species and apparently we have got a lead on control. Mr. Casper thinks there is no reason why he shouldn't start in the first brood, although he has had about four years build up of the thing and no wonder it is bad. If we should try that another year, I would say we should start about the middle of June, because when he looked on the 27th of June the show was about over.

MEMBER: Your lattitude is about the same as Evansville?

MR. CHANDLER: Yes, Carbondale is almost on the due west line with Henderson, Kentucky, and Anna is 20 miles south of Carbondale.

MEMBER: One hundred miles north would be about two weeks later.

MR. CHANDLER: Yes, I wouldn't be surprised if it wouldn't be later. We thought maybe you might have to spray when the adults were out. We didn't know whether any material would go through that spittle. We thought you might have to spray and envelop the tree when the adults were around.

MEMBER: I saw some spittle bugs in Northern Michigan on wild hazel, and I am wondering if they are a pest on filberts.

MEMBER: We have no damage on filberts and I think we have spittle bugs in St. Louis. Our first brood comes between the first of June and the tenth, and in the last eight years they have been very serious.

MEMBER: Did you say Northern Peninsula of Michigan?

MEMBER: We have reports from Illinois and Missouri and Mr. Armstrong found it over at Princeton, Kentucky, and I know it is in Indiana.

MR. McDANIEL: I have seen some on pecans in Tennessee, but not as abundant as in Union County.

MEMBER: English walnuts in Ohio.

H. F. STOKE: I am in southwestern Virginia. I can say that we have spittle bug in the South. I am not sure it is the same species. When I get it determined, I will let you know.

DR. CHASE: That occurs in all the southern states. It is quite bad in Georgia and Florida and Alabama and in fact all the southern states.

MR. McKAY: It is very bad on weeds and grass in our orchards.

MR. CHANDLER: That's another species.

MR. McKAY: I have never seen any on our nut trees.

MEMBER: Just before this attack on the nut trees it was real bad on clover and grasses in our area.

MEMBER: That comes a little earlier. We ought to be sure that we get that determined. Dr. Milton W. Sanderson has had to send some specimens to a specialist in this group in Lawrence, Kansas.[1]

MEMBER: Are there just two broods?

MR. CHANDLER: There might possibly be three. I have another cage in my check block in which I collected the live ones, and I am going to find out whether they produce or don't.

MEMBER: There are two broods in Iowa.

MEMBER: Do I understand the common spittle bug is an enemy to nut trees?

MEMBER: That is for young nursery seedlings.

MR. CHANDLER: Did you see these big trees where I told you about having the crop? I explained for several minutes that there must be two varieties.

MR. FERGUSON: There is a spittle bug that bothers the June berries.

DR. ROHRBACHER: We have a spittle bug we had a year or two in Iowa on the elm trees.

At this time Dr. Colby would like to make a few announcements.

DR. COLBY: I just had a call from Tubby Magill. He is over in Danville and he has burned out a bearing and he is going to get over here for this afternoon. We will have to pinch-hit the rest of the morning.

DR. ROHRBACHER: We will now have a presentation by Dr McKay on the Preliminary Results of the Training of Chinese Chestnut Trees.
