result will be that the produce of the 

 cream of that meal is 112, or one 

 pint twelve one hundredths. Care 

 must be taken to lill these tubes as 

 soon as the pail is taken from under 

 the cow, for if any delay takes place 

 some of the cream will have ascend- 

 ed towards the top. The milk should 

 be taken from the middle of the 

 pail, which is to be done by dipping a j 

 cream-pot below the froth." — {Jouni.

 furnished at the top with two pieces 

 of wood projecting 10 inches, to hin- 

 der it from injuring the trees in pru- 

 ning, nailing, &c. An arrangement 

 of three ladders on a frame, capable 

 of being wheeled along, and in which 

 two of the ladders may be hoisted 

 one above the other, so as to reach 

 to the top of trees, is called an orchard 

 ladder.

 the genus Coccinclla. Most of the

LAMB. For the farmer, late lambs 

 dropped at grass time are best, as the 

 ewe yields more milk ; the teat of the 

 ewe should be cleared of any tags 

 that hinder suckling ; if she does not 

 own her lamb, put them together in a 

 pen and place a little salt on the lamb ; 

 if she licks it, a good feeling will soon 

 spring up. They are weaned at six 

 to eight weeks ; the rams are gelded 

 at one to three weeks old. By kill- 

 ing lambs at six months, the wool 

 becomes much more valuable. The 

 young ewes should not be put to ram 

 until two years.

LAMELLICORNS. A division of

 terior part of the head is commonly 

 dilated, and projects ; the mentum is 

 large, covering the labrum or incor- 

 porated with it, and bearing the pal- 

 pi. They are very numerous, feed on 

 excrements, rotten wood, and roots. 

 LAMENESS. "In the horse it 

 is brought on from various causes, 

 sprains, over-exertion, diseases of 

 the foot, &c. The muscles of the 

 shoulder are occasionally sprained, 

 and, in this case, the animal cannot 

 lift his foot without great difficulty ; 

 indeed, he will be observed to drag 

 his toe along the ground. In this 

 case few local measures can be adopt- 

 ed. The horse should be bled from 

 I the vein on the inside of the arm, fo-
