the first time before the leaf buds open. Put in the arsenic witli 

 the Bordeaux mixture for this spraying. The Bordeaux will 

 ward off the fungus, and the poison will kill the insects, especially 

 the early hatched tent caterpillars. The next spraying is made 

 just after the blossoms have fallen, when the little apples are in 

 an upright position, and their calix standing up. The last spraying 

 is done Avhen the little apples are of the size of hickory nuts. 



To Mr. Mann. — How many times do you spray? 



Answer. — I spray first, just before the buds open, then again 

 soon after the blossoms fall, repeating the operation every four or 

 five sprayings, using the Bordeaux mixture. I also use a pound of 

 Paris green in 54 gallons of the Bordeaux, for every spraying, 

 even the one before the buds open. I have never burned any 

 foliage with that formula, except on peach trees. I know it is not 

 the standard formula, but I have found it the best. I used it to 

 kill the forest worm, and killed the whole mass with one spraying. 



Question. — When shall we spray to kill the codling moth ? 



Mr. Smith. — Just after the blossoms have fallen and the calix 

 end of the young apple is standing upward. The poison falls 

 into the calix or blossom end, and, when the worm begins to eat. 

 its way into the apple, it is killed by the poison. Paris green, 

 green arsenoid and white arsenic are used. White arsenic is mixed 

 with common washing soda, and remains in suspension much bet- 

 ter than does Paris green, and costs much less, while it is fully as 

 effective. 



Question. — Is there a law to prevent spraying fruit trees while 

 in blossom? 



Mr. Rice read the text of such a law, and said it was enaete I 

 at the solicitation of the bee-keepers, it having been proved that 

 the spraying of trees while in bloom, not only poisoned the bees 

 who were in the blossom in search of honey, but that they had 

 actually carried the poison on their wings, to the hive, thereby 

 poisoning the whole colony. He would not, in any case, spray 

 trees with poison during the blossoming period, because it neither 

 prevents the attacks of the fungus nor kills the insects, while it 

 has been proved that it very seriously injures the fruit. 



Question. — Wliat is the cause of beans not coming in leaf after 

 coming up ? What is the'remedy ? 



Mr. Woodward. — It is what is known as " anthracnose," a little 

 canker spot that comes out on the stalk and eats off the bean leaf 

 before it has an opportunity to grow. The remedy is sprayi 2 

 with the Bordeaux mixture, early, as soon as the beans begin to 

 appear.
