TOBACCO FOR THOUSAND-LEGGED WORMS. 



A writer in the Weekly Florists' Review of April 9, 1903, Mr. Wil- 

 liam Scott, states, in answer to a correspondent of that publication 

 who requested a remedy for thousand-legged worms or millipedes 

 working on his ferns and which he stated were eating some of his 

 asparagus seed, that thousands of these creatures appeared on the sur- 

 face of rose beds, but that after putting bunches of tobacco stems on 

 the surface to keep down "green fly" or aphides, it was noticed that 

 the " thousand legs" lay around dead, and their demise could be 

 attributed to nothing but the tobacco. Mr. Scott therefore advises 

 that in order to rid greenhouses of "* thousand legs" to put plenty of 

 fresh tobacco stems among the pots. 



LIGHTS AGAINST THE IMPORTED CABBAGE WEBWORM. 



Mr. H. M. Simons, who appears to be the first person who has had 

 experience with Hellula undalis in this country, wrote from Charles- 

 ton, S. C.j August 11, 1902, that he captures many of the moths with 

 the aid of a barrel having all but four of the staves sawed out, leaving 

 4 inches from the bottom to form a tub in which to hold water. From 

 the top of this a light is suspended which attracts the moths. The 

 light barrels, as he terms them, were placed on plant seed beds of 

 cabbage. 



A thin scum of kerosene was used in this experiment, but it is sug- 

 gested that this be eliminated, in order not to destro} 7 predaceous 

 insects, such as ground beetles, which are almost sure to be attracted; 

 this suggestion being made in view of the fact that the destruction of 

 one individual of a beneficial species is equivalent to the destruction 

 of perhaps 20 to 100 injurious ones. The useful insects can be easily 

 picked from the water, and though they may apparently be dead, they 

 usually recover and crawl away. 



HAIR WORMS IN CABBAGE. 



Many complaints have been made during the present year of what 

 have been termed by various persons as "snakes," "cabbage snakes," 

 "snake worms," and the like, and the subject has attained consider- 

 able newspaper notoriety. So many inquiries have been made as to 

 the identity of the creatures and their alleged poisonous qualities that 

 it has been thought well to give a short account of them, more particu- 

 larly as many persons fully believe the insects to be poisonous. This 

 is, of course, absurd, as the worms are not known to possess any toxic 

 properties whatever, but it is certain that, although they are not injuri- 

 ous to the cabbages their presence is not desirable, as they really injure 

 cabbage for sale. The specimens received during the year, with a few 

 exceptions, have been found in heads of cabbage. We have ascertained
