My feelings were as mixed as a crushed nut sundae. So the Professor hadn't gone to Brooklyn after all! What did he mean by prowling after me like a sleuth? Was it just homesickness for Parnassus? Not likely! And then the horrible noises I had heard in the night; had some tramp been hanging about the van in the hope of robbing me? Had the tramp attacked Mifflin? Or had Mifflin attacked the tramp? Who had got the better of it? I picked up the muddy cap and threw it into the van. Anyway, I had problems of my own to tackle, and those of the Professor could wait. Peg whinneyed when she saw me. I examined her foot. Seeing it by daylight the trouble was not hard to diagnose. A long, jagged piece of slate was wedged in the frog of the foot. I easily wrenched it out, heated some water, and gave the hoof another sponging. It would be all right when shod once more. But where was the shoe? I gave the horse some oats, cooked an egg and a cup of coffee for myself at the little kerosene stove, and broke up a dog biscuit for Bock. I marvelled once more at the completeness of Parnassus' furnishings. Bock helped me to scour the pan. He sniffed eagerly at the cap when I showed it to him, and wagged his tail. It seemed to me that the only thing I could do was to leave Parnassus and the animals where they were and retrace my steps as far as the Pratt farm. Undoubtedly Mr. Pratt would be glad to sell me a horse-shoe and send his hired man to do the job for me. I could not drive Peg as she was, with a sore foot and without a shoe. I judged Parnassus would be quite safe: the lane seemed to be a lonely one leading to a deserted quarry. I tied Bock to the steps to act as a guard, took my purse and the Professor's cap with me, locked the door of the van, and set off along the back track. Bock whined and tugged violently when he saw me disappearing, but I could see no other course. The lane rejoined the main road about half a mile back. I must have been asleep or I could never have made the mistake of turning off. I don't see why Peg should have made the turn, unless her foot hurt and she judged the side track would be a good place to rest. She must have been well used to stopping overnight in the open.
