remedies are suggested for its repression or destruction. The obser- 

 vations and conclusions in this bulletin should be compared with 

 those from independent sources, recorded in Insect Life, Vol. IT, No. 

 4 (pp. 93-103) and No. 6 (p. 165). The following is a popular de- 

 scription of the Hy as given by Professor Smitli : 



Hiniiatfihid srrnila. K. Dosv. — The Hy is iiltout 4""". or nitlior more than one- 

 sixth of an inch in Icniilh. of a darlc. asli-gray color, with a faint yellowish 

 ringe. To tlio ordinary observer they ajipoar nearly black, and are generally so 

 dcscrilicd in tlie letters received. The head is almost entirely taken up by the 

 eyes, which are dai-k-red brown, deeper in color than that of the common house 

 fly. The eyes are margined in tlic front by a narrow lino of silvery white pile; 

 the front is darker, and along each of the white borders is a row of long bristles 

 curving over the front. The antenuie are small, two jointed, with a long pecti- 

 nated or feathered bristle to the second joint. Below the antenniP can be seen 

 the proboscis, usually carried straight forward and projecting a little in front 

 of the head ; accompanying this are the unusually long palpi, which are rather 

 densely set with shoi't, stiff hair. On the top of the head are three little ocelli, 

 surrounded l)y stiff hair, and tbei'<> is a fringe of stiff hair along the hind mar- 

 gin of the bead. The thorax is crossed in front of the middle by a transverse 

 impressed line, .-ind at the posterior margin the triangular scutellum is sepa- 

 rated off by another impressed line or suture. On each side of the middle is a 

 concave, smooth, longitudinal impressed line or channel extending the full 

 length of the thorax, and a little darker in color; nearer to each side is a.nother 

 such impress(>d line, also a little darker in color, giving the impression of four 

 longitudinal darker lines on a deep gray ground. There is also cm each side of 

 the middle a Idack, crescent-shaped spot; the impressed lines are not set with 

 liair, but there is a row of stiff hair at each side of the lines, and the surface is 

 elsewhere rather densely clothed with still' hair. The abd(mien is small in pro- 

 portion to the thorax, and is almost as liroad as it is long, and flattened above. 

 It is somewhat jialer in color, and has a dusky median shade without distinct 

 boundaries. The upper side is (piite densely set with long, black, spinous hair. 



The legs are moderately long, blackish, the kneejoints marked with reddish, 

 the whole quite densely set with stiff blackish hair. 



There is very little difference in iU)pearance between the sexes, save that the 

 abdomen of the female is more obese than in the male.

1. Consideration of yields and maturity. — The value of the annual 

 tomato crop in New Jei-sey is computed to be over $1,000,000. At 

 least 15,000 acres are cultivated to su]:)ply the 75 canneries in the 

 State, and 2.000 for the general market. In view of the nuiguitude 

 of the industry and the imi)ortance of understanding the etl'ect of 

 fertilizers upon the yield and time of ripening, a Held experiment 

 was made to study the etfect of nitrate of soda upon early maturity 

 and yield. It included tests of the elfects of the nitrate Avhen used 

 in (litl'crent (piantities, in one api)lication and in two applications, 

 alone and with liberal amounts of phosphoric acid. Twelve plats 

 •were used, each one-twentieth of an acre in size. Nitrate was applied.
