NOTES AND COMMENTS. 



lington Bay and in the Niagara District last 

 year, and seem to be gaining ground year 

 by year, owing to neglect of proper reme- 

 dies. One of the most reliable preventive 

 measures is suggested -by a study of the in- 

 sect itself. The male moth is winged, bu^ 

 the female is not winged and therefore must 

 climb the trunks of the trees to deposit its 

 eggs. 



Therefore a tree protector of some kind 

 about the trunk will effectually prevent the 

 eggs from being deposited upon the tree 

 above it, or the worms from crawling up if 

 hatched out below. Bands of heavy paper 

 tightly fastened around the trunk and be- 

 smeared with some sticky substance, such 

 as coal tar or printer's ink, will serve the 

 same purpose. Some report using a mixture 

 of 3 pounds of resin 

 to 2 pounds of castor 

 oil, melted together 

 and applied directly 

 to the trunk of the 

 tree. The writer tried 

 sticky bands in his 

 own orchard some 

 years ago, and suc- 

 ceeded in completely 

 routing the worm, 

 hundreds of females 

 being caught fast trying to walk through a 

 sticky bandage of coal tar. There are two 

 species of Canker worms, Anisopterix ver- 

 nata (the spring canker worm) and A. pom- 

 etaria (the fall canker' worm) so that one 

 must be vigilant both in spring and fall, 

 and the bandages should be applied toward 

 the end of October, and kept sticky until 

 about the ist of May. 



The common remedy, spraying with Paris 

 green at the rate of one pound to 150 gal- 

 lons of water, is effective if applied while the 

 worms are very young, but, if delayed until

the worms are even half grown, it is not 

 very effective. A better remedy is the strong 

 solution of white arsenic known as the Ked- 

 zie mixture, which was given on page 184 

 (May No.). Prof Kedzie used 2 lbs. white 

 arsenic, 4 lbs. sal. soda and 2 gallons of 

 vater. This was boiled until the milky 

 color disappeared, showing that the arsenic 

 was dissolved. Then i pint of this was 

 added to 40 gallons of water. The addition 

 of 2 lbs. of lime to each barrel of this 

 mixture made the arsenic solution insoluble 

 and less apt to scald the foliage. 



The Georgian Bay Fruit Growers' Associa- 

 tion seems to be a most active and enter- 

 prising society. That they mean business 

 is evident from the work undertaken, which 

 may be classed under such heads as, co- 

 operative buying of baskets; pumps and 

 material for spraying; uniformity in methods 

 of cultivation, pruning and packing; co- 

 operative shipment and sale of fruit. At 

 Montreal a special forwarding agent for the 

 Georgian Bay packages of fruit is retained 

 during the shipping season, who will report 

 the condition the fruit arrives in Montreal, 

 the manner in which it is handled and placed 

 on shipboard. The secretary is Mr. Fred. 

 Marsh, whose ambition is to make the 

 Georgian Bay brand hold the top place in 

 the market. 



Spraying Demonstrations. — Actions speak 

 louder than words, even in horticulture, and 

 the man who can do a thing as well as tell 

 about the doing, is the man who is needed 

 these days. Secretary Creelman writes 

 that he has engaged Messrs. McNeill, 

 Carey and Lick for spraying demonstration 

 meetings to be conducted in connection with 

 the local fruit growers' associations in the 

 various parts of the province.
