ANIMAL PEODUCTION. 75 



" The Colorado packer wants a well-tiuished, fat, blocky hog weighing alive 

 from 220 to 250 lbs. During the winter months there is a good, but limited 

 demand for the city whole carcass trade, for well-finished hogs weighing alive 

 from 150 to 175 lbs. each. 



" Most of the Colorado hogs marketed in the past three years have been un- 

 finished and too light in weight. A well-finished hog will dress 80 per cent; 

 the average at the Denver packing houses in 1908 was 73 per cent. 



" The chief trouble has been that most Colorado farmers neglect their hogs 

 through the summer, stunting them, and stunted hogs do not finish well." 



There are illustrations and brief descriptions of a portable hog house, an 

 alfalfa rack for feeding, and the piggery at the Colorado College.

Egg'-laying' competitions at Hawkesbury Agricultural College and Ex- 

 periment Farm, D. S. Thompson (Agi: (Jaz. X. 8. Wales, .U) {1U09), Xo. 6, pp. 

 517-533, figs. 18). — This is a report of the seventh annual and the second 2-year 

 egg-laying competitions. 



The effect of these competitions has been to increase the average egg i)roduc- 

 tion from 130 eggs per hen in the first competition to 180 in the seventh. The 

 size of the eggs has also been increased with a view to reach the commercial 

 standard of 24 oz. per dozen. In the first test the hens in 22 per cent of the 

 pens laid eggs which were undersized. The 2-year test was won by white Leg- 

 horns, which laid an average of 245 eggs the first year and 101 eggs the second 

 year.

 25, pp. 10J,2, lO'i'i, 10',6, figs. 3).— An account of the work of the Danish 

 Farmers' Cooperative Egg Export Association, organized in 1895, and now com- 

 prising 500 circles or local associations aggregating some 4.S.000 members, who 

 pay about 13.5 cts. each as an entry fee. The object of the association is to 

 establish the best possible market in foreign countries for Danish eggs by guar- 

 anteeing that the eggs delivered with the registered trade mark stenciled on 

 each egg are absolutely fresh and clean, and by protecting the general interests 

 of the Danish poultry keepers by preserving eggs, fattening and selling the 

 poultry of the members, and promoting a rational poultry management. The 

 methods of packing the eggs for export are described. The work of the asso- 

 ciation has been very successful. The sales during 1907 amounted to 10,000,000 

 lbs. of eggs and poultry, valued at $1,080,000.

 This is a statistical and general account of the poultry industry of Maryland, 

 much of the information having been obtained by visits to successful poultry 

 farms in the State. 



The methods of housing are described in considerable detail. There are de 

 scriptions of colony and continuous houses, both with open and with closed 

 front. Other topics treated are incubation, natural and artificial brooding,
