 premises, ola wooden henhouses be pulled down and corrugated iron buildings be 

 erected in their place. 



Bee culture, C. C. Miller { Pemi.vjlvania Dept. Agr. Rpf. 1901, pt. 1, j^p- 334-427, 

 Jiffs. 14). — This article constitutes a general treatise of a practical nature covering all 

 of the subjects ordinarily included under apiculture. Among the various subjects 

 treated in the article, mention may be made of fertilization of flowers by bees, loca- 

 tions for colonies, kinds of honey, honeycomb, hives, different varieties of bees, 

 apparatus for use in managing bees, artificial feeding, comb foundation, clipping 

 queens, extracting honey, prevention of swarming, rearing of queens, division of 

 swarms, enemies and diseases of bees, care in winter, and a brief discussion of the 

 more important literature relating to bees. 



Practical bee keeping, A. E. Manum {Rhode Idand State Bd. Agr. Rpt. 1901, pp. 

 218-,i31'). — Brief notes are given on the selection of hives and frames, as well as on 

 the spring management, preparation for summer harvest, spring dwindling, stimula- 

 tive feeding, and notes on wintering and putting on section boxes. 



Long-tongued bees, A. Gale {Agr. Gaz. New South Wales, 13 {1902), No. 2, pp. 

 233-235). — The author presents a brief digest of the literature on the subject of 

 breeding bees so as to secure an elongation of the tongue. This subject is considered 

 of some importance for New South Wales on account of the fact that heretofore it 

 has been found inip()ssil)le to introduce Innnblebees for the purpose of fertilizing red 

 clover. The possibility of securing a honeybee with a tongue of sufficient length to 

 obtain honey from these flowers is worth considering for the reason that such honey- 

 bees would lie induced to visit the red clover and thus fertilize it. 



The embryology of the silkworm, K. Tovama {Bid. Col. Agr. Imp. Vnir. Tokyo, 

 5 {1902), No. l,pp. 73-118, pis. 5, fig. 1). — The author discusses the literature relating 

 to the early developmental stages of the silkworm, in connection with an extensive 

 bibliography. The discussicn is confined largely to a description of the early stages 

 of development, with special regard to indicating the origin of the various embryonic 

 organs of silkworms. 



Healthy and diseased silkworms, H. Ecjidio {Sfaz. Sper. Agr. Ital., 35 {1902), 

 No. 1, pp. 35-45). — The author made a careful analysis of the excrement and con- 

 tents of the alimentary tract of healthy and diseased silkworms, in order to determine 

 whether the presence of uric acid or urea should be considered as indicating a dis- 

 eased condition. It was found that in the excrement of healthy silkworms no uric 

 acid, hippuric acid, or urea was to be found. 



FOODS— NUTEITION. 



Cereal breakfast foods, L. H. Merrill and E. R. Mansfield {Maine Sta. Bui. 

 84, pp. 129-152). — Continuing the investigations reported in an earlier bulletin (E. 

 S. R., 12, p. 69), the authors studied the composition and nutritive value in proportion 

 to the cost of a number of cereal breakfast foods. In the case of malted cereal goods 

 and some others the methods of manufacture are briefly discussed. The average 

 percentage composition of the corn, oat, and wheat breakfast foods, which constitute 

 the larger proportion of the foods examined, follows:
