Black check in western hemlock, II. E. Burke I U. S. Dept Agr., Bur. Enl. 

 Ore. 61, />/>. 10, figs. 5). — Black check is a defeel of western hemlock doe to the 

 attack of a bark beetle I Hylesmus n. Bp. I, in the burrows "t' which a bark maggot 

 (Cheilosia alaskensis) penetrates and increases the injury. < >n low land a large per- 

 centage <>!' the wood is thus rendered worthless for finishing, Btaves, or woodenware. 

 < \ hoodianw causes a similar injury to Abies grandis. In order to avoid getting lum- 

 ber with this defect, it issuggested that trees he selected from altitudes of 1,800 ft. or 

 more. 



The felted beech coccus, R. Newstead (Jour. Bd. Agr. [London], 11 i 1905), \<>. 

 19, i>i>. 755-760, figs. 7). — Qryptococcus fagi confines its attacks to the beech and is 

 considered one of the most destructive pests which attacks this tree. It occurs gen- 

 erally in England and in some parts of Scotland. The insect is described and notes 

 are given on its lite history. It may usually be controlled by spraying with kerosene 



emulsion with or without the additi >f sulphur and turpentine or by treatment 



with caustic-alkali wash. 



The chief injurious scale insects of Connecticut, \V. E. Britton (Connecticut 

 si.ii, s/,i. Bui. 151, pp. 16, figs. 17). — The more important scale insects of Connecticut 

 are described and arranged in a convenient manner for identification. In this mate 



ner the author discusses 29 species including elm scale, cottony maple scale, tulip 



scale, oleander scale, San Jose" scale, oyster-shell scale, etc. 



Spraying- for scale insects, II. .1. Quayle ( California Shi. Bui. 166, pp. ?4, figs, 

 t). — Spraying experiments were conducted against the brown apricot scale and San 

 Jos,', scale. 



Lime-sulphur-salt wash was tested in various formulas. Lime, sulphur, and salt 

 were used at the rate of 40, 20, and 15 lbs., respectively, for each 60 to 120 gals, of 

 water. All dilutions up to 90 gals, of water were effective. In another set of tests 

 the amount of lime for each 60 gals, of water varied from 20 to 50 lhs. All combina- 

 tions were effective, hut a Blight excess of lime seemed to be beneficial. In other 

 experiments the amount of sulphur ranged from 5 to 40 lbs. Solutions containing 

 small amounts of sulphur were less efficient. The author is not prepared to recom- 

 mend the disuse of salt. Copper sulphate used to replace salt removed the moss 

 from trees hut otherwise had no advantage. 



In general the lime-sulphur-salt wash proved effective against San Jose scale, but 

 not against the brown apricot scale. It should he used chiefly on dormant trees. 

 Preparation of the wash without boiling does not reduce the cost. Resin wash was 

 satisfactory for brown apricot scale but not for San Jose scale. It should be applied 

 in January and February. Patent compounds have no advantages over standard 

 remedies. The standard 3 percent distillate insecticide was not very effective against 

 the brown apricot scale. 



Insects injurious to roses, P. Lesne (Rev. Hort. [Part*], 77 (1905), No. ?, pp. 

 167-170, ]>I. 1). — Descriptive, economic, and biological notes are given on a number 

 of rose pests, including gypsy moth, brown-tailed moth, rose scale, Cladius pectini- 

 cor a is, etc. 



Insecticides and fungicides, K. Harcourt (.1////. Rpt. Ontario Agr. Col. and 

 ExjiI. Form, SO (1904), pp. 68, 64)' — Brief notes are given on the preparation of 

 lime-sulphur washes and an analysis of fungeroid is reported.

 j 1904 \, /'/'■ 54-60). — Milling tests were made with ten samples of different grades of 

 wheat grown near Winnipeg, as well as studies of the moisture and proteids and
