HEARINGS BEFORE COMMITTEE ON AGRICULTURE. 55 
posed to know all about petroleum) told uy they could not dissolve 
sulphur in petroleum; but we have found since that this natural crude 
petroleum from Texas has a large quantity of sulphur already dis- 
solved in it, owing to some peculiar properties of the oil. 
Mr. Henry. A process you have not been able to discover? 
Mr. Satmon. A process we are not able to duplicate; but .it is 
already there, and it is very cheap. The oil can be bought for about 
3 cents a gallon. 
The Cuarrman. That kills the ticks, does it? 
Mr. Satmon. Yes; we experimented with it at our experiment sta- 
tion at Bethesda. 
The Cuarrman. Will one dipping kill them? 
Mr. Satmon. One dipping; yes, sir. Then late in the season we 
Semen) in Texas with it, and in both places it killed all the ticks 
and did not damage the cattle. 
The Cuarrman. How much did it cost to dip a steer? Have you 
any figures on that? 
Mr. Saumon. With that oil it did not cost very much. 
The Cuarrman. About how much? 
Mr. Satmon. It costs 3 cents a gallon, and about a gallon of oil is 
taken out of the dip with the steer. Then, it is necessary to count 
the interest on the plant, and so on, but if they are dipping a large 
number it will not amount to much. 
The Cuarrman. About 5 cents apiece 
Mr. Satmon. About 5 cents apiece. When we started in it was 
costing from 50 to 75 cents an animal, and they were very anxious to 
have them dipped at that price; but with this oil it will certainly be 
inside of 10 cents and possibly inside of 5. 
Mr. Scorr. You killed a good many animals in the beginning of 
these experiments, did you not? 
Mr. Satmon. Well, some, and some were damaged more or less. 
Mr. Scotr. And the owners suffered the loss? 
Mr. Satmon. Yes; they were willing to take the chances, you know. 
They were so anxious to get their cattle out. 
Mr. Lams. Have you-any bulletins on this, Doctor? 
Mr. Satmon. [ have not written up the dippings yet; no. 
Mr. Lams. When vou do [ wish you would send me some. 
Mr. Satmon. I will be very glad to do so. 
Mr. Wricut. In these various experiments do you send the inspect- 
ors wherever there is an infected flock? 
Mr. Satmon. Now we are sending inspectors to central shipping 
points to inspect the sheep that are to be shipped. 
Mr. Wricur. Seaboard and shipping points? 
Mr. Satmon. And in the interior also. For instance, in Wyoming 
we have certain places where our inspectors are stationed on the rail- 
roads. 
Mr. Wricur. Suppose a man had a large herd of dairy cows: you 
would not send an inspector to look them over? 
Mr. Satmon. No; we do not do anything with dairy cows. | 
Mr. Scorr. Doctor, with regard to this inspection in Wyoming that 
you have spoken of, is not that State doing anything along that line? 
Mr. Satmon. Yes, sir; they are cooperating with us. They have a 
sheep sanitary board, and they have made the regulations and helped 
to enforce them.
