and at different places, and one never knows the strength his so- 

 lution is going to be from time to time. 



Prof. Forbes — I think the spraying should cease about a month 

 before gathering the fruit, though the boys who sprayed our trees 

 this year ate the fallen apples all through the spraying season and 

 no bad results came from it. I have doubted some whether spray- 

 ing the peach could be made a success, for the reason the curculio 

 sometimes comes at more than one period of the season. It seems 

 that some fail to transform in the fall, and remain in the ground 

 in the pupa state over winter, complete their growth in the spring 

 and emerge from the ground at a later season than those that trans- 

 formed at the usual season. 



Mr. Orr — What time of day did Mr. Goodrich spray? 



Mr. Goodrich — I preferred in the morning after the dew was 

 off. 



Mr. Orr — Did not the little drops of water which formed on the 

 foliage from the spraying machine cause little lenzes through 

 which the sun shone and burned the foliage? 



Mr. Goodrich — That might be the case sometimes, under some 

 circumstances, but I think the Paris Green did the injury in my 



case.

Mr. Coe asked Prof. Forbes if he had tried spraying flowers, 

 such as dahlias, etc., with Paris Green? 



Prof. Forbes — No I have not. Hellebore is used in such cases. 

 Paris Green should be avoided where children are liable to come 

 in contact with it. 



ORCHARD AND CULTURE. 



BY J. V. COTTA, NURSERY. 



Mr. President and Members of the Northern Illinois Horticul- 

 tural Society : 

 The growing of an apple orchard would seem to be such a 

 simple matter that any person of ordinary intelligence might be 

 expected to make a fair success of it, and if a new beginner, or 

 even a person of some experience in this line, should wish to be 

 particularly well informed, he would not only have access to 

 the works of Warder, Downing, Thomas and other competent 

 writers, the reports of our Horticultural Societies, but also the
