40 BOARD OF AGRICULTURE. 



freely. Another thing in regard to a peach orchard is this r 

 We have found that when an orchard reaches its maturity 

 and begins to fail, then it is best to apply manure very freely 

 indeed, and, as Prof. Maynard says, either in the fall or 

 very early in the spring. 



Prof. Clark. The reason why I asked the question was 

 this, that I have seen trees where fertilizers had been ap- 

 plied that did not seem to improve under the treatment, but 

 when they were cut back severely then there was a strong 

 growth, with good, thrifty-looking leaves. I do not under- 

 take to contradict Mr. Augur and say there was no disease 

 there ; but still the trees made a good, strong, thrifty growth 

 and were brouo;ht back to a condition of some value. 



Mr. Augur. I think there is no way of rejuvenating a 

 tree more thoroughly than by cutting back and getting a 

 new growth. 



Prof. Clark. In regard to the quince, I found this year 

 that the flat-headed borer was doing more damage than I 

 expected. In looking for this insect, you need to look only 

 on the south or southwest side of the tree. Where you 

 see a spot which perhaps looks a little moist, as if the dew 

 had stayed there longer than it ordinarily would, if you dig 

 there you will be likely to find a very small flat-headed 

 borer, and it is sure death to the tree if you do not get it 

 out. In regard to applying manure to an orchard in the 

 fall, I think it makes a difference where that orchard is. If 

 it is on a hillside I should say, wait until spring ; if on level 

 land, where it does not wash, apply it in the fall. 



Mr. Augur. A single word more in regard to paris 

 green. I do not apprehend the least danger from its use if 

 it is mixed in the right proportions. If you get paris green 

 that is strictly pure and in good condition, use a teaspoon- 

 ful to a pail of water, and make three applications with a 

 hand-pump to the tree, one early and two later, I think you 

 will secure perfect innnunity from the codling moth, the 

 canker worm, and even from the apple maggot. 



Mr. Bkiggs. In regard to the black knot on the plum, 

 I have tried for the three last years linseed oil. I take a 

 paint brush and daub over those knots, and I find they stop 

 growing and the tree keeps on as usual. I have tried it on
