Habits, etc. — As the habits of this clumsiest, most stupid, ungainly and un- 

 touchable of rodents are known to so few people, I will outline them briefly. 

 They are nowhere " in their element." In water they can just manage to 

 paddle and scull along, being too fat to sink. On land they crawl like a huge 

 tortoise both in pac6 and gait. When pursued on land they seek preferably 

 the nearest hole that will at least cover the head, wedging themselves tightly 

 therein, leaving the huge bristling back and the ponderous tail for the enemy 

 to fool t^fith. Sometimes they take to a tree, ascending to the summit, but 

 they are slow climbers. The tail is used as a flail to parry attack. The 

 quills are not detached except by contact, anchoring themselves by the finely 

 barbed points, and thus become detached from their loose hold on the por- 

 cupine's skin. They work their way into skin and muscles quickly and auto- 

 matically, and are found in all parts of the anatomy of wild animals which 

 sometimes eat porcupines when driven by hunger. Porcupines are said to be 

 atboi-eal. They do ascend ahd descend trees to get bark and twigs for food. 

 In doing so they again display their innate awkwardness, the huge tail lurch- 

 ing ftom side to side as they shin slowly up, threatening at every step to throw 

 the animal to the ground, but their strength is enornftous, and sheer might of
