" During tlu; past L'o yeai-s a great aniomit of evidence hearing on breed merit 

 has been seeuretl at the agricultural experiment stations, at expositions, on race 

 courses, and at fair gi'ounds. In the breed reviews in this work much of this 

 receid evidence is given a place. Brief consideration is also given to some of 

 liie more important foiuid ition families or tribes, and to individual animals that 

 have made a deep imiiression ui>on the breed. The author has taken the Iil)erty 

 of conmienting on the weak as well as on the strong points of the breeds, hut this 

 h;is been done in a nonpartisan si)irit. in harmony with the views of capaltle 

 critics. 



"These Itrief studies of the tyi)es and breeds of farm animals are naturally 

 far from complete. They are intended for the stud(>nt or the stockman who sees 

 the long road of education i)efore him. The subject-matter is ai-ranged with 

 some regard to systematic gi'ouping. with the hope that it may in a measure 

 meet the requirements of th(> cl.-iss room, the teacher, and the i>r;ictical stockman 

 on the f.'irm." 



The volume as a whole constitutes an important sunnnary of available data 

 legarding types and breeds of farm animals, and will prove generally useful to 

 readers interested in the subject as well as to students of agriculture. 



Farm animals in Montenegro, Bosnia-Herzegovina, and Dahnatia, A. 

 I'iKoccHi {Aim. Ai/r. [Italy], li)06. No. 2.'i6, pp. J.')5, fign. 34). — A summary of 

 statistical aaid other data regarding the iiroduction juid management of farm 

 animals in the Ualkan .states. 



Balanced rations and the influence of nitrogen equilibrium on gains made 

 by sheep, J. Fabre {Ann. Ecole Nat. Agr. MontpelUer, ii. scr., G (1906), Nos. 1. 

 pp. 6G-S0, dynis. 2; 2. pp. S1-S9). — The digestible nitrogen supplied in the differ- 

 ent experiments ranged from about G to 37.1 gm. per head per day. Tlu; 

 balance of income and outgo of nitrogen was determined in the experiments 

 and variations in weight were recorded. It was found that the rations fur- 

 nishing the larger amounts of protein induced greater gains of nitrogen and 

 larger gains in body weight. 



Crossbreeding for mutton in the north of England, W. T. Lawrence 

 (J'no: lid. Ayr. [London], IS (1006), No. 9, pp. :,r.^-',20. fiys. 3).— The general 

 subject of crossbreeding mountain sheep for the i)roduction of mutton is dis- 

 cussed and some recent tests carried on by the author are briefly referred to. 



In one test the Oxford-cross lambs matured more (piickly and were less 

 expensive than the other crosses. In the second test the Border-Leicester 

 cross was regarded as preferable for fat lambs, though the Wensleydale cross 

 v.-as more satisfactory for the production of rajtidly growing sheep for subse- 

 (luent fattening. 



As the author points out, " the wether land)s of the pure mountain breeds are 

 allow^ed to take their time to grow and fatten on their native fells and do not 

 come into the nnitton market except as shearlings or two-shear sheep. A Herd- 

 wick two-shear fat aether is the acme of mutton production for quality and 

 flavor." 



The digestibility of barley grits by-products, F. Barnstein and .J. Voi. 

 HARD (fjindn-. Vers. ^tat.. 65 (1906). No. .>,-',. pp. 221-236). — Using 2 sheep the 

 digestil)ility of so-called barley feed meal, barley bran, and a by-product con- 

 taining a very large proportion of the hull was studied. The basal ration was 

 made up of meadow hay and cotton-seed meal ;ind the digestibility of the feed-
