14 N. H. AGE. EXPERIMENT STATION. [Bulletin 192 



Agricultural Research; the third, on "A Chest Contour CaUper and Its Adapt- 

 ability for Measuring Sheep," was issued as a Station circular. 



In addition to this, two practical bulletins, one on "Sheep Breeding in New 

 Hampshire" and the other on "The Sheep Industry in New Hampshire," were 

 published in behah of the New Hampshu-e Sheep Breeders' Association. An 

 article on "Raising Beef in New Hampshire" was prepared for the report of 

 the state commissioner of agriculture, and one circular, numerous timely arti- 

 cles for the press, and one poster prepared by the animal husbandman for the 

 food production campaign were published during the year. 



The Department has two co-operative projects in research with the Carnegie 

 Institution of Washington. In the first of these, the sheep breeding experi- 

 ments, the co-operation is purely of a consulting nature on the part of Dr. C. B. 

 Davenport representing the Station for Experimental Evolution of the Carne- 

 gie Institution. In the second of these, the nutrition experiment, the co-opera- 

 tion involves equal financial obhgations. 



"WTiile the activity of the animal husbandman as secretary-treasurer of the 

 New Hampshire Sheep Breeders' Association is not co-operative, a considerable 

 amount of work was done in the organization and education of farmers on sub- 

 jects relative to the sheep industry and its improvement, thus reheving the 

 Station from similar work. 



No special equipment has been added except the chest contour caliper which 

 was designed by the Department and built here. 



All of the projects are carried on under the Adams and miscellaneous funds. 



SHEEP BREEDING EXPERIMENTS. 

 HisTOBY OF Experiment. 



The experknental work with sheep, as originally planned (1906) and carried 

 out by F. W. Taylor and E. L. Shaw, consisted in the production of spring 

 lambs for market. 



In 1908 this early lamb project was revised by W. H. Pew and E. D. San- 

 derson with the object, first, "to determme the principles involved and the 

 best methods to be employed in grading up a flock of sheep, particularly for 

 early lamb production, studying the characters of crosses with reference to 

 Mendel's Law" ; second, "to determine the principles involved in fixing certain 

 characters in sheep, studying the closeness with which the characters of the 

 hybrids follow Mendel's Law and their appUcation to breeding problems." 



During the first two years following the revision of this project the majority 

 of lambs were fitted and sold for early market so that the project as a breeding 

 experiment lost its value from a MendeUan point of view. 



Following this period the work was for two years under the direction of 

 T. R. Arkell, who gave more attention to the problems relating purely to 

 inheritance. At this time the main work consisted in hybridization along 

 Mendelian fines of the Hampshire and Rambouillet breeds, and a bulletin was 

 issued on the method of transmission or inheritance of horns in sheep. Some 

 Hatch work in feeding on "Feeding Sheep and Lambs: Clover Hay v. Native 

 Hay; Turnips v. Dry Ration" was also made public in the form of a Station 

 bulletin.
