EXPERIMENT STATION RECOED. 



[Vol. 38 



naent Station, attention is called to the necessity, owing to the increased cost, 

 of utilizing every source of animal protein. The efficiency of animal protein 

 over that of vegetable origin is noted and certain experiments are cited to 

 bear out the statement. It is further pointed out that both wild and domesti- 

 cated birds seek insects, two of which — grasshoppers and June bugs — studied by 

 the author, show a high lysin content. June bugs, while containing a slightly 

 greater protein content, are not so plentiful as grasshoppers and are not there- 

 fore so economical as a source of protein. The grasshoppers contain a higher 

 protein content than meat meal, and could be dried and used in rations for live 

 stock. 



The following analyses of grasshoppers and June bugs, compared with lean 

 beef and white turkey meat, are reported :

[Report of poultry laying competitions, 1913—1915], F. W. Rhodes et al. 

 (Harper Adams Agr. Col. Bids. 1 (1914), pp. 50, pis. 5, figs. 7; 1 (1915), pp. 83, 

 figs. 4; 1 (1916), pp. 54, pis. 7, fig. 1). — Detailed reports are given of the first 

 three annual egg-laying competitions conducted by the Harper Adams Agricul- 

 tural College, Salop County, England, in conjunction with the Utility Poultry 

 Club. The first two of these contests lasted 12 months each, and the third 10 

 months. Tabulated data show the egg production, etc., of each bird in the 

 contest. The average egg yield per bird during the first contest was 151.9, 

 during the second 187.2, and during the third (10 months) 168.5. 



Egg--laying tests at Hawkesbury Agricultural College, 1916-17, G. D. 

 Ross and J. Hadlington (Agr. Gaz. N. S. Wales, 28 (1911), No. 5, pp. 337-355, 

 figs. 11). — This is a detailed report of the fifteenth annual egg-laying contest 

 held at the Hawkesbury Agricultural College. This competition was the first 

 one of this series that has been conducted entirely upon the basis of single-hen 

 pens for first-year hens. A Black Orpington hen laid 312 eggs and a White 

 Leghorn hen laid 308 eggs during the 365 days of the contest. These are said to 

 be world's records. 



Marketing eggs by parcel post, L. B. Flohr (U. S. Dept. Agr., Farmers' 

 Bui. 830 (1917), pp. 23, figs. 7).— A summary of the conditions and possibilities 

 of the parcel post in furthering direct sales between the producer and the con- 

 sumer of eggs. 



The work is based on the results attained in trial shipments of about 761 

 doz. eggs in lots of 1 to 10 doz. each. Of the whole, 327 eggs were broken, of 

 which 209. or 2.3 per cent, were beyond use. 



Essentials to successful marketing are pointed out, containers described, and 

 postal regulations given.
