368 EXPERIMENT STATION RECORD. [Vol. 37 



After the animals were slaughtered various samples were taken from a 

 medium sized and well-nourished hog of each lot, and the melting point and 

 iodin number determined. The data are submitted in tabular form. A wide 

 variation in the melting point was observed. With the exception of the back 

 fat of lots 1 and 3 and the flank fat of lot 4, the melting points of all the sam- 

 ples of lots 1, 3, 4, 5, and 6 were found to be rather low and close together. 

 The samples taken from lot 2 showed a much higher melting point. It is noted 

 that this indicates " that cottonseed meal does have a hardening quality when 

 fed in a balanced ration with milo maize chop." The samples of leaf fat in gen- 

 eral showed a much higher melting point than the samples of fat taken from 

 the back, shoulder, and flank.

Fifth annual international egg-laying contest, W. F. Kirkpatrick and L. E. 

 Card (Connecticut Storr.<< Sta. Bui. 89 (1917), pp. 2S5-A01, figs. 21).— A brief 

 discussion is made of the growth of egg-laying competitions in the United 

 States, and a detailed report is given of the fifth contest at the Storrs Station. 



It Is noted that the mash and grain mixtures used in the earlier contests 

 (B. S. R., 36, p. 570) were made up of no less than 14 different fee<ls in various 

 proportions, whereas the simplified formulas used in this contest necessitate*! 

 the use of only eight Ingredients, and these were, with two exceptions, mixed 

 equal parts by weight. 



The average annual egg yield per hen in the first four conte.sts was 151.5 

 eggs. In the fifth contest, on the simpler rations, the hens averagetl 162 eggs 

 each for the year. 



The scratch feed consisted of wheat and cracked corn (1:1). The dry mash 

 was made up of wheat bran, corn meal, ground oats, flour middlings, fish scrap, 

 and beef scrap (2:2:2:2:1:1). 



The number of hens in the four principal breeds and their average pen scores 

 at the opening of the contest were as follows: White Leghorns, 350 hens, score 

 91.8 per cent ; Rhode Island Rods, 210, 87.2 per cent ; Wyandottes, 170, 90 per 

 cent ; and Plymouth Rocks, 170, 88.1 per cent, respectively. 



All the pens taken together laid 4,667 unrecorded eggs, or 2.88 per cent of the 

 total egg yield.
