44 EXPEKIMENT STATION EECORD. 



intendea to supply the beau breeder ^Yitll technically accurate iuformation of 

 inuuediate value and service rather than for general distribution. 



Introductory considerations treat briefly of the production of new varieties, 

 synonymy, nomenclature, cultural peculiarities, insect enemies, and diseases of 

 the beau, disease resistance, desirable varieties for various purposes, and 

 system of classification and terms used in descriptions. Lists are also given of 

 desirable varieties for various purposes. 



Notes on mushrooms (Gardening, 11 (1909), No. J/OO, p. 2^8, fig. 1). — In 

 these notes the use of common salt, either sprinkled oh the beds or given in 

 solution in water, is advocated and discussed as a means for keeping up the 

 available supply of moisture in the beds without constant watering, thereby 

 maintaining the quality of the crop over a long picking period. Pouring cold 

 water directly on the beds not only makes the soil mechanically unsuitable for 

 the mycelium to spread, but reduces the temiierature of the bed too much, thus 

 causing the qnality of the product to deteriorate. 



Dewberry growing, O. B. Whipple (Colorado tHa. Bui. 136, pp. 3-8). — A 

 popular discussion of this subject and especially of the following phases : Soils 

 and locations ; propagation; preparation of land for planting; planting; culti- 

 vation; irrigation; fertilizing; pruning; winter protection; picking; packing; 

 varieties; insects and diseases; and yields and returns. A brief cultural note 

 on the Loganberry is also given. 



Breeding apples for Indiana, J. A. Burton (Anier. Breeders' Assoc. Proc., 

 .'i (1908), pp. 'i3, 44)- — "Tlie author has been growing seed from selected apples 

 and from crosses since 1900. Notes are given on a few of these apples which 

 came into bearing in 1907. 



Bud variation in Corinth currant vine, D. McAlpine and F. de Castella 

 (Jour. Dept. Agr. Victoria, 7 (1909), Ao. 3, pp. l^o-l^O, figs. 2). — This consists 

 of a bi'ief account and discussion of a peculiar case of variation in the fruit of 

 the Corinth currant vine, the cause of which is unknown, but which is believed 

 to be a case of bud variation. The variation referred to is that of a bunch of 

 grapes, in which some of the berries resemble Corinth currants, and others 

 Muscat Gordo Blanco grapes, the halves of one berry resembling respectively 

 each of the above-named varieties. 



Citrus culture in the arid Southwest, J. E. Coit (Arizona Sta. Bid. .IS, pp. 

 289-328, figs. 9). — The climatic conditions of the arid Southwest in their relation 

 to citrus culture are discussed and practical suggestions are given for growing 

 citrus fruits, including methods of propagation and planting, stocks for citrus 

 trees, cultivation, irrigation, pruning, picking, and packing. Consideration is 

 also given to the botany of citrus plants, and to diseases and insect pests and 

 their control. 



At the present time less than 1,500 acres in the arid Southwest, including 

 northwestern Sonora. Mexico, are occupied by citrus groves. The Washington 

 navel orange grown in this region is of high color and generally free from 

 smut. It commands high prices. The author warns, however, that " the old 

 idea that citrus culture in Arizona is not endangered by insect pests or plant 

 diseases should be considerably modified, as several such insects and plant 

 diseases are already known." The soils are chiefly in need of a greater humus 

 content. 



[Report on horticulture], J. E. Coit (AtHsona Sta. Rpt. 1908, pp. 3-'il-3.'f6). — 

 Detailed statements are given relative to the condition of the date orchards nt 

 Tempe and Yuma, and at the station farm, together with notes on the cultural 

 experiments with Smyrna figs and an outline of other horticultural investiga- 

 tions for the year.
