1906.] ESSENTIALS IN FUTURE SHEEP BREEDING. 61 



Now comes another thing. We are not always sure. 

 These worms will live, or the eggs will live, we do not know 

 which, over winter, and infect the pasture. Keep in mind the 

 fact that an old sheep is most likely to be always more or less 

 infected with them. To be safe then, under the circumstances, 

 wherever it can be done, it is better not to pasture the same 

 field two years in succession. Many a man, however, is not 

 fixed so that he can do that. He has got to use his pasture 

 every year. If he is going to keep sheep he wants to keep 

 them on it. If such a man will provide simply a covered box 

 of salt, the box being covered so that the rains will not wash 

 away the salt, but so that the sheep can get their noses into it, 

 and with four quarts of salt mix a gill of turpentine, it will 

 have a good -effect. I remember when I was a boy that my 

 father on Saturdays when I was not attending school would 

 say to me sometimes, " Bub, I guess we better go to the woods. 

 You are at home, and I guess we better go and get some pine 

 saplings. The sheep need something green." You do not do 

 that. Now we should notice this fact, that a sheep would be 

 his own doctor if he could. We had some of these worms back 

 in those days, but by just such treatment as that our fathers 

 really kept them under subjection. My father' and your father 

 thought sheep needed something green to gnaw at, and there- 

 fore furnished them with that kind of material. Now we know 

 why they went for them. It practically kept them clean of 

 the worms. You accomplish practically the same purpose 

 with the salt and turpentine. When you mix the turpentine 

 with salt and put it in an infected pasture the result is sure 

 to be good. I have been surprised when carrying on experi- 

 ments with a flock of sheep that I knew had worms to see 

 how readily they would lick up my box of salt with the turpen- 

 tine in it, and to see how much more salt they would eat when 

 the turpentine was in it than when it was not. Therefore, if 

 you will provide the flock with that box of salt, it is one of the 

 best things you can do. When that is done we can pasture 

 year in and year out, in my judgment, so far as these worms 

 'are concerned. While this treatment will not kill the long 

 worm it will so saturate the system with turpentine that when 

 the little fellows hatch out they will not live long. 



Now there is another thing. It is an unseen foe. Every 

 sheep today needs looking over. The sheep of today need
