THE PORCUPINE. Tuis is one of the most curious of quad- rupeds. When full grown, it measures two feet in length. Its general color is a grizzled, dusky black. The upper part of its head and neck is furnished with Jong light-colored hairs, capable of being raised or depressed at pleasure. Most parts of the back and sides are armed with spires, which are longest on the centre of the back. When the animal is excited, these spires, which are its wea- pons of defence, are raised. The Porcu- pine generally sleeps through the day, and only leaves its burrow in the evening, (98)
