 to withstand this treatment." 



Manuring- of fruit trees, A. Petts (Jour. Hort., 53 {1901), Xo. 2745, pp. 388, 

 38!)). — The best methods of using potash and liquid manures on fruit trees are noted. 



Cold storage for fruit and other productions, F. R. Latchford ( Ontnrio Fruit 

 Growers' A><soc. Itpt. 1900, pp. 81-89). — A popular discussion of the subject, in which 

 the value of the Hanrahan system of cold storage is pointed out. 



Storage of apples, H. H. Lamson {Ne^o Hampshire Sta. Bui. 79, p>p. 25-29). — The 

 decay of the Baldwin apple was found to be due chiefly to brown rot and the com- 

 mon mold fungus [Femcillium glaucinn) . While these fungi are widely distributed, 

 it is believed that apples barreled in the orchard will be less likely to be infected 

 than if they are previously stored uncovered in dusty barns or moldy cellars. Heat 

 and moisture are especially favorable to the growth of rot-producing fungi. Hence 

 the value of storing apples in a dry, cool place. 



In order to test the value of cold storage for apples, 12 bushel boxes of No. 1 Bald- 

 wins were put in cold storage, in Boston, where the temperature averaged about 

 34° F., and a check kept in the station cellar. The station cellar averaged about 

 40° until April, then ran up to 45° during the first half of the month and 

 to nearly 50° during the latter half. Part of the stored fruit was wrapped with 

 manila tissue paper in each case. One box was withdrawn from cold storage each 

 month until June, after which date 2 were withdrawn each month until the 12 had 

 been exhausted. The amount of sound and rotten fruit in the Ijoxes for each of the 

 months December 18 to August 4 is shown in tabular form. While in general there 

 was an increase in the number of rotten apples as the season advanced, this increase 

 was not at all uniform, and no explanation of this phenomenon is offered. In all but 

 two instances the wrapped apples kept better than the unwrapped. 



Apples in Iowa {Rpt. Iowa Hort. Soc, 35 {1900), pp. 55-72, maps 12). — From 150 

 answers to a circular letter of inquiry the secretary of the society has compiled a list 

 of apples that may be grown with assurance all over the State of Iowa. These are 

 Oldenburg, Yellow Transparent, Longfield, Tetofsky, Red Astrachan, Plumb Cider, 

 Walbridge, Wealthy, Wolf River, and one crab — Whitney No. 20. Of these varieties 

 6 are summer apples, 3 fall apples, and only 1 — the Walbridge— a long keeping winter 

 apple. The areas where these and some other varieties thrive best are mapped out 

 for the State. 



Apple districts of "West Virginia, L. C. Corbett ( ^yest Virt/ltiia Sia. Bui. 75, pp. 

 83-178, figs. 13, map 1) . — Preliminary notes are given on the apple orchards and 

 apple crops of West Virginia and on top-grafting old trees. Following the severe 

 freeze of March 29, 1898, an inquiry was made of special correspondents in each 

 county of the State as to the condition of orchards, the purpose being to learn in 

 what districts commercial fruit growing can be engaged in with a fair assurance that 

 the crop will not be injured by any ordinary late spring frost. A map based on these 

 replies is given which shows graphically the various localities where full and where 

 only partial crops were reported. Another map shows graphically the areas in West 

 Virginia reported as suited to apple culture, areas suggested as valuable for this pur- 

 pose, and the areas where commercial orchards are now growing. 



The relative values of 114 varieties of apples and 5 varieties of crab apples, as 

 shown by nearly 2,000 answers to a circular letter of inquiry, for each county of the 

 State, are brought together in a comparative table. Further separate tables are 

 also given for each county of the State showing the varieties of table apples held in 

 highest esteem in the county; the market varieties having the best form, color, and 

 keeping qualities; varieties which keep in pits or cellars in fit condition for the April 

 market; varieties which bear most regularly; varieties most exempt from or most
