Silage for Milk Production. 



[Apr., 



Is a very good " copper " hop, and an excellent commercial 

 variety for heavy soils. 



Rodmerskam Golding. — Not grown except in a few districts in 

 Kent on good loams. Has a weak constitution and the hills are 

 liable to die away from " canker." Easy to pick. Highest 

 quality. 



Late Varieties. — Petham Golding and Canterbury Whitehine. 

 — Only grown on the best loams, chiefly in Kent. Frequently 

 grow too much bine, and in wet summers develops only a small 

 crop. Highest quality. Althougli the quality is second to none, 

 the area devoted to the cultivation of these two varieties is now 

 small. 



Colgates. — The latest hop; grown on heavy land, . chieflv in 

 the Sussex Weald and in Herefordshire. Crops heavily, but the 

 cones are small. A copper " hop. 



SILAGE FOR MILK PRODUCTION : 



A COMPAEISON ¥/ITH ROOTS AND HAY.

In March, 1921, it was decided to discontinue the Ministry's 

 Arable Dairy Demonstration Farm near Denbigh, and the 

 Ministry offered a quantity of silage, then in a clamp on the 

 farm, for the purpose of a feeding experiment. 



Owing to the shortness of notice and the rapid approach of 

 the grass season, nothing in the way of an elaborate experiment 

 could be arranged, and as most farmers in the district had large 

 root surpluses, it was not easy to secure a suitable farm for the 

 experiment. Ultimately, Messrs. Hooson, of Brookhouse and 

 Colomendy farms, near Denbigh, kindly consented to carry out 

 the experiment, and grateful acknowledgment is due to them 

 for the ready and willing help they rendered throughout. Milk 

 recording was immediately commenced on their farms to 

 facilitate the selection of two uniform lots of cows. 



It was decided that each experimental lot must include at 

 least eight animals, and it soon became obvious that it would 

 be impossible to get two such comparable lots on one farm. As 

 the best arrangement possible under the circumstances, eight 

 cows were selected at Colomendy and eight at Brookhouse.
