BEST VARIETIES OF TREES FOR STREET PLANTING. 109 
Mr. Harris: The sugar maple, as a street tree, is very short 
lived, but where it is grown in a grove it does perfectly. 
The President: I hada grove on my farm, and there was about 
an acre of sugar maples, and I never saw trees grow more perfectly 
than those did; there was not another tree in the grove. They were 
thick, close together like a thick clump of trees. 
Mr. Jewett: There is a certain kind of tree I have seen in the 
park at St. Paul. It is a beautiful tree, and I have been told it would 
take the place of the cottonwood, and that is the Carolina poplar. 
It is a beautiful tree and a rapid grower. I do not know why we 
have not got it, because the tree is perfectly hardy. 
Mr. Moyer: The Carolina poplar is the cottonwood. 
Mr. Jewett: They claim it isa distinct variety and it grows no 
cotton. 
Mr. Philips, (Wis.): Several of the nurserymen in our. state 
have been planting the Carolina poplar, and it is never taken for our 
cottonwood. They are a beautifully shaped tree, but they are differ- 
ent from the cottonwood. They are setting them at a good many 
different places. 
Mr. Underwood: There is a difference in cottonwoods. They un- 
doubtedly belong to the cottonwood family, but they are entirely distinct 
from the cottonwood of the Mississippi river. They are a very rapid 
grower, although our Mississippi river cottonwoods grow fast also. But 
there is a variety of the cottonwood known as the Carolina poplar, of 
which we have grown a good many young trees. I have never seen any 
large trees, but they are quite easily distinguishable from the ordinary 
cottonwood. 
In regard to the maple. We have passed through a very severe ex- 
perience with the hard maple and with the soft maple, as well. I think the 
maples demand different culture from that which they generally receive, es- 
pecially in street planting. I think all trees need to be planted with a view 
to furnishing moisture, and that is particularly true of the maple. The 
soft maple will die down in the top as badly as any tree we have and the 
hard maple will kill back if they do not have enough moisture. Hf you 
want to have a hard maple tree do well anywhere the body should be pro- 
tected from the sun by wrapping it, or let it kill down and come up again 
from the sprouts and grow up in a natural top. Besides that the roots 
must have plenty of moisture. They must be planted in such a way that 
all the water falling in the immediate vicinity shall be available for the 
trees, and then the ground should be kept loose on top so that the water 
can get in. Our hard maple grove came near perishing for lack of moist- 
ure, simply because we let the grass grow and cut it down and kept the 
ground very tidy. Now we leave the leaves on the ground and do not 
rake anything off, but keep conditions the same as exist in the woods, and 
_ J feel as though we were doing the right thing. 
Mr. Moyer: I think the hard maple is a difficult tree to grow on the 
prairie, but thirty miles from where Mr. Wheaton lives there is a fine grove 
of hard maple.
