" Sour skim milk. i. e., milk thai is thickened, is without doubt the host liquid 

 to mix with graiu rations where a uniform product is wanted, and more so 

 where white-fleshed chickens arc in demand. Sweel skim milk has n<»t a 

 feeding value for grown chickens equal to sour milk. Whey Is a better food 

 than is generally considered. The results appear to indicate that it aids 

 digestion. Whey and pork scrap have qo1 given the results expected, and . . . 

 this combination lis qoI recommended]. Where pork scrap and beef scrap 

 cmii be procured a1 reasonable cost, say 2 cts. or less per pound, they arc good 

 value, especially where ;i yellowish flesh is in demand. Grain mixtures only 

 mixed wit 1 1 water are not economical considering this test." 



Artificial incubation, E. Bbown (Jour. Bd. Agr. [London], 12 (1905), Wo. .'. 

 ///*. 87 96, fig. I. (hiins. 8). -The results of incubation experiments carried on at 

 the Reading College Poultry Farm are summarized. 



"The results of the year's operations have been eminently satisfactory, and 

 to secure with so large a number an average of 75.82 per cent is indicative of 

 the success attending the use of artificial methods of hatching under suitable 

 conditions and with well-niade reliable machines. 



"liens have chiefly been employed Cor the hatching of ducklings, and the 

 extent of observations with incubators was too limited to make any special 

 records."

The author calls attention, in discussing the utilization of by-products, to 

 the fact that the fresh blood obtained when the chickens are killed may advan- 

 tageously be fed to live poultry. "Because of the high percentage of protein 

 it contains, it is especially valuable as food for laying and young stock. It can 

 be most conveniently fed by mixing in the mash feed." 



The losses in weight in killing and dressing ."•."»! cocks, cockerels, hens, and 

 pullets were recorded. On an average the weight of the birds bled and plucked 

 Was 9.4 per cent less than the live weight. With the intestines, head, and feet 

 removed, the dressed birds weighed -'>.- per cent less than alive.

A yard having bushes as shelter should be provided and inclosed with netting, 

 in short, an attempt should be made to approximate their natural surroundings 

 as closely as practicable. A house is not Deeded, but some shelter is useful ill 

 wilder. The birds do not lay until they are two years old. The yards should he 

 covered with wire netting, or if this is not convenient the wing may be unjointed 

 at the first joint to prevent flight
