ENTOMOLOGY, 903 



WinteriiKi expert niciits. — A description is yiveii of the cellar used I'ur 

 winteriiifr and the method of packing, along- with remarks on the cause 

 of dysentery. This is attributed to the bees being so closely confined 

 that they are obliged to retain their feces. When the temperature 

 and other conditions are such that they can go outside of the hives 

 there is little evidence of the trouble. 



As to time for placing in the cellar, the earlier part of November is 

 preferred to the latter part. Summarizing briefly the results of experi- 

 ments with 37 colonies, it is stated that "the average strength of the 

 entire lot of 37 colonies was 6.59, average fall weight 53.52 lbs., average 

 spring weight 42.20 lbs., average consumption 11,32 lbs., average con- 

 sumption per unit of strength 1.72 lbs.'' 



The experiments in spring packing resulted favorably to the process 

 and showed that there was an increase in weight and the production 

 of a large am<»unt of brood. 



In conclusion the economy of the hive is briefly treated, including 

 the building of the comb, the rearing of young bees and of <iueens. and 

 the laying of eggs. 



Report of the entomologist, J. B. Smith {Xeu- Jersey tStas. Ept. 

 1895, pp. o65—j.L^ij, Jigs. sO). — Besides a general review ot the season, 

 miscellaneous information is given on aaiumber of different insects. 



Geyieral review of the season, (pp. 36.5-112). — There are treated, in a 

 general way, cutworms, the sinuate pear borer, jiear midge, bagworm, 

 potato beetle, San Jose scale and other scales, elm leaf beetle, maple 

 pseudococcus, the fall webworm, the fruit bark beetle, plant lice, potato 

 stalk borer, cranberry insect, wire worm, and white grubs, and a section 

 is added on the subject of insecticides. In the latter section the author 

 summarizes the results of his experience, and among other things states 

 that arsenate of lead must be used in larger proportion than other 

 arsenical poisons, but that when used at the rate of 2 lbs. to 100 gal. 

 of water it may be employed with entire safety to the plant, and as an 

 insecticide will then equal Paris green, or London purple used at the 

 rate of 1 lb. to 125 gal. Although thus used it is rather more expen- 

 sive than Paris green, it has some advantages over the latter. Potato 

 Bug Exterminator Compound was not found to fulfill the claims made 

 for it. Fir Tree C)il Soap was found ineflflcieut in killing scales in any 

 strength in which it could l)e used. 



Referring to the sinuate pear borer, the author says that instead of 

 Kaupenleim or Dendrolene, canvas or some equivalent fabric which the 

 insects can not eat through may be used on the trunks and larger 

 branches of trees. Ileavy paper wrapped about the tree, lie thinks, 

 would probably serve the purpose eciually well, or the trunks of the 

 trees might be smeared with some material that would harden and 

 form a coat impenetrable to the insects. 



As an insecticide for scale insects he prefers whale-oil soap to fish- 

 oil soap as being considerably cheaper. As a remedy for the elm leaf
