1070 EXPERIMENT STATION RECOED. 



ferent in size, weight, actiou or tlie use to which they are put. Mules are not 

 divided into subclasses. 



"The uiarlvet classes are: Draft horses, chunlvS, wagon horses, carriage 

 horses, road horses, saddle horses, mining mules, cotton mules, sugar mules, 

 fai'm mules, and draft mules. . . . 



" The grades distinguish the good from the poor animals within the classes and 

 subclasses. The grades are choice, good, medium, common, and Inferior. . . . 



" The breed to which a horse belongs has but little influence upon his market 

 value, and the classes are not determined by the breeds, but by the individuality 

 and conformation of the horse; however, a .iudicious use of choice pure-bred 

 sires is best suited for the production of marketable horses." 



The characteristics of the different classes and grades are considered in detail. 



The Asiatics — Brahm.as, Cochins, aiid Langshans — all varieties {Quincy, 

 III. [1907], pp. 96, pis. 2, figs. 71). — A number of papers by different authors on 

 the Asiatic breeds of poultry. The origin of Asiatic breeds, their peculiarities, 

 egg production, market qualities, breeding, and related questions are discussed. 

 The majority of the papers are reprinted from Reliable Poultry Journal. 



Poultry for export, H. V. Hawkins (Jour. Dept. Ayr. Victoria, 5 (1907), 

 No. 9, pp. 5./i't-5Jf6, fig. 1). — In a discussion of trade requirements, production 

 of white flesh, and related questions, the author describes a light and con- 

 venient crate for shipping poultry. 



Chicken coops, H. de Courcy {Jour. Bd. Ayr. [London], IJf {1907), No. 6, 

 pp. 368-370, fiys. 4). — The construction of chicken coops of different sorts, which 

 the author considers satisfactory, is described. 



Electric incubators {8ci. Amer., 97 {1907), No. 19, p. 336, figs. 5). — An incu- 

 bator is described in which heat is sui)plied by electricity. 



Fifth annual international egg-laying competition, D. S. Thompson {Dept. 

 Ayr. N. S. Wales, Misc. Pub. 1093, pp. 21, figs, i^).— The average egg yield 

 recorded was 171 per hen in the G-months' test, the cost of feed $1.40, and the 

 average profit over feed $2.16. In a breed test the largest average egg yield, 

 190.16 eggs per hen, was obtained with Cuckoo Leghorns. Some general data 

 are given regarding foods and feeding, egg market, and related questions. 



Different methods of preserving eggs, R. Nourisse {Les Divers Procedes 

 de Conservation dcs CEufs. Paris, 1907, pp. 31). — The author has summarized 

 and discussed data on the preservation of eggs by cold storage, preservative 

 solutions, evaporation, etc. 



Squab investigations, C. K. Graham {Connecticut Storrs Sta. Bui. 50, pp. 

 13-59, figs. 20). — For several years the station has possessed pigeon lofts and 

 has studied experimentally various questions connected with squab raising under 

 conditions similar to those of individuals attempting squab raising for market. 

 On the basis of experience gained and data recorded various questions concerned 

 with the feeding, care, mating, management, and housing of pigeons, the killing 

 and marketing of squabs, and similar topics are discussed. 



Pigeons, the author notes, depreciate in value with age and are considered to 

 be in their prime when 3 years old. Very few pairs " pay for their feed after 

 they are 7 years old. . . . 



"There are many varieties of pigeons that are used for squab producers, but 

 pi'obably the most common is the Homer. These are very vigorous birds, and 

 there are few breeders who do not consider a certain amount of Homer blood 

 essential. They are often crossed with Runts, Duchesses, or Dragoons. The 

 Runt is a very heavy bird, but in most, cases is considered a little slow in pro- 

 ductiveness, while the Duchesse gives a feathered-leg squab, but has a tendency 

 to increase the weight. . . .
