THE CANADIAN HORTICULTURIST 



attempting to make theirescape througli 

 the netting, numerous visiting bugs 

 were at the outside of the cover at- 

 tempting to make their way in. The 

 same result was noted as following the 

 application of corn-cobs dipped in solu- 

 ble phenyle, a liquid posessing a power- 

 ful oduur resembling that of coal tar. 



Paris green mixed with water, half a 

 teaspoonful to two gallons, when care- 

 fully applied to both sides of the leaves 

 of cucumber or melon vines, is nearly 

 efficacious ; when applied only to the 

 upper side of the leaves, however, it is 

 of less value, as the beetles remain mvich 

 of the time during sunny weather upon 

 the lower side of the leaves and upon 

 the stems. 



Kerosene emulsion, diluted witli 

 eight parts of water, did not keep away 

 the beetles, while it was injurious to the 

 foliage. 



The cabbage caterpillar, the larva of 

 Pier is rapae, was effectually mastered 

 by the use of Buhach powder applied 

 with a bellows. We are making further 

 trials to determine what degree of di- 

 lution may answer for successful use. 



The aspai'agus beetle, Cirocens as- 

 paragi, has made its appearance in the 

 iStation garden. We find Paris gieen 

 applied in water, sure death to the 

 larva% although neither this nor the 

 kerosene emulsion seems to have appar- 

 ent effect upon the beetles themselves. 



The currant worm, the larva of 

 Nematus netitricosus, succumbs readily 

 to hellebore j)Owder, when the applica- 

 tion is made while the dew is on the 

 ))lants so as to cause tlu; powder toadhere 

 to the leav(!s. A})plif'd so sis to adhere 

 the application lasts for several days ; 

 the tlust of th(^ hellebore kills, howev(;r, 

 vei-y rajiidly, tli(M;aterj)illars with whicli 

 it comes into contact, and the subst;ince 

 may be a]>j)lied dusted from a dredg<M', 

 as soon as the young larva; appear. The 

 kerosene eunilsion, as noted above, was 

 but partially successful. Buhach pow- 



der in the dilution of a quarter of a 

 pound to three gallons of water was 

 but ])ai-tially successful. 



Buhach is the trade name for the 

 pulverized flowers of Pyrethrum cine- 

 rariixfolium, now extensively cultivated 

 in (Jalifornia. It is sold, })ut up in tin 

 cans, and should lie })urchased in these 

 original jiackages. Its use as an insecti- 

 cide is highly recommended by our best 

 entomologists, and it is cei-tainly worthy 

 of extended trial. — E. Lewis Sturte-

THE OLEANDER. 



This beautiful shi-ub belongs to the 

 Dog-bane family, and is poisonous. It 

 is found in the Levant, and some parts 

 of Palestine. In Florida it is so 

 common as to be little esteemed. It 

 glows in hedges and groves, and often 

 attains a height of twenty -five and 

 thirty feet. Galveston is called the 

 Oleander City because it grows there so 

 abundantly. They are planted in rows 

 on the outer edge of the sidewalk, 

 and just inside of the fence of many 

 residences, so that they form a perfect 

 arch, and ai-e laden with bloom for 

 several months. The red is the most 

 common variety, and is the hardiest, 

 though the white is by no means rare. 

 Galveston, Texas, is situated on an 

 island of the same name. The soil is 

 sand, with a mixture of decayed 

 vegetabh; matter. 



In starting Oleanders, after they have 

 attained a height of eight or ten in(;hes, 

 it is best to pinch ort' the stalk above 

 th(! second or third joint, and this will 

 foi'ce it to branch ; after these shoots are 

 sutli<uently grown, pinch them back, 

 and thus a thick bushy i)lant will re- 

 sult, and blossoms lie nnu-h more abun- 

 dant. 



Here at the Noi-th we i'ai<'ly find other 

 than the red oi' i-ose coloi', but there 

 are numerous beautiful varieties ; of a
