ANIMAL PFiODUCTION. 865 



Many corn and oaf feeds contained oat bulls and most of them showed the 

 presence of salt. Of the 040 Siimples examined, 402 were below guaranty iu fat. 



Analyses of ground corncobs, corn bran, oat hulls, wheat screenings, cotton- 

 seed hulls, and rice hulls, which are common adulterants of feeding stuffs, are 

 also given. A method of figuring rebates on commercial feeding stuffs is 

 describeil. 



Investigations of feeding stuffs, II. Immendorff (Ber. Luiulw. Vers. Htat. 

 L'nir. Jena, 1907, pp. lO-li). — This report contains analyses of 374 samples of 

 cotton-seed meal, peanut meal, iialm meal, linseed meal, rice feed meal, dried 

 brewers' grains, and sesame meal. 



Inspection and regulation of feeding stuffs, W. Kinzel {Vrtljschr. Bayer. 

 Landic. Rat., Li (1908), No. 2, Sup., Bellagc 3, pp. 35-59). — There were in- 

 spected 2.520 samjiles of feeding stuffs, nearly double the number of the 

 previous year. A large percentage were found to l)e adulterated. 



St. John's bread, a competitor of molasses feed {Dvul. Zuckcrindus., 33 

 {1908), Xo. '19, p. 9.')C)). — A note on the increased use of this feed in Germany. 

 Analyses are given. 



The Roseworthy Agricultural College flock in 1907—8, A. J. Perkins (Jour. 

 Dept. Agr. So. Aust., 12 (1908), Xos. 1, pp. 10-25; 2, pp. J 11-128; 8, pp. 227-250. 

 figs. 7). — A report of experimental work to ascertain what number of live stocli 

 can be kept under average conditions, with a view to improving the yielding 

 capacity of the land. The number of acres used, including buildings, yards, and 

 roads, was 1,434. and the average stoelc kept for the year 43 horses, 70 cattle, 290 

 pigs, and 1,3S2 sheep. Pastures wei-e used each month, and rotation of pastures 

 is x'ecommended. Rooted perennials like Golden Crown grass or perennial rye 

 grass are recommended for green feed for early lambs. A field of 43 acres of 

 rape carried an average of 3i sheep to the acre for the year, and a field of 00 

 acres of barley stubble carried an average of 4i sheep per acre. Properly man- 

 aged it is believed that a 3-year rotation of bare fallow, wheat, and grazing 

 should carry 1 sheep per acre for the year, and that only one-fifth of the total 

 area need be thrown open to grazing. 



'• Catch crops will never involve us iu much expense. For the most part they 

 will call for no more than slight early autumn tillage of cereal stubbles and the 

 broadcasting of such crops as rape, mustard, crimson clover, sulla, and perhaps 

 vetches either alone or in combination with one of the cereals. Fallow crops, 

 on the other hand, will always involve us in far greater preparatory expendi- 

 ture, a portion of which, however, must be borne by the cereal crop that follows. 

 Some of these fallow crops render necessary early autumn plowing, a heavy and 

 laborious task when the land lies hard and dry; of such are kale, kohl-rabi, and 

 perhaps turnips. ... On the other band, we have fallow crops that can be sown 

 later in the season when wheat-seeding operations have l)een completed. For 

 instance, such as peas, vetches, mustard, and perhai)S turnips. . . . Fallow crops 

 of this kind involve us in less expense than those previouly referred to. Finally, 

 we have the spring-sown summer crops such as sorghums, millets, maize, etc., 

 of greater use on tlie whole for ensilage purposes and to dairy cattle tlian to a 

 flock. . . . Whatever is done in this direction it is well to recollect that no 

 forage crop can be raised to any advantage that does not dovetail in with the 

 general economy of the farm practice of the district." 



With various crosses of sheei) it was found Ihiit the largest sheep did not 

 malce as good use of what pastures were available as tlie smaller, but more 

 compact, Merino-Southdown. Slightly heavier fleeces were obtained, on an 

 average, from 102 Merino-Shro|tshire ewes than from 502 pure Merinos. There 

 was no pronounced difference in the weight of the fleece whether the ewe bore
