900 EXPERIMENT STATION RECORD. 



The illustrations of this work, most of which are very well executed, are given 

 to illustrate pathological objects rather thau to give drawings of microscopical sub- 

 jects, the author considering it more essential in this Avork to show the eftect of the 

 fungus uiiou the host. Some of the illustrations are from the older works, hut most 

 of them are from drawings and photographs made by the author. 



In tiiis edition certain portions have been entirely rewritten from the original 

 edition, which appeared in 1894. As has already been stated, the editor has in^uded 

 many references to comparatively recent literature. 



In the discussion of pathogenic bacteria one very important contribution to the 

 subject seems to have been overlooked, namely, that of E. F. Smith on the wilt of 

 Cucurbits, which is due to Bacillus iracheij)hHiis, OT\gina,\ly published in the Central- 

 hldttfiir Bakieroloijie and Parasitenkunde, AlUj., 1 (1895), p. S64. 



A few other omissions of American literature which may not have been available 

 to the editor are noticed, but the great value of the work is not seriously imjiaired 

 by their absence. 



On the whole, it Avill proljably be fouml the most recent and valuable work ou 

 this subject in the English language. 



ENTOMOLOGY. 



The apiary: Report for year ending June 30, 1895, E. L. Taylor, 



{Mich iijan l^ta. Rpt. 1S95, pj). lsG-22o]. — The author gives liere tlie results 

 of experiments relating to (1) spring protection and stimulative feed- 

 ing, (2) comb foundation, (3) foul brood, (4) feeding back, (5) the pre- 

 vention and management of swarming, (G) Conser's non-swarming hive, 

 (7) wintering, (8) spring packing, and (9) a general discussion of the 

 economy of the liive. 



Spring protection and stimulative feeding. — The experiments were 

 begun with upward of 80 hives, but owing to losses and other circum- 

 stances, the number was reduced to 01. Of these 9 two-story and ]2 

 one-story Heddon hives, ou April 10 were packed with sawdust, so that 

 there was a layer of 2 to 3 in. in front, 3 in. on top, and 4 in, on the back. 

 Where 2 hives Avere adjacent, the intervening .space was simply filled up. 

 Finally the hives were divided into 2 classes: (I) Those requiring 2 sec- 

 tions of the Heddon hive, and (2) those for which 1 section would be 

 sufficient. 



Feeding was begun at the close of the apple blossom season (May 20) 

 and continued until June 10. One pound of thin sirup (made of 1 lb. 

 sugar and 2 lbs. water) was fed daily at the entrance in Simplicity feed- 

 ers, when the bees would take that much. The amount taken seemed 

 to depend upon the weather. 



Contrary to what had been expected, no great advantage was found 

 to result from such protective treatment. In every way the uni)acked 

 colonies excelled the others in the increase of stored honey and in 

 weight. Stimulative feeding resulted advantageously to a trifling 

 extent in three instances and disadvantageously in a fourth instance. 



In connection with these results the author brings out the fact that
