Conclusion. 



It will be seen by the above that in the first series the addition of the 

 skimmed milk rendered the paint more permanent while in series No. 2 

 it had the opposite effect. From the present appearance of the trees 

 painted we feel confident that No.'s 1, 2, 3, and 4 of the 2d series will 

 adhere sufficiently long to hold the Paris green during the winter and 

 that there can be but little, if any, danger from their use. 



NEW VARIETIES OF APPLES AND OTHER FRUITS. 



In every locality there are found growing local varieties of fruits of 

 more or less merit, which are known only to those sections, and as 

 most of our best varieties in cultivation are chance seedlings, we feel 

 hopeful that among the great number there may be many of value. 



For this reason we would urge every one who may have such varieties 

 of promise, to make careful observations as to their qualities. One of 

 the great advantages of such varieties is that they are mature trees or 

 plants and their merits are more or less known. There is need of im- 

 proved varieties of all of our fruits, yet no variety should be introduced 

 unless it has decidedly superior qualities to those already in cultivation. 



In order to aid in this matter, we would ask all growers who have 

 any varieties of fruit of merit to send a sample to the Horticultural De- 

 partment of the College Experiment Station for comparison and test. 

 Named varieties of which the owner may have lost the name will be 

 received and named if possible. 



SULPHUR AS AN INSECTICIDE AND FUNGICIDE. 



The fumes of sulphur are well known to be destructive to both plant 

 and animal life, but in its crystalHne or " brimstone " form it is wholly 

 insoluble and therefore inactive as an agent of destruction to either 

 plants or animals. 



Almost every season the report comes to us through the agricultural 

 journals or from other sources, of experiments made with the insoluble 

 form of sulphur for the prevention of insect injuries to the foliage of 

 fruit or other trees. 



The most common method of apphcation is to insert the sulphur 

 in holes bored in the trunks of the trees, with the idea that it will be 

 dissolved by the sap of the tree and carried to the foliage or fruit in 

 such quantities as to render it offensive to insects. No longer ago than 

 the past spring it was reported that the Forester of the city of Boston 

 had bored large holes in many of the large elms within the city limits, 

 and had inserted sulphur to prevent the elm beetle from injuring the 

 foliage.
