60 HORTICULTURE [Box. Absts., Vol. VIII, 



were selected for northern propagation. Iowa has a climate which is colder than that of the 

 same latitude farther east, and pecan trees there are hardier and have to mature fruit in a 

 shorter season. These considerations are important in selecting varieties for northern plant- 

 ing. — E. L. Ovcrholser. 



389. Lewis, C. I. Sites and soils for small fruits in the Northwest. Better Fruit 15^: 6, 

 17-18. 1920. — Adaptation of the various sections and localities of the Northwest to the 

 commercial cultivation of the different varieties of small fruits is considered in detail. A 

 rather heavy soil and fairly humid climatic conditions are of particular importance to the 

 successful growing of almost all small fruits, the strawberry being a marked exception in this 

 respect. — A. E. Murneek.

 einiger Reisigarten. [Concerning the composition, in particular the starch content, of certain 

 kinds of prunings.] Landw. Jahrb. 35:585-615. 1919. — The author calls attention to the 

 possible value as fodder of the prunings from vines, fruit trees, and from certain shade trees. 

 Twigs collected in December were studied with reference to general chemical composition, 

 and microscopically to determine relative starch content and lignification of walls. The 

 following species were used: Acer platanoides, A. pseudoplatanus, A. negundo, Aesculus 

 hippocastanum, Betula verrucosa, Populus virginiana, Pirus communis, P. malus, Tilia platy- 

 phyllos, Ulmus campestris, and Vitis vinifera. The estimated starch content was least in 

 Betula verrucosa and greatest in Vitis vinifera. The relative lignification of the cell walls 

 was least in Tilia platyphyllos and greatest in Ulmus. The paper is accompanied by several 

 plates showing photomicrographs of cross sections and starch grains in various species. —

393. Patterson, J. H. Cost and development of pecan unit orchards. Amer. Nut Jour, 

 13 : 36. 1920. — The ideal development of a pecan orchard requires rich soil enriched each 

 year by ploughing under legumes. Under these conditions the orchard will yield a paying 

 crop in 10 years. — E. L. Overholser. 



394. Pearcy, K. Timely notes on Oregon nut growing. Better Fruit 15^: 12, 24. 1920. — 

 A general discussion is presented on filbert growing in Oregon. Varietal differences are em- 

 phasized. Some of the main commercial varieties appear to be self-sterile. Investigations 

 conducted at present by the Oregon Agric. Exp. Sta. may throw some light on the pollination 

 problem in the filbert. — A. E. Murneek. 



395. Ramsey, F. T. Some of the older varieties of pecans of Texas origin. Amer. Nut 

 Jour. 13 : 67-68. 1920. — Reviews are presented of the important varieties, giving dominant 

 characteristics. Instances are cited to show that varieties from the arid western regions 

 when grown farther east under more humid atmospheric conditions decline, both as to health 

 of the trees and size and plumpness of the nuts. — E. L. Overholser. 



396. Rasmussen, P. M. Pecans in California. Amer. Nut Jour. 12: 30. 1920.— The best 

 nuts of Fresno County are grown at Selma, which is also a promising district for the walnut 

 and almond. — E. L. Overholser. 



397. Read, F. W. The new shipping-point inspection service on fruits and vegetables. 

 Monthly Bull. Dept. Agric. California 9:371-374. 1920.— The inspection work is being 

 undertaken by the Standardization Service at terminal marketing points. A certificate of 

 inspection is issued which includes details of car storage and condition and quality of pack 

 and fruit. The certificate is receivable as prima-facie evidence in the courts of the State. —
