No. 4.] FRUIT GROWING. 177 



Mr. Edsox. I am acquainted with cranberry growers on 

 the Cape who have not been very successful with Paris 

 green, but tobacco is a very sure remedy. I use about forty 

 barrels on five acres. 



Professor Ferxald. I think the gentleman would be 

 quite astonished if he could see the replies to the circular 

 letters I sent out, and see what the different men say. No 

 two agree on anything. 



Mr. .Edsox. They go back to tobacco after they have 

 been experimenting with other things, and say that it is a 

 sure remedy if it is put on at the right time. As the pro- 

 fessor says, go out early in the spring, and you will find that 

 the insects have drawn two cranberry leaves together and 

 are feeding there ; when they eat through the leaves the 

 tobacco will kill them every time. But when you apply it 

 when they are encased between two leaves, it does not reach 

 them. If you can catch them just at the right time, the 

 tobacco is a sure remedy. 



Professor Ferxald. There is this that I should say in 

 regard to the use of Paris green on any plant. It is desirable 

 to mix it with something to make it adhere to the foliage, and 

 probably nothing is better than glucose. Use a couple of 

 quarts of glucose or a quart even to a barrel of water ; then 

 the Paris green will adhere much better, and it will not be 

 so likely to run off or to be washed off by light rains. 

 That I should say would be very desirable in the use of Paris 

 green anywhere. 



Mr. Edsox. I have been experimenting somewhat this 

 year in using potash in connection with tobacco. I put about 

 a pound of potash to fifty gallons of water, and it seems to 

 work very well. 



Professor Ferxald. I have not finished my experiments 

 on the cranberry insects, and what I say to-day will only 

 last, perhaps, a few hours. I may change my mind later. 



The Chairmax. The question this afternoon is the grow- 

 ing of fruit, as well as its enemies. Now, it is well known 

 that we have thousands of acres of land in Massachusetts 

 running up to wild, scrubby growth, that is admirably 

 adapted to the growth of the apple. It is not the valleys 

 and low lands most desirable for farm purposes that are most
