When the two lads returned with the sledge, it was time to rest for the night; but with early dawn we were again busily at work. The sledge was loaded with the new boat, and everything else we could pack into it, and we turned our steps homeward, finding the greatest difficulty, however, in getting our vehicle through the woods. We crossed the bamboo swamp, where I cut a fine mast for my boat, and came at length to a small opening or defile in the ridge of rocks, where a little torrent rushed from its source down into the larger stream beyond; here we determined to make a halt, in order to erect a great earth wall across the narrow gorge, which, being thickly planted with prickly pear, Indian fig, and every thorny bush we could find, would in time form an effectual barrier against the intrusion of wild beasts, the cliffs being, to the best of our belief, in every other part inaccessible. For our own convenience we retained a small winding-path through this barrier, concealing and defending it with piles of branches and thorns, and also we contrived a light drawbridge over the stream, so that we rendered the pass altogether a very strong position, should we ever have to act on the defensive. This work occupied two days, and continuing on our way, we were glad to rest at Falconhurst before arriving (quite tired and worn out) at Tentholm. It took some time to recruit our strength after this long and fatiguing expedition, and then we vigorously resumed the task of finishing the canoe. The arrangements, I flattered myself, were carried out in a manner quite worthy of a ship builder; a mast, sails, and paddles were fitted, but my final touch, although I prized it highly and considered it a grand and original idea, would no doubt have excited only ridicule and contempt had it been seen by a naval man. My contrivance was this: I had a couple of large air-tight bags made of the skins of the dog-fish, well tarred and pitched, inflated, and made fast on each side of the boat, just above the level of the water. These floats, however much she might be loaded, would effectually prevent either the sinking or capsizing of my craft. I may as well relate in this place what I omitted at the time of its occurrence. During the rainy season our cow presented us with a bull-calf, and that there might never be any difficulty in managing him, I at a very early age pierced his nose and placed a short stick in it, to be exchanged for a ring when he was old enough. The question now came to be, who should be his master, and to what should we train him? "Why not teach him," said Fritz, "to fight the wild animals, and defend us, like the fighting bulls of the Hottentots? That would be really useful!" "I am sure I should much prefer a gentle bull to a fighting one!" exclaimed his mother; "but do you mean to say tame oxen can be taught to act rationally on the defensive?"
