but tlie product granulated. Stimulative feeding during the spring 

 was tried, but was interrupted, and the results are inconclusive. 



A non-swarming device was employed with 4 colonies of bees, but 

 proved a ftiilure so far as preventing any desire to swarm. Two strong 

 colonies running together with a non-swarmer produced less comb 

 honey than single colonies tliat were allowed to swarm at will. 



During February and March, 1894, the temperatures of the apiary, 

 of the interior of the hive, and of the outside air were taken and are 

 shown in a table. 



It is urged that the spraying of fruit trees be refrained from while the 

 trees are in bloom to avoid poisoning the bees and in addition affecting 

 the proper fertilization of the blossoms. 



Mosquitoes and fleas, L. O. Howard ( TJ. S. Dept. Agr., Division of 

 Entomology Circular 13^ 2(1 ser., pp. 4). — Mosquitoes. — It is stated that 

 at least 21 species of mosquitoes are present in North America, of 

 which the most common is Giilex pimgens. Observations on the life 

 history indicate that a generation may be completed in 10 days, the 

 Q\^g stage lasting IG hours, the larval stage 7 days, and the pupal stage 

 24 hours, although all of these periods may be lengthened by cool 

 weather. 



For protection against mosquitoes, the use of nets and screens in the 

 windows and doors and about beds and the burning of pyrethrum in 

 rooms to which mosquitoes have gained access are considered the best 

 remedies against the pest indoors, while to prevent their breeding the 

 draining of ponds and marshes, the introduction of fish in lishless 

 ponds, and the use of kerosene on the surface of the water are strongly 

 recommended. Experiments with applying kerosene to pools and 

 ponds show that if an ounce of kerosene be applied to every 15 square 

 feet of water surface the larva^, and pupje in the pool and females 

 alighting to lay their eggs will be killed. The applications should be 

 repeated at intervals of about a month. 



Fleas. — The Ilea causing most common annoyance is Pulex serraticeps, 

 infesting the dog and cat- In case of an outbreak of fleas in the house 

 freely sprinkling pyrethrum powder about the rooms, followed by spray- 

 ing the carpets and floors with benzin, and as a last resort washing 

 the floors with hot soapsuds are recommended as efiflcient remedies. 



Climbing cutworms, M. Y. Slingerland [New York Cornell 8ta. 

 Bill. 104, pp. 553-600, pis. 5, figs. 2). 



Sjinopsls. — This bulletin contains general remarks on cutworms as a class, with 

 additional descriptions and notes on climbing cutworms, and directions for suc- 

 sessfully combating these pests. 



Cutworms in general (pp. 555-5G0). — The habits and appearance of 

 the moths and caterpillars, destructiveness, life history, and natural 

 enemies of cutworms are briefly treated of, and it is stated that about 

 30 species occur in the State. Corn, onions, peach trees, and garden 

 crops in Is'^ew York have suffered most from attacks of cutworms.
