 rope from the top, when it is accessible. The rope should always 

 he tied under the arms of the person lowered, as substances, 

 detached from above by the friction of the rope, may, by fall- 

 ing on him, stun him for a moment, and cause him to lose his 

 hold. But in all places and at all times an egg-collector should 

 recollect that identification and authentication are his main 

 objects, to attain wliicli no trouble is too laborious, no care too 

 great.
