344 EXPERIMENT STATION RECORD. [Vol.38 



Everyman's garden in war time, C. A. Selden {New York: Dodd, Mead d 

 Co., 1917, pp. XIV-\-S38). — A popular treatise on home gardening and fruit 

 growing, including a weekly working calendar. 



Report of the State horticulturist, C. L. Wilkins {Agr. of Maine, 1916, pp. 

 38-76). — A brief report on the inspection of nurseries and orchards and prem- 

 ises, as well as foreign-grown nursery stock imported into the State of Maine 

 during 1916. Short papers on markets by H. A. Emerson and on birds of the 

 orchard by W. E. Powers are also included. 



[Report of horticultural investigations], O. B. Whipple {Montana Sta. 

 Rpt. 1916, pp. 175, 176). — Mulching experiments with vegetables were continued 

 during the year (E. S. R., 36, p. 236). Cabbage, cauliflower, endive, and turnips 

 were slightly improved by mulching. Warm season crops were noticeably re- 

 tarded by the mulch, probably due to the reduction in soil temperature. 



The season's studies of premature seeding of celery again showed that moving 

 the plants to a cold frame early was one of the most important factors favoring 

 premature seeding. Of 36 varieties of early sweet corn tested the most promis- 

 ing ones were Early June, Indian, Burbank 86, Early Mayflower, and Early 

 Malcom. Of six varieties of the common dry beans. Red Indian and Yellow 

 Indian matured best. In storage experiments with cabbage, Danish Ballhead, 

 Mammoth Rock Red, and Danish Roundhead stored best. Of 14 varieties of 

 strawberries tested at the home station, Early Ozark, Senator Dunlap, Marshall, 

 and Kellogg Prize passed the winter of 1915-16 very well without protection. 



The results of investigations being carried on at the horticultural substation 

 have been reported in a recent bulletin (E. S. R., 37, p. 241). 



Market gardening {Sta. Agron. Finistere et Lab. Dept. Bui., 1916, pp. 102- 

 124). — Fertilizer experiments with all of the important vegetables grown in 

 the Department of Finistere, France, are here reported. 



Head lettuce for Ohio greenhouses, S. N. Green {Mo. Bui. Ohio 8ta., 2 

 {1917), No. 11, pp. 370-374, figs. 2). — The results are given of a comparative 

 test of leaf and head lettuce conducted in the station greenhouses during the 

 past five or six seasons. 



Leaf lettuce of the Grand Rapids type was found to grow faster and make 

 heavier heads than the head lettuce during the fall months. During the winter 

 months head lettuce matured somewhat quicker and produced about the same 

 weight heads as leaf lettuce. Experience during the past six seasons has shown 

 that varieties of head lettuce may be bred to a degree of disease resistance. 

 Soil sterilization for the control of diseases has proved of considerable value in 

 raising lettuce, but renewal of the soil eveiy year has given the best results. 



In view of the possible overproduction of the loose-leaf Grand Rapids lettuce 

 in Ohio, greenhouse men are advised to experiment with head lettuce and de- 

 velop strains resistant to disease and tipburn. Head lettuce marketed by the 

 station during the winter mouths was sold without difficulty at a good price. 



Growing Bermuda onion seed in the southwestern United States, S. C. 

 Mason {U. S. Dept. Agr., Bur. Plant Indus. [Pub.], 1917, pp. 6, figs. 5).— The 

 author briefly reviews the present status of the Bermuda onion industry in the 

 Southwest and gives an account of experiments in the production of Bermuda 

 onion seed at the Cooperative Testing Station, Sacatan, Ariz. Suggestions are 

 also given relative to the selection of seed stock bulbs, planting, culture, and 

 harvesting the seed. The author concludes that there seems to be no reason 

 why all the American demand should not be supplied with home-grown seed, but 

 that such production should not be undertaken oiitside of limited areas in 

 southern Arizona and California having the requisite mild winter temperature 

 and dry air of the summer season.
