Timber Growing. 167 



a street tree. It is also frequently partially or entirely stripped 

 of its foliage in midsummer by certain caterpillars which may be 

 often seen gathered in rather uninviting masses on the body of 

 the trees, going through the moulting process. The drip of the 

 tree is apt to disfigure the fences and vegetation or ground under 

 it. It is apt to shed its foliage freely, and is Dot a real cleanly, 

 nice, inviting tree for shade or ornament. It grows rapidly, and 

 its timber qualities are excellent; but I do not think we can 

 recommend it generally as a street tree in the city or village. In 

 the country, where there are three or four rods of unoccupied 

 land along the road, it may be well to plant it. 



Mr. Ames — It is said that orchard trees standing near the 

 Black Walnut do not bear. 



Mr. Ford — It might be well to find out if this is a fact. I 

 know that fruit trees standing near the trees I have spoken of 

 bear abundantly. 



Mr. Stickney — If it has this effect at all, I should attribute it 

 to its being a gross feeder. 



President Smith — In father's orchard, in New Jersey, Black 

 Walnut trees stood among the apple trees, and I saw no differ- 

 ence in their bearing on this account. 



Dr. P. R. Hoy — The main reason why vegetation does not 

 thrive under these trees is the poisonous character of the drip. 

 The juice of the leaf is poisonous, and a decoction made of it and 

 applied to a horse with a sponge will keep off flies, and i3 offen- 

 sive to almost all insects. 



Mr. Plumb — In relation to prolonging the life of our native 

 forest trees, I would say that some time ago I saw a Maple or- 

 chard of old trees, as old as any in the country, standing in the 

 cleared land in the northern part of Waupaca county. It was 

 owned by a German farmer. On clearing off the timber around, 

 he had cut away about one-third of the tops of the maple trees 

 he wanted to save, and he continued to cut away a portion of the 

 tops for a number of years. In this way he had saved the trees. 

 I have no doubt the same treatment would work favorably with 

 other forest trees. 



A short time since I was in De Pere, and the manager of the
