268 EXPERIMENT STATION RECORD. 



All experiment is noted on the value of pure air ventilation and arti- 

 ficial heat in wintering. A cellar was partitioned off into four rooms, 

 at the end of one of which was placed a stove, the pipe from which ran 

 through all four rooms. The temperature on February 14 of room 1 

 was 38° F., rooms 2 and 3, 40°, and room 4, 42°. The bees in the first 

 cellar were much the most quiet. In the. last they were the most rest- 

 less all through the winter. The whole of the 300 colonies, with the 

 exception of several starved and mice-destroyed colonies, all came 

 through successfully. Although the passage of air from room to room 

 is not desirable, the beneficial feature of currents of pure air and the 

 maintenance of a steady low temperature is demonstrated. 



Other subjects noted are the superiority of a bee space between sec- 

 tions in supers; the success of moving bees to fall pasture; the im- 

 portance of filling sections to sides and bottom with foundation, thus 

 preventing the formation of pop holes; and the superiority of founda- 

 tion running 12 ft. to the pound over thinner kinds, since in the latter 

 the bees show a tendency to cut holes. 



Report of the department of entomology, V. H. Lowe and F. 

 A. Sirrine [New York State Sta. Rpt. 1X96, pp. 522-635, ph. 25). — The 

 report is divided into two parts; the first by V. H. Lowe, the second 

 by F. A. Sirriue. After an introduction by the former, in which the 

 principal lines of work are explained and the number of specimens 

 in the station collection and the objects of the collection noted, the 

 more important of various insects and their ravages are discussed. 



Some of the more important injurious insects of the year (pp. 525- 

 535). — Under this head there are noted the locusts {Melauoplus femor- 

 atus, M. femur-rubrum, and M. atlanis); striped cucumber beetles, the 

 injuries of which have been of considerable importance in the western 

 part of the State; asparagds beetles {Crioceris asparagi and C. 12- 

 punctatus); aphids (Myzus ribis and Rhopalosiphum rihis), over 50 per 

 cent of the former being noted as destroyed by parasites and spiders; 

 red spider ( Tetranyehus telarius), which injuriously affected the rasp- 

 berry bushes in Ulster County, New York, where they were shaded by 

 trees, and also seriously injured currant bushes; chinch bug, (Blissus 

 leucopterus), Putnam scale (Aspidiotus ancylus), and oyster-shell bark 

 louse {Mytilaspis pomorum). The latter is not satisfactorily destroyed 

 by kerosene emulsion unless the trunk is first well scraped and the 

 emulsion applied in full strength with a stiff brush. Cankerworms 

 were more abundant than during the previous year, mainly on account 

 of remedial measures not being taken early enough nor continued with 

 sufficient thoroughness. 



Experiments with green arsenite (pp. 536-539). — Several experiments 

 are noted with green arsenite or Sheele's green, which resulted in 

 showing that the green arseuite will remain suspended in water for a 

 longer time than Paris green, aud hence can be applied more evenly to 

 the foliage and requires less stirring in the tank, and that it will not
