to enforce this ruling.
Undoubtedly sooner or later there will be a test case to determine
whether or not the state has this authority.

I listened this afternoon to a discussion about walnut trees shading the
highway. I have no practical experience to know whether these trees do
any damage to crops on account of the shade, but supposing you raised a
fine walnut tree along the highway and the tree begins to bear. Would
not the products you get from that tree more than offset the damage it
does to a crop close to the tree? I once had an aunt, when I was a very
small boy, and it seems to me she said that she raised forty bushels of
black walnuts on one tree. I saw that big hickory tree today. They
claimed they raised fifteen bushels on that tree. I thought forty
bushels was a lot to come off of one tree.

MR. BIXBY: That was in the husk. There have been records of
that kind in the husk.

SENATOR PENNEY: This bill has been introduced and passed and
Mr. Linton, who is practically the author of this bill, is desirous of
having this followed up in the different states. I think it would be a
good plan. What better investment could you make to beautify our
highways than the planting of good trees? In the southern part of the
state of Michigan there are quite a lot of good trees, black walnuts,
butternuts, which not only add beauty to your highways but are useful in
many ways. During the war we know that the government scoured the whole
country to find walnut trees to make stocks for guns, and to use in
airplanes for propeller blades. They used the shucks to make gas masks.
The trees could be made of further service to man by planting them as
memorial trees. And again they furnish food, not only bear leaves but
food.

I would like to hear a discussion upon this bill from those who are from
other states. I would like to hear what their opinion might be as to the
different provisions of this bill.

PRESIDENT LINTON: The subject is now open for discussion. I am
sure that there are those here who would perhaps offer amendments to
that bill. They might desire to modify it some. They might desire to add
other features to it. For instance, it might be well to recognize the
desire at the present time to save useful bird life throughout the
country. That might be stated in the title to this bill as one of the
purposes of roadside planting. Certainly that would be one of the
results of road side planting.

SENATOR PENNEY: The bil
