182 HEARINGS BEFORE COMMITTEE ON AGRICULTURE. 
remedy for this stomach worm was devised by Doctor Stiles of the 
Bureau of Animal Industry a few years ago and was published, but so 
far as I know was not put in application in any part of the West unless 
it be in the northwestern Texas district. The remedy for this worm is 
coal-tar creosote. 
The Cuarrman. That is being published in all of the agricultural 
papers now. In them all you can see the advertisements of the creosote 
cure for stomach worms. 
Mr. Covitiz. The people in Montana do not use it at all. 
Mr. Scorr. Has your investigation gone far enough to determine if 
there is any poison in the loco weeds? 
Mr. Covitxis. It has not. We are continuing these investigations, 
having thrown out but one of these diseases, which has been mistaken 
for what probably is a loco-weed disease. We believe there is such a 
disease, and we shall proceed on that basis until we have either dis- 
covered —. 
The Cuarrman. The symptoms of loco poisoning in a horse is very 
much like staggers, and if this arises from the stomach worm it would 
give the same symptoms. 
Mr. Covitxte. This is in sheep. 
The Cuarrman. But not in horses? 
Mr. Covitiz. We have not found it in horses yet. 
Mr. Brooxs. Are there some in cattle? 
on CovitLE. Our investigation this year was made entirely with 
sheep. 
Mr. Brooks. A case in Colorado some time ago came under my 
notice where a whole range of cattle became infected with what they 
thought was loco poisoning, and on investigation their stomachs bore 
this feature which you speak of. 
Mr. Covitte. I believe we will still discover a loco disease, and we 
will be able to show these various other diseases which have been mis- 
taken for it. 
I want to call your attention to the adulteration of Kentucky blue- 
grass seed with Canada blue-grass seed. I told you last year, I believe, 
the causes of the low percentages of germination of Kentucky blue 
grass. Here is a sample that is absolutely worthless, although look- 
ing as though it were a very good sample [exhibiting sample]. We 
found it was killed by being heated in the windrows in which the seed 
was piled when gathered. This year we are taking up another phase 
of the Kentucky blue-grass inquiry—the adulteration of it with Cana- 
dian blue grass. I have here two samples, one bottle of Kentucky 
blue grass and one of Canadian blue grass, the Canadian blue grass 
being in most parts of the country a worthless grass. Here is a mix- 
ture of half Canadian blue grass, which to the ordinary eye and to the 
eye of all the seedsmen of Kentucky is ‘indistinguishable from pure 
Kentucky blue grass. 
The waty the seed has been distinguished is by plunging their hands 
into a sack, and if their hand is pricked they conclude it is Canadian 
blue grass, the reason of this-being that Canadian blue grass as it comes 
upon the market invariably has in it the ends of the spine of the Can- 
ada thistle, while our own Kentucky blue grass is free from that. We 
are, however, able by the examination of these seeds to figure out the 
exact percentage of Kentucky blue grass and Canadian. There has 
been exported into the United States from Canada since 1902 over
