According to the Mexicans, there are two kinds of rabies: that affecting the head and that affecting the stomach. When animals have _rabia_ in the head they become stupid and move about slowly, biting at everything they see or touch. They are not violent, and become very thin. But when they have rabies in the stomach it gives them great pain, and they bark and howl and race about frantically, chasing other animals and tearing them. Mr. Cipriano Fisher, of Santa Catarina, told me of his experience with a coyote which had rabies in the stomach. He was hunting deer at Cape San Lucas, and had killed two. Carrying the smaller one and his gun to camp, he returned unarmed, except for the knife which every one wears in that region, to bring in the other. As he went down a deep cañon he heard a coyote ahead, howling in the peculiar way which he knew to be characteristic of the _rabioso_. All the hunters claim they can recognize the howling of a rabid coyote, and they say that no other animal will answer it or go near it. The howling approached rapidly. Knowing that he could not escape by running back uphill, nor kill it with his knife without being bitten, he stepped quickly into the brush and cut a long green club. As he turned back into the open place he saw the coyote down the cañon, leaping up and snapping at the air. When the coyote saw him it broke into a furious run up the trail, and when, as he says, about thirty feet away, made a flying leap at his face. He jumped to one side, struck the rabid animal in the back of the head as it passed, and killed it with the one blow. Skunks are particularly dangerous to persons who sleep out at night. J. Ellis McLellan, a field collector of the United States Department of Agriculture, whom I met at San José del Cabo, told me of an unpleasant experience he had with a skunk while coming down from La Paz. On account of the heat he had ridden in the night as far as Agua Caliente, where he stopped near a ranch house to sleep till morning. Although the night was warm, he covered his head with a _serape_ for protection from insects and wandering animals. Early in the morning he was awakened by a twitching at his blanket and, raising the _serape_, saw a skunk biting and jerking at it. Realizing the gravity of the situation, he reached for his heavy knife, and then, suddenly throwing aside the _serape_, he leaned forward and put his whole force into one blow. As he ducked under the blanket again, for protection, the dogs from the house rushed out in a body and pounced upon the dying skunk, which they worried on top of McLellan until the ranch people beat them off. When skunks bite at men's toes and ears, or at blankets in this way, it is taken as an indication that they are rabid.
