tain methods of culture the same varieties will begin to bloom a few days 

 earlier or later. 



The varieties observed are classified according to time of blooming. A study 

 of the data collected shows that the leading commercial varieties of the section, 

 namely, Ben Davis, Jonathan, Winesap, Grimes, and Mammoth Black Twig, all 

 blossom at about the same period, thus making it possible to secure the greatest 

 benefit of cro.ss-pollination, provided there is mutual affinity between them. 

 Other varieties of less commercial importance also bloom during the same period 

 with the leading varieties, and where bees are kept in or near the orchard the 

 greatest benefit from cross-pollination is assured. 



The apple grading and packing law enacted by the Delaware legislature, 

 1917 (Bui. Bd. Agr. Del, 6 {1911), No. 4, pp. 11-15).— The text of this law, 

 which became effective on June 1, 1917, is here given in full. 



Investigations and experimental work carried on in cherry orchards in 

 Kent during the months of April and May, 1915-16, G. P. Beeby (Jour. Bd. 

 Agr. [Londo7i^, 24 {1911), No. S, pp. 288-298). — Notes are given on varieties of 

 cherries growing in Kent orchards, including information relative to their 

 blooming period and relative sterility or fertility when grown alone and in 

 admixture with other varieties. Some good poUenizers for the Early Rivers 

 variety were determined by actual experiment 



A census of the peach crop of 1917 in West Virginia, compiled by W. H. 

 SoMEus {W. Va. Dept. Agr. Bui. 26 {1911), pp. 24). — This comprises estimates 

 for the 1917 season of the number of baskets of peaches in the various orchards 

 in West Virginia. 



Beport on fertilizer experiments with cranberries, F. P. Schlatter {Proc. 

 Amer. Cranberry Growers' Assoc, 48 {1911), pp. 9-12). — A progress report on 

 cooperative experiments being conducted under the direction of the New Jersey 

 Exi^eriment Stations (K. S. R., 36, p. 641). 



As a result of the work conducted during the past five years the author rec- 

 ommends the use of acid phosphate, rock phosphate, and bone meal for mud 

 bottoms and iron ore bottoms. For sandy or savanna bottoms and possibly for 

 mud bottoms having a heavy coat of sand on top, nitrate of soda, dried blood, 

 cottonseed meal, acid phosphate, basic slag, bone meal, and rock phosphate, 

 either singly or in proper and judicious mixtures, may prove of value. Potash 

 has apparently no value. The use of sulphate of ammonia as a source of nitro- 

 gen is not recommended. 



Spoilage of cranberries after picking, C. L. Shear {Proc. Amer. Cranberry 

 Growers' Assoc., 48 (1911), pp. 6-9). — A paper on this subject outlining the 

 cooperative investigations conducted by the U. S. Department of Agriculture 

 in Massachusetts and New Jersey. The author briefly discusses spoilage due 

 to fungus rots and premature death of the fruit caused by rapid ripening or 

 suffocation. 



First report on cacao selection in Assinan, G. Hombubg and C. J. J. van 

 TT at.t. {Meded. Proefstat. Midden-Java, No. 21 {1911), pp. 1). — A record is given 

 of the yield of parent trees included in the selection study, together with notes 

 on the condition of stock budded from these trees. 



Additional observations on the citrus fruits in the Philippines, P. J. 

 Westeb {Philippine Agr. Rev. [English Ed.'i, 10 {1911), No. 2, pp. 104-115, 

 pis. 7). — In continuation of a previous bulletin on citriculture in the Philippines 

 (E. S. R, 30, p. 644), observations are given on a number of species that have 

 fruited recently at the Lamao Experiment Station, including tabular data show- 

 ing the degree of citrus canker affection in the station collection.
