The specific weight of fruit varieties, II. Zimmkkman ( (InrtniicrU, IS (1909), 

 .\o. J, /*/'. .i'.t-'tl). — Tlu' author, having tt'stt'd the vahie of the si>ecific pravity 

 of ai»i»les n.s a means of (lelerniiniiiK varieties, in accordance with the method 

 noted (see p. 103")), arrives at the conclnsioii tiiat the si»ecific densities of vari- 

 ous heavy fruits of the same Aariely arc not snlliclently constant to be used as 

 n distinfinlslilnj? character. 



In order to determine wlictlier tlie differences in the size of the air spaces in 

 the core influence the specific wei^dit, several apples were (piartered and the core 

 removed. The specific density was then determined for each quarter. From 

 th(> data secured it is concluded that the siiecific density is not affected by the 

 air spaces In the core, but is influenced by the general structure and composition 

 of the api)le. 



Papers read at the summer meeting of the Ohio State Horticultural Society 

 {Ohio fita. Circ. 81, pp. 13). — This circular contains the full text of the various 

 r.ddresses and papers delivered at the summer meeting of the Ohio State Horti- 

 cultural Society, as follows: Orchard Renewal, by S. R. Gill; Spraying for 

 Apple Scab in 190S, and Proposed Spray Mixtures for Orchard Use, by A. D. 

 Selby : two papers on Control of I'ear Blight in Northern Ohio, by R. A. Hunt 

 and W. Miller, respectively; and Experimental Notes of the Season, by H. A. 

 (Jossanl. The last-named paper deals with spraying experiments with fruit 

 trees.

 some {London, 1908, pp. 83, pis. //, figs. 27). — A popular work on this subject in 

 which the author discusses the principles involved in intensive French vegetable 

 gardening, and gives the history of French gardens in England, together with 

 the details of the equipment required for such work, and its cost. 



Sugar corn and tomatoes, T. 11. ]McHatton {Georffia t<fn. Bui. 82, pp. 175-207, 

 flgs. I'l). — The station inaugurated in 1908 a series of culture experiments to 

 determine the possibilities of growing the ordinary vegetables under (Jeorgia 

 conditions. Sugar corn and tomatoes were the crops tested during the past 

 season. This bulletin contains an account of the experiments, including the 

 notes and data secured. It is stated that the work has not been continued 

 sufflciently long to warrant definite conclusions. 



In the work with sweet corn special study was made of the relation between 

 the time of planting and the subsequent crop, as indicated by the yield, sugar 

 content, percentage of smut, and injury by corn ear-worm. Five varieties were 

 grown and plantings were made one week apart from May 6 to June lo, 

 inclusive. Different varieties behaved differently, but the results as a whole 

 for the season, which was an unusually dry one, indicate the third week i :i 

 May is the best time for planting sugar corn. Smut and the corn ear-worm 

 were the prevalent troubles, the smut affecting from 2.33 per cent to 37.57 

 per cent of the crop and the corn ear-worm from G0.7 per cent to 100 per cent 

 of the crop. The early plantings were injured most by smut and the late 

 plantings by the corn ear-worm. 



In the tomato work a comparative test was made of barnyard manure, acid 

 phosphate, muriate of potash, nitrate of .soda, and a complete chemical fertilizer, 

 relative to their influence on the yield and quality of the crop. A test was also 

 made of the mulched, unmulched, and staked systems of culture. The results 

 for in08 indicate that either barnyard manure or a complete chemical fertilizer 

 gives better yields than any of the chemicals used alone. The acid phosjjhate 

 plat showed the smallest percentage of diseased plants, and the nitrate of 

 soda plat the highest. The complete fertilizer plat gave the best quality fruit, 

 followed by that fertilized with nitrate of soda. The best yields were secured
