56 EXPERIMENT STATION RECORD. 



a frilled appearance, and may extend up the stem for a distance of 6 in. to a 

 foot or more. When badly attacked the plants frequently are destroyed. 



Violet root rot {Jour. Bd. Agr. [London], 12 (1906), No. 11, pp. 667, 668, 

 pi. 1). — Tbe author briefly describes the disease due to Rhizoctonia violucca, a 

 fungus which attacks alfalfa, clover, carrots, beets, mangels, and potatoes. On 

 account of the wide range of host plants, care must be exercised iu rotation ex- 

 periments, and injury due to the fungus may be prevented to a considerable 

 extent by iiniiun- rotations, drainage, culture, and seed selection. 



Broom rape on pelargonium, P.. D. Malsted, E. J. Owen, and J. K. Shaw 

 (New Jerscij Htaa. Rpt. 1905, p. 509, pi. 1). — An account is given of the attack 

 by one of the broom rapes (Orohanchc minor) on i)elargoniuras growing in the 

 greenhouse at the station. The author also notes the occurrence of 0. rumosa 

 on tomato plants under the same coftditions. 



Spraying' m.ixtures, W. E. Bear {Jour. Bd. Af/r. \Loudou], 12 {1906), No. 11, 

 pp. 660-666). — The author calls attention to the unsuitability of some fungicides 

 for general use, and states that the spraying of fruit trees and bushes is at pres- 

 ent in an empirical stage. He suggests that experiments should be carried on 

 to put the practice on a more satisfactory basis. These would include investi- 

 gations on the effective strength of solutions, importance of purity of materials, 

 and the proper times for spra.ving. 



A method for the determination of the fineness of sulphur used as a 

 fungicide, V. Dussekre {Aim. Af/r. ;S'»/,s.s'C, 6' {1905). No. 9, pp. •IS.3-,3S7). — For 

 the rapid determination of the fineness of sulphur to be used in combating the 

 powdery mildew of the grape the author recommends an adaptation of the 

 Schone soil elutriator, and gives the results of a number of tests of this ap- 

 paratus, comparing the results with those obtained by other methods. 



ECONOMIC ZOOLOGY ENTOMOLOGY. 



International catalogue of scientific literature- N — Zoology {Intcrnat. 

 Cat. .S'c/. Lit.. 1905. pts. 1, pp. VIII+'i32: 2. pp. A/+,96-J).— The third annual 

 issue of the literature on zoology is divided into 3 parts, of which the first part 

 contains a general account of the system pursued in classifying zoological 

 literature and an author index on literature published since 1V)01, but particu- 

 larly for the year 1903. I'art 2 contains a subject index of literature relating 

 to invertebrate animals. 



The night hawk, A. Meraz {Com. Par. Agr. [Mccico], Circ. J/0, pp. 4, pg. 1). — 

 The h.-ibits of this bird are I)riefiy discussed with particular reference to its 

 agricultural imiiortance. The night hawk is almost strictly insectivorous and 

 a large proportion of the insects upon which it feeds is injurious. In an exam- 

 ination of 87 stomachs of night hawks, 20,000 ants were found in addition to 

 various other insects. 



Birds that eat the cotton-boll weevil, A. II. Howell {U. *S'. Dcpt. Agr., Bur. 

 Biol. Siirrcg Bui. 25, pp. 22). — Observations on l)irds in the region where the 

 cotton-boll weevil prevailed in 1905 have added somewhat to the list of those 

 known to feed upon this pest. At present 28 species are recorded as feeding 

 upon the cotton-boll weevil to some extent and part of them in summer and 

 others during the winter months. Notes are given on the importance of various 

 birds iu this work, including orioles, blackbirds, meadow lark, night hawks, 

 sparrows, fly catchers, quail, etc. Details of observations at different points 

 are also presented together with a tabulation of the results obtained by the 

 examination of birds' stomachs.
