Various kinds of Refuse. 23 



Malt-dust is obtained in the preparation of malt from barley. 

 The small rootlets or radicles which protrude from sprouted bar- 

 ley, after being kiln-dried, constitute the commercial malt-dust, 

 which of course can only be obtained in limited quantity. It is 

 used principally as food for sheep, which like it, and get on upon 

 it very well, if it is supplied to them along with some hay and 

 turnips. 



Malt-dust, it will be observed, contains a very large amount of 

 flesh-forming constituents, and ought therefore to possess a very 

 high nutritive value. However, 1 believe its practical value as 

 an article of food, though by no means distinctly ascertained, 

 is much smaller than from its composition might be expected. 



Barley-dust is used to some extent in feeding cattle, as well 

 as pigs. Now and then it can be obtained at a price which 

 renders it a much more economical food than barleymeal, from 

 which it is distinguished principally by a larger amount of woody 

 fibre. 



Oat-dust. Mixed with chaff and thoroughly saturated with 

 water, this refuse is extensively employed either alone or with 

 roots in feeding cattle. It ought not to be given to cattle in a 

 dry state, for it is very slowly moistened, and therefore apt to 

 form dust-balls in the stomach. When given to dairy cows it is 

 found to increase the yield of butter. 



Brose-meal Brock is the refuse obtained in making peas.- 

 meal. Brose-meal brock contains about as much muscle sub- 

 stance as barley-meal, but too much indigestible fibre, and too 

 little starch and fat-producing substances. It is employed in 

 feeding, as a cheap substitute for bean-meal, and used like it. 



Pea-hulls from Maple-peas. In making split peas, the outer 

 skins of the pea are removed and sold under the name of pea- 

 hulls, as another cheap substitute for bean-meal. Pea-hulls, how- 

 ever, do not possess much value as a feeding-substance, and 

 ought therefore not to be employed unless they can be got at a 

 very cheap rate. 



Rice-dust , or rice-meal, is a refuse obtained in cleaning rice for 

 our market, and consists of the husks and external layers of rice, 

 together with fragments of the grain itself, with some accidental 

 foreign impurities. In Liverpool it is produced in large quan- 

 tity, and often sold much above its real value. 



Rice-dust is said to increase the yield of milk, and is employed 

 therefore to some extent by Cheshire farmers for feeding milk- 

 cows. It has also beeri found to be a good food for fattening 

 pigs. 



The above analysis shows that rice-dust is rich in ready-made 

 fat, a circumstance which fully explains its adaptation for fatten- 

 ing purposes. It will be observed likewise that rice-dust contains
