effective strength of washes. As some washes are difficult for growers to 

 make, might I suggest to vendors of washes that they should be sold in 

 as concentrated a form as possible, obviating the necessity of paying 

 unnecessary rail carriage ? 



With regard to chemicals purchased for mixing one's own washes, 

 a guaranteed strength should be stated on invoices and insisted on by 

 purchasers, or trouble is likely to occur through variation of strength. 



Spraying Installations. — It would be interesting to know what is the 

 best system for a fair-sized plantation. At Glewstone Fruit Plantation, 

 owned by Mr. J. Martin Newton and myself, for an area of about 25 acres 

 our system is as follows : We have a small house near a stream with a 



h.p. Crossley oil engine and a 600-gallon tank sunk below the level 

 of the stream which can be thus rapidly filled. There is an iron under- 

 ground main pipe from this tank along the principal headland with taps 

 at intervals. To these taps we connect at right angles 15 feet lengths of 

 iron piping on the surface of the ground along a row of trees ; to this 

 iron pipe are fitted four 60 feet lengths of indiarubber hose, with spraying 

 arms and nozzles. This enables us to spray twelve rows of trees (say 500 

 trees) without shifting the iron pipes, so that we can easily spray 2,000 to 

 2,500 trees a day. The disadvantages are : — 



1. Amount of wash held in pipes. 



2. Wear on indiarubber hose through dragging on ground. 



3. Settlement of insoluble material in pipes. 



Can anyone suggest an improvement on this system ? 



I sincerely hope that our splendid Society — the Royal Horticultural 

 Society — will make experiments in fruit tree spraying, and will also have 

 at one of their shows a representative exhibition from all parts of spray- 

 ing machines and nozzles. 



Another suggestion I would make is that a representative body of 

 fruit growers should visit the United States and Canada, and study the 

 question of fruit tree spraying and kindred subjects, and give the British 

 fruit growers the benefit of their observations. 



My one hope and desire is that some practical results may spring from 

 this meeting. 



In conclusion I would say, " If you spray, spray regularly, spray 

 thoroughly, spray systematically, or don't spray at all ! " 



Discussion. 



Thj: Chairman : I have no doubt, after listening to the very interest- 

 in pajxTS which it has been our advantage to hear to-day, that it must 

 have given rise to a great deal of thought in the minds of all of us, and 

 perhaps to doubts in the minds of some. I confess that as far as my 

 layman's mind goes one doubt has been raised by a remark which 

 Mr. Massee interjected more than once in the course of his paper. I 

 have always been given to understand that if we did not preserve 

 foxes there would be no fox-hunting, and that if we did* not preserve 

 pheasants, there would be no pheasant-shooting. Mr. Massee seems to 

 have a sneaking affection in his heart for fungus ; for I noticed in the 

 course of his remarks that he pleaded for fungus— to give it a chance. It
