Sevington), whereas in 

 Scotland it has uniformly been valued at 3d. Dr. Wilson, 

 in his report on the Scottish experiments, argues convinc- 

 ingly that 3d. per lb. is quite enough to put upon the live- 

 weight increase. If this figure be adopted, it brings the 

 butcher's estimate and the live-weight increase valuations at 

 Cockle Park into very close agreement. (See page 5.) More- 

 over, the rate of 3d,. per pound receives strong support from 

 the results at Sevington. There the sheep have always been 

 bought specially for the experiments, and at the end of the 

 season they have all been sold. In the best year at Sevington 

 (1905) 130 sheep were bought for £252 12s. 6d. delivered. 

 They weighed 11,206 lbs. unfasted, or, deducting wool 

 (900 lbs.), their net weight was 10,306 lbs. The wool realised 

 ,£39 7s. 6d. so that the net cost of 10,306 lbs. (live weight) 

 of sheep was ^213 5s., which is just under 5d. per lb. During 

 the course of the experiment two sheep went wrong and had 

 to be sold at £1 each. Deducting these, we start with 

 10,134 live-weight pounds of sheep, costing ^210 3s., after 

 allowance is made for the two sheep at 31s. each shorn. The 

 128 sheep increased 4,828 lb. during the season, and sold
