Mr. N. H. Oowdry also writes of its depredations on the fruit of apples and 

 pears at Waterford, Ont. The same complaint came from I£r. J. A. Link, of Sombra, 

 Ontario. 



Remedy. — The only remedy is early spraying, while the caterpillars are small and 

 while they are feeding on the buds and young foliage. Luckily for the fruit grower 

 these caterpillars are always accompanied when in large numbers by parasitic enemies. 



The Rose Beetle (Macrodactylue subspinosus, Fab.), Fig. 50. — This well-known 

 enemy of the fruit grower, which every year does so much harm by eating the flowers 

 of grapes, apples, pears, roses, plums, raspberries, blackberries, and in fact all plants 

 belonging to the Rose family, as well as many other kinds of trees, did some harm 

 this year in the hotter western sections of the Province. It occurred in 

 large numbers near Niagara upon the young fruit of apples, in some cases 

 actually covering the fruit. There is only one brood of this pest, the mature 

 beetles last for about five weeks. There is perhaps no fruit iDsect known 

 more difficult to combat than this is. The ordinary insecticides have little 

 effect on it. Covering rose bushes with netting and beating the beetles from 

 Kig. 50. £ ne b us b. es into pans containing coal oil can be practised on a small scale. 

 The only remedy which so far has been found at all effective on a large scale " is to 

 spray grape vines and fruit trees with a wash made by adding three or four pecks of 

 freshly slaked lime and a quart of crude carbolic acid to 50 gallons of water." Dr . 

 C. M. Weed.) 



The Raspberry Sawfly {Monophadnus rubi, Harris), was more than usually 

 abundant in the western counties of the Province, but where promptly sprayed with 

 Paris green and water, and later when the fruit was forming with white hellebore, 

 was easily disposed of. 



Scale insects. — The advent of the San Jose' Scale in Ontario had a remarkable 

 awakening effect on the fruit growers of the province, and, as a consequence, there has 

 been during the past season far more enquiry with regard to injurious insects than has 

 ever been the case in a single year before. The vigorous policy of the provincial Gov- 

 ernment and the excellent conscientious work done by the Inspector, Mr. George E. 

 Fisher, and his assistants, backed up by a rigorous application by the Federal Govern- 

 ment of the San Jose Scale Act has undoubtedly had a good effect not only among the 

 thinking fruit growers of the Dominion, but upon statesmen in other countries who have 

 made several enquiries as to what steps were being taken in Canada to stamp out this 

 most injurious insect and prevent further importations from infested countries. Having 

 had ample opportunity of examining the districts which were infested, I can bear testi- 

 mony to the great success which has attended these efforts. The investigations in con- 

 nection with the San Jose Scale have brought to light other scale insects where their 

 presence was not suspected ; both the Forbes Scale and the Putnam Scale have been 

 found to be widely distributed, but in very few instances have they occurred in injurious 

 numbers. These two scales are of particular interest owing to their very close superfi- 

 cial resemblance to the San Jose Scale ; the microscopic difference of structure, however, 

 can at once be discovered when the scale insects are taken from their scales and after 

 proper preparation examined under the miscroscope. In addition, both of these species 

 lay eggs at certain times of the year, while the San Jose Scale, it is alleged, never does 

 so. The Forbes Scale (Aspidiotus Forbesi, Jnsn.) and the Putnam Scale, (A. ancylus, 

 Put.) can be successfully combated by spraying the trees with whale-oil soap, one pound 

 in two gallons of water. The best time to make the application is early in spring before 

 the trees are covered with foliage. 



The Scurfy Bark-louse {Chionaspis furfurus, Fitch.), Fig. .51., wide-spread, but not 

 very abundant nor injurious has been found in many localities in the western part of the 

 province, and, like the the very injurious Oyster-shell Bark-louse, can be destroyed with
