The Missouri poultry house, H. L. Kempster (Missouri Sta. Circ. 80 (1916), 

 pp. 8, figs. 5). — This circular describes and illustrates tlie Missouri poultry 

 house, giving bills of material and costs. 



" Since the average farm poultry flock in Missouri is from 100 to 150 hens, 

 this house is 20 ft. square, the square house being the most economical to con- 

 struct and affording a maximum amount of floor space. The ridge of the 

 roof runs nortli and south, the roof being of equal spans. The walls are 

 5 ft. at the eaves. It is 11 ft. high at the peak. The south side contains a door 

 in the center and a window 2 by 3 ft. on each side of the door. These windows 

 are placed high enough to afford a 30-in. opening beneath, 1 ft. above the floor 

 and extending the entire length each side of the door. This opening is covered 

 with wire screen, which keeps the hens in and the sparrows out." 



Details of a trap nest are also included. 



RURAL ECONOMICS. 



A preliminary study of the marketing' of Burley tobacco in central Ken- 

 tucky, C. D. BoHANNAN and D. P. Campbell (Kentucky Sta. Bui. 202 (1916), 

 pp. 157-2^47 Pl^s. 8, figs. 10). — This is the first of a projected series of studies 

 on the marketing of Kentucky farm products. 



The culture and curing of Burley tobacco, which is now the greatest cash 

 crop of the blue grass region, is briefly explained, the methods of marketing 

 described in detail, and the relative profits of those handling the crop dis- 

 cussed. 



" Formerly the tobacco was shipped in hogsheads to Louisville or Cin- 

 cinnati or sold in the barn to the buyer for one of the tobacco companies. 

 Now it is, as a rule, sold at auction over the loose-leaf floors, although some 

 crops are purchased in the barns by speculators. 



" The greater part of each season's crop, of which during the last season 

 35,fi>00,000 lbs. were sold in Lexington, is purchased by the agents or ' buyers ' 

 for the large tobacco manufacturers, . . . After sale to a buyer or broker 

 the leaf ."s usually repicked, redried, and prized into hogsheads for shipping or 

 storage." 



The loose-leaf system is stated to be the most economically efficient system 

 yet devised. It is, however, " susceptible of improvement in elimination of 

 waste product and duplication of effort. From the standpoint of both grower 

 and manufacturer there is much need of improvement in curing methods and 

 in the grading of the leaf as it comes from the stalk. . . . 



" Proper grading applies with peculiar force to Burley tobacco. Approxi- 

 mately 60 per cent of the total amount of tobacco sold over the Lexington floors 

 is capable of improvement by rehandling and resorting. This improvement 

 would result in raising the price at least 2 cts. per pound." 



The need of a state marketing law and the use of standard grades for all 

 farm products, which permits of division into grades, and for standard recep- 

 tacles for products sold in containers is set forth. " No product not graded in 

 accordance therewith slreuld be permitted to be exposed or offered for sale
