AMERICAN FORESTRY 



they may be carried many miles away 

 before mating or laying their eggs. 

 However, even supposing this does hap- 

 pen, of the moths caught and killed 

 under any method only one-half are 

 females bearing eggs. Of this one-half, 

 it is easily seen that the majority have 

 already laid their eggs. Therefore, we 

 have expended a lot of money to kill a 

 few thousand moths, more than 75 per 

 cent of whom are perfectly 

 harmless, anyway, as they have 

 already done their damage and 

 would die a natural death in a 

 few days if not in a few hours, j 

 Does it pay ? I do not think so. ; 



"Now on the other hand, if 

 the trees which you wish to pre- 

 serve from them are thoroughly 

 sprayed any time within a 

 month or six weeks after the 

 eggs are laid, it stands to reason 

 that the young, tender larvse 

 who have got to feed for the 

 next two or three months will 

 easily succumb to the poison. 

 Here you have done a maxi- 

 mum of damage at a minimum 

 of cost, which, it seems to us, 

 is the ideal way of handling this 

 pest." 



Mr. Colton makes the fol- 

 lowing recommendations : 



Spraying during the summer 

 all roadside and street trees, 

 and also : 



To do more spraying in the 

 spring for gypsy moths ; 



To continue cleaning up or- 

 chard properties ; 



To clean up many of our 

 back roads, removing superfluous trees 

 and shrubs and those most likely to at- 

 tract the moths ; 



To obtain mounted specimens of 

 gypsy, brown-tail moths, and their 

 parasites for educational purposes ; 



To put in an educational exhibition 

 at the next Agricultural Fair and main- 

 tain the information bureau at the City 

 Hall office. 



Members of the Commission empha- 

 size the importance of forestry work in 

 park development as well as in the care 

 of shade trees in the streets, as they 



not only make the city more attractive 

 but make for a healthy and more con- 

 tented citizenship. The commissioners 

 state : 



'Tn regard to trees and shrubs — we 

 have set out a good many at the various 

 parks and playgrounds, and it is the in- 

 tention to follow out the order adopted 

 to plant about 500 trees on our streets 

 and avenues the coming year. 



J'RODUCTS OKiTHE_NURSERY. 



"Our nursery has been and is an im- 

 portant addition to our department. We 

 have a large and flourishing lot of 

 young trees growing, and we shall be 

 able to supply trees for the city at about 

 one-third of the cost that we have been 

 obliged to pay for them from time to 

 time, as we have needed them in the 

 past. If we are to make our city streets 

 and avenues attractive and beautiful 

 this work must be continued from year 

 to year, and we hope that we shall, by 

 you, be enabled to do so.
