northern United States lambs born the first of February, for example, may- 

 be kept with their mothers in a clean field or pasture until the last of 

 March, as in the case of those born at the beginning of winter, but unlike 

 the latter they will not then be old enough to wean. Accordingly they are 

 not separated from the rest of the flock, but the ewes and lambs are moved 

 together to a second clean pasture April 1st. May 1st they are moved to a 

 third clean pasture. May 15th they are moved again, and finally the lambs 

 are weaned June 1st at the age of four months, and moved by themselves to 

 a clean pasture. In the case of lambs born the first of March and weaned 

 the first of July three additional clean pastures would be required for use 

 during the month of June, and with later lambs a still greater number of 

 pastures would be necessary. 



TREATMENT FOR STOMACH WORMS. 



Among the remedies which may be used to remove stomach worms may 

 be mentioned coal-tar, creosote, bluestone and gasoline. 



The animals to be treated should be deprived of feed for twelve to six- 

 teen or even twenty-four hours before they are dosed, and in case blue- 

 stone is used should receive no water on the day they are dosed, either 

 before or after dosing. In drenching, a long-necked bottle or a drenching 

 tube may be used. In case a bottle is used the dose to be given may be 

 first measured off, poured into the bottle, and the point marked on the 

 outside of the bottle with a file, so that subsequent doses may be measured 

 in the bottle itself. A simple form of drenching tube consists of a piece of 

 rubber tubing about 3 feet long and one-half inch in diameter, with an 

 ordinary tin funnel inserted in one end and a piece of brass or iron tubing 

 4 to 6 inches long and of suitable diameter inserted in the other end. In 

 use the metal tube is placed in the animal's mouth between the back teeth 

 and the dose is poured into the funnel, which is either held by an assistant 

 or fastened to a post. The flow of liquid through the tube is controlled 

 by pinching the rubber tubing near the point of union with the metal tube. 

 It is important not to raise the animal's head too high on account of the 

 danger of the dose entering the lungs. The nose should not be raised 

 higher than the level of the eyes. The animal may be dosed either stand- 

 ing on all fours or set upon its haunches. It has been found by experi- 

 ment that if the dose is taken quietly most of it will pass directly to the 

 fourth stomach when the animal is dosed in a standing position, and that 

 when the animal is placed on its haunches only a part of the dose passes 

 immediately to the fourth stomach. From this it is evident that the posi- 

 tion on all fours is preferable, as more of the dose passes to the place 

 where its action is required. 



Great care should be used not only in dosing to avoid the entrance of 

 the liquid into the lungs, but also in the preparation and administration of 

 the remedy so that the solution may not be too strong or the dose too large. 



COAL-TAR CREOSOTE. 



Good results have been obtained from a single dose of a 1 per cent 

 solution of coal-tar creosote. This solution is made by shaking together 

 1 ounce of coal-tar creosote and 99 ounces (6 pints 3 ounces) of water.
