might say that there are only throe points at which the infestation has extended to any 

 great proportions, that of Niagara, St. Catharines and in the southern part of the town- 

 ship of Harwich, in the County of Kent, in the neighborhood of Giles. Outside of these 

 there are a few other points where the infestation has spread to very narrow limits. In 

 addition to this, and what seems to me the most important part of our work was that we 

 were furnished with a list of the nursery stock which was supposed to be infested, in fact 

 some of it had been found to be infested, This nursery stock was followed through every 

 county in the province of Ontario without any exception, and last fall and this summer 

 about one hundred points have been liberated from infestation by the destruction of these 

 trees. We found the Scale in about one hundred places altogether and I was very much 

 struck by a remark which was made by a gentle man living in the County of Elgin with 

 whom a conple of Scale trees were found. He said to the young man who found the Scale 

 and who assisted him in destroying the trees : " Young man every such case of Scale that 

 you find, and destroy the trees, is worth to this country at least, $1,000." Figuring from 

 that standpoint, the value of these trees and the destruction of them is worth to this 

 country at least $100,000. We have not found Scale generally distributed outside the 

 points I have named, and a few others where it is not widely spread. 



Professor Lochhead spoke of the Scale as being in the neighborhood of Belleville, — 

 it was found on these young nursery trees down there at Belleville. It withstood 22 

 degrees below zero quite safely, and at the time, I thought that was miraculous and I 

 reported it to some of our entomologists and also to Dr. Howard of Washington who 

 seemed to think it was extraordinary, but lately I have read a remark in a Bulletin pub- 

 lished by Professor Newell, of Iowa, who said the scale would winter at St, Paul, Minn., 

 where eevoral times the mercury was 40 below zero, so that this Belleville matter does not 

 cut any figure, and we may look for Scale in any part of this country. I believe we may 

 look for Scale in any climate wherever trees will grow. 



In the Bay of Quinte district in the County of Prince Edward, we have been 

 examining and the examination is not quite completed, but we have not found Scale on 

 anything but these young trees. The Counties of Elgin, Kent and Essex are being 

 examined in the same way ; in Elgin no Scale has been found except on these young 

 trees, and in Kent we have found the Scale only in the township of Harwich and on the 

 Town-lines on either side bordering on the township of Harwich. Then there are several 

 points where these young trees were found and it was only at Kingsville where we foun I 

 the Scale at all. I have noticed this summer that where the trees were allowed to stand 

 and the Scale to accumulate the destruction was far-reaching and rapid. I have been 

 astonished at the distance the Scale will go. It spieads most rapidly in the direction of 

 the prevailing wind, and we can congratulate ourselves that in the district where it is 

 most extensive the prevailing winds will carry them out into the lake. I think that 

 insects carry the Scale a good deal, We have noticed in Niagara lately that owing to 

 the exceedingly dry weather that has prevailed there, the grass seems to have lost its 

 nourishment and the grasshoppers have taken to the trees for food. You can stand and 

 watch them. Sometin es their flight is only for a short distance from one tree to another, 

 at other times they will go away across the orchard. Frequently the; fly for a consider- 

 able distance. Of course the Scale goes with them wherever they go. I have an idea of 

 my own and I would like very much if some of these learned people would help me to 

 work it out. I have been trying my best to solve the matter for myself, and I find if we 

 put a mature male under the microscope and a little louse bsside him the mile i3 about six 

 times as large as the louse, and I have an idea that the male Scale is responsible for 

 distribution. They have broad strong wings and when they fly they go off with a bound, 

 it is no feeble flight. They can go right up in the air like a lark, and I think them quite 

 capable of carrying one or more of these mites with them ; however, I have never caught 

 them in the act, although I have spent a great deal of time trying to do so. I had a 

 splendid specimen the other day. It is difficult to get these males where you can watch 

 them, I found a splendid sample of Scale and I put it on a slide on the stove just a little 

 warm and the warmth of the fire started him out and I watched the male Scale slide 

 about on that piece of wood, and the way he figured on the stick was very instructive to
