The salt-marsh mosquito ( Culex sollicitans), J. B. Smith {Xeiv JerHc.ij tSlax. 

 Spec. Bui. T, pp. 10, figx. 2). — -The author gives brief notes on the habits and life 

 history of this species of mosquito, which is considered one of the worst pests along 

 the coast line. This species breeds in salt or brackish water, or occasional!}- in fresh 

 water fields on salt marshes. The author never ol)served the species breeding 

 in inland fresh water. The life history of this species of mosquito is not well 

 understood. It probably passes the winter in the egg stage. The remedies whicl^ 

 are suggested for mitigating the mosquito plague include the drainage of pools of 

 stagnant water, and application of kerosene to small areas where this method would 

 lie more convenient than drainage. One peculiarity of the salt-marsh mos(inito is 

 noted, and consists in its habit of drifting with the wind to great distances frcnu its 

 breeding grounds. It may at times, therefore, cause annoyance in localities where 

 no stagnant ponds are found. 



The mag-g-ot fly, (". Fillkk (A(jr. .four. Cape Good Hope, 20 {1902), Xo. 2, 

 pjj. 102-10.5). — This is a ])rief account reprinted from the Natal Agricultural,] ournal 

 concerning the attacks of Auchmeroyia depres.m upon dogs and man. Notes are given 

 on the appearance of the insect in its different stages and upon its life history and 

 habits. It is somewhat common in A'arious parts of South Africa. 



The distance apart at which apiaries should be placed, De Soignie (.lour. 

 Soc. Cent. Agr., Belg., 49 {1902), No. 6, pp. 267, 268).— The author discusses the 

 various legal regulations which have been made for determining the localities for 

 placing apiaries, the distance from public dwellings and thoroughfares, and various 

 other devices which are to he adopted in iireventing apiaries from causing annoyance 

 to the public. 



The relationship of honey to wax, C. l\ Dad.\nt {Rev. Intcrnat. Apicnlt., 24 

 {1902), No. 4, pp. 68-71). — A general discussion is presented on the question <if the 

 expensiveness of the manufacture of wax by bees. The author believes that the 

 pro(hiction of wax from honey by the bees is too expensive and should not be jier- 

 mitted to occur. Foundations of greater or less size will prevent to a large extent 

 the use of honey for the manufacture of wax. 



Do bees injure fruit? {Queensland Agr. Jour., 10 {1902), No. 2, pp. 107, 108). — 

 A l)rief discussion of i)OSsibIe injury to grapes ])y honeybees. It is urged that the 

 mouth parts of bees are well adapted to biting fruits, Iwt that according to common 

 exjierience they rarely cause any damage of this sort. 



Sericulture, J. Bolle {Ztschr. Landw. Versuchsiu. Oesterr., 5 {1002), No. 3, pp. 

 475-480). — Experiments were made in crossing different races of silkworms for the 

 purpose of determining whether larger cocoons, with silk more easily reeled, could 

 be produced. For a considerable length of time the results in cro.ssing races were 

 unsatisfactory; many undesirable characters which belonged to the different races 

 reappeared from time to time in the crosses. Even when the desire<l characters were 

 produced, they seemed to l)e obtained at the expense of the vitality of the silkworms. 

 After a long series of experiments some results were obtained which indicate the 

 possibility of improving the character of the silk and the size of the cocoon without 

 losing the vigor of the worms at the same time. It is recommended that until 

 improved races shall show themselves as being constant m character it would be best 

 to continue with the old well-known races. 



The author made some experiments with micro-organisms which were found in the 

 alimentary tract of silkworms infected with flaccidity. It was found possible to 

 inoculate healthy silkworms with organisms which were ol)tained from infected 

 worms, but it is not considered that the causal connection ot these organisms with 

 the disease has been definitely proved. In localities where jaundice of sdkworms
