spray pump, and since it kills only by contact, it is necessary to touch 

 each insect in order to kill it and hence the work must be done thorouerhlv. 

 It will not kill insects that may come along after the spraying is done as 

 will the arsenical spray. Aphis, or plant lice, are easily killed by this 

 spray, but are also killed by a spray of tobacco tea.^ Of course the spray- 

 ing should be done before they curl the leaves up. 



Paris green and lime may be added to this kerosene emulsion and 

 thereby combine the spray for both biting and sucking insects. This is 

 done by simply regarding the kerosene emulsion as so much water. 



When one is spraying with Bordeaux mixture for fungus diseases 

 the Paris green may also be added as though the Bordeaux mixture were 

 water, and again save the trouble of two sprayings. — Dr. J. M. Stedman,

HOW INSECTS SPEIs^D THE WINTEE.

Where are They? — Where are the insects which harassed the 

 farmer, fruit-grower, gardener or house-wife last summer? Doubtless 

 some of us would dismiss this question with the notion that the insects 

 are killed off by the rigors of winter, perhaps to be reincarnated, by 

 spontaneous generation or otherwise, in the spring. It is true that many 

 insects do succumb to zero weather, yet mother nature always sees to it 

 that even such insignificant (to many) creatures as the insects make 

 ample provisions for getting through the winter in some form, even 

 among "Greenland's icy mountains." Doubtless no kind or species 'tjf 

 insect was ever exterminated from the earth in historical times because 

 of inability to withstand winter weather. 



t 

 Erozen Insects. — One may ask. Can insects survive freezing? 



There are several records by careful observers of spiders, grubs and cater- 

 pillars being found frozen stiff in northern latitudes, so that they would 

 break like icicles; and yet when these were thawed out gradually they 

 would "come to life," as it were, and be all right. It is very essential 

 that there be a gradual thawing out, hence insects suffer greater mortality
