SHEARING. " When the sheep 

 are to be shorn, they are driven to a 

 pen or other enclosed space, and 

 brought one by one to the shearers. 

 Tlie slieep to be shorn is first placed 

 upon his rump, and the shearer, with 

 the shears, beginning at the neck, 

 clips in a circular direction down the 

 l)elly towards the back. The animal 

 is then laid on his side, and kept 

 down by the leg of the shearer, who 

 clips the fleece all round to the back. 

 Turning the animal on the other side, 

 he clips, in like manner, round to the 

 back; then raising the sheep, he clips 

 the part of the fleece not yet cut 

 away, and so lets the animal go, ta- 

 king care that it shall not entangle 

 itself with the fleece. The fleece, as 

 soon as it is shorn, is taken away by 

 an attendant, spread out, neatly roll- 

 ed up with the inner surface outmost, 

 and then deposited in some dry place 

 until it is packed in the wool sheets."

 mowing of weeds in rivers and ponds

 tied or riveted togetlier, and worked 

 by means of ropes like a saw from 

 one shore to the other, called shear- 

 ing ; but the first mode is generally 

 reckoned the best, and is unquestion- 

 ably so in agriculture."'
