38 EXPERIMENT STATION RECORD. 



fire pots or similar appliances may be greatly increased by the use of some 

 sort of cover device, and describes a cover suitable for the protection of de- 

 ciduous fruit trees, and witti some modification, for use witli vines, garden 

 truck, flowers, and similar crops. 



"The cover consists of a reasonably cheap and light-weight material, yet 

 sufllciently tough to withstand out-of-door exposure, and is rainproof. It is 

 essentially a paper cover, and the principle, indeed, is the same as used by 

 many housekeepers and gardeners to protect favorite plants, namely, by cov- 

 ering them with newspapers or cloths. . . . The material can be made in 

 double sheets with an intervening air space, which gives a very high degree of 

 protection. For ordinary use a single layer will suffice. . . . The covers can 

 be made in any size. There is a small central frame of wood, cross braced, 

 to which the paper is tacked. From the central frame flaps of the cloth paper 

 extend, and there are suitable lacing strings provided to bring the ends of the 

 flaps together and also to fasten the cover edges to the tree trunk, so that 

 the cover remains in place should wind arise during the night hours." 



Garden management, A. G. B. Bouquet {Oregon 8ta. Circ. 11, pp. 8, figs. 

 3). — This discusses in a popular way some of the important points in the 

 management of a vegetable garden. The phases considered are seeds, soil 

 preparation, arrangement of crops, seed sowing, thinning, fertilization, and 

 transplanting. 



Garden profits, E. L. D. Seymour (Cjardcu City, N. Y., 1911, pp. 2-'i5, figs. 

 58).— A popular treatise on vegetable growing, including the management of 

 cold frames and hotbeds, designed primarily for back yard and suburban gar- 

 dens. In addition to general and specific cultural directions, the records of 

 a number of small, successful gardens are given, together with a working 

 calendar for the year, and chapters on fertilizers, plant diseases and insect 

 pests and their control. 



Fertilizers on asparagus, C. P. Close, T. H. White, and W. R. Ballard 

 {Maryland SUi. Bnl. 151, pp. 135-11/6, figs. 2). — A fertilizer experiment with 

 asparagus, planned by H. J. Patterson and "W. N. Hutt and conducted con- 

 tinuously from 1905 to 1910 inclusive, is reported. Concise directions are 

 given for starting and caring for an asparagus bed. The experimental bed was 

 started with 1-year-old plants in 1903 on medium loam of good fertility. Com- 

 parisons and tests were made of commercial fertilizer versus barnyard manure, 

 different sources of potash, light and heavy applications of kainit, heavy appli- 

 cations of nitrate of soda in spring, heavy applications of salt, manure in 

 different amounts with and without commercial fertilizer, and different times 

 of applying manures and fertilizers. The various treatments, including the 

 results as indicated by the yields and costs of the diffei'ent treatments, are 

 tabulated and discussed. 



Cabbage, L. C. Corbett {U. S. Dept. Agr., Farmers' Bui. Ji33, pp. 23, figs. 

 11). — This bulletin contains detailed directions for the culture of cabbage as 

 a truck crop, market-garden crop, and farm crop, including information rela- 

 tive to the soil, fertilizers, starting and transplanting, cultivation, control of 

 insects and diseases, harvesting, varieties, marketing, and storage. 



Observations on screening cabbage seed beds, W. J. Schoene {'Neiv York 

 State Sta. Bui. 33Ji, pp. 13-3//, pis. 2, chart 1). — The observations here recorded 

 were made in order to determine the cost of screening and to show what cab- 

 bage growers have accomplished in protecting their seedlings in the manner 

 recommended in Bulletin 301, previously noted (E. S. R., 20, p. 59). 



The 2 principal seed bed pests thus dealt with, namely, the turnip flea beetle 

 {Phyllotrefa vittata) and the cabbage maggot {Pegomya sp.) are briefly con- 

 sidered. The relation of the usual time for growing late cabbage seedlings to
