 Gesell., 76 (1S9S), Xo. 3, pp. 63-70, pi. 1). — The author calls attention to a common 

 Microspbsera on Syringa in this country which seems to have been mistaken for

The carnation fairy ring fungus, B. D. Halsted (Amer. Florist, 13 {1898), Xo. 520, 

 p. 1256, fig. 7). — This disease is attributed to attacks of ffeterosporium echinulatum.

Specimens of diseased plants, etc., F. T. Bioletti ( California Sta. Bpt. 1895-1897, 

 pp. 2S7-242,pl. l,fig. 7). — Notes are given on a number of diseased plants which were 

 sent in for identification. The cause of the trouble in each case is given and sugges- 

 tions offered in many cases for the prevention of the disease. One of the most serious 

 diseases reported upon is the tuberculosis of olives, which has been reported upon in 

 Bulletin 120 of the station (E. S. R., 10, p. 55). 



Literature of fungus diseases, W. C. Sturgis (Connecticut State Sta. Bpt. 1897, pp. 

 182-222). — A provisional bibliography of the more important works published by 

 the U. S. Department of Agriculture and various agricultural experiment stations of 

 the United States from 1887 to 1897, inclusive, on fungus and bacterial diseases of 

 economic plants. The general arrangement of the subject is as follows: The host 

 plants are arranged alphabetically, and under the name of each host plant are also 

 arranged alphabetically the common names of the fungus diseases recorded as affect- 

 ing that plant References to descriptions and illustrations either of the fungus 

 itself or of its effect upon the host plant follow, and finally suggestions for treatment 

 if any have been recommended The author has devoted considerable study to the 

 subject, and has listed only those publications which he is convinced give the best 

 descriptions, illustrations, or treatments which have been tested. 



In addition to the bibliography outlined in the preliminary paragraph, a bibliog- 

 raphy of 100 publications (mostly foreign) relating to plant disease is given.

 pp. 213-233). — The author popularly describes injurious fungi and insects and sug- 

 gests remedies for the prevention of their attacks. Numerous fungicides and insect- 

 icides are described and formulas given for their preparation. 



Notes on the preparation of fungicides, L. Degrully (Prog. Agr. et Fit., 29 

 (1898), Xo 19, pp. 577-581). — Formulas are given for the preparation of a number 

 of the better known and most efficient fungicides and explicit directions for their

Report of the apiculturist, R. F. Holtermann ( Ontario Agr. Col. 

 and Expt. Farm Rpt. 1897, pp. 235-244, Jigs. 3).— The report is of a 

 miscellaneous nature, the more interesting facts of which are the suc- 

 cess in the plan of cutting the combs of the brood chamber, thus allow- 

 ing of ready communication between the different parts of the clustering 

 swarm, as described in the last report; the confirmation of experiments 

 on foul brood made during the previous year, demonstrating that the 

 germs are completely destroyed by the process of foundation making; 

 the failure of Oarniolans to produce satisfactory combs unless given 

 full sheets of foundation ; the fact that in healthy cellar wintering there 

 is no brood rearing, and that stores in the brood chamber may be moved 

 to the supers to such an extent as to greatly injure the quality of the 

 honey in the latter.
