50 HEARINGS BEFORE COMMITTEE ON AGRICULTURE. 
Mr. Satmon. It is about the same disease. 
The Cuarrman. It is a parasite. : 
Mr. Satmon. It is a parasite which belongs to the same species, but 
it is not transferred from cattle to sheep. It is a different variety, 
but it produces the same sort of disease in cattle. It pulls them down 
so in their flesh that in the western country when bad weather comes 
on in the winter they lose a great many. ; ; 
The Cuarrman. When did this cattle scab make its appearance! [ 
never heard of it until this year. 
Mr. Satmon. It made laappenenes in northern Dakota. That is 
the first I heard of it. 
The CHarrman. When‘ 
Mr. Satmon. Three or four years ago. 
The Cuarrman. As long ago as that? 
Mr. Satmon. That was the first time they had any outbreak there 
that has been at all serious. une 
Mr. Scorr. Where is it supposed to come from’ Where is it gen- 
erated from in the first place? 
Mr. Satmon. I do not know where it is generated in the first ee 
but it came in from Canada, probably. Where they got it 1 do not 
know. 
The Cratrman. I suppose Canada says it came in from the United 
States. 
Mr. Satmon. Very likely. It is a more virulent form of cattle 
mange or cattle scab than we have ever had in this country before. It 
seems to spread more rapidly and affect cattle more seriously than any 
other. Really, in some of the States out there it is an extremely seri- 
ous matter. They say in North Dakota that if we shut in the diseased 
cattle they will not be able to market any another year, and we must 
go up there and cooperate with them in some way in the treatment of 
these cattle in order to get them out to market. .. 
Mr. Bowrr. Is this mange you speak of something like the dog 
mange? 
Mr. Satmon. It is something of the same nature, and while when it 
first starts it does not seem to be very serious, it progresses until it 
almost ruins the cattle. 
The CuarrMan. Can you dip them in winter / 
Mr. Salmon. We can not dip them in that country in winter. It is 
too cold up there; but we will probably introduce toward spring a 
treatment of spraying or brushing material over them so as to treat 
those that are not very severely affected, and then later we will have 
to dip the ones where the disease has spread. 
The Crarrman. Does it occur all over the body. 
__ Mr. Saumon. It starts along the back and in the root of the tail, and 
it spreads; and after they have had it awhile it goes all over the body. 
The Cuarrman. It starts generally in the root of the tail? 
Mr. Satmon. In the root of the tail or along the spine. 
a ue Is the disease fatal? 
r. SaLmon. It is not usually fatal of itself, but it th 
oo ma teats = OD time the loss is very feitich seni ca 
en really a badly infected animal is not fit f 
bad and they are in bad health. . ieee? ines 
The Caarrman. Naturally they would carry no flesh.
