the canal which was to close the plateau on the west, from the south angle of Lake Grant to the angle of the Mercy. There was there two or three feet of vegetable earth, and below that granite. It was therefore necessary to manufacture some more nitro-glycerine, and the nitro-glycerine did its accustomed work. In less than a fortnight a ditch, twelve feet wide and six deep, was dug out in the hard ground of the plateau. A new trench was made by the same means in the rocky border of the lake, forming a small stream, to which they gave the name of Creek Glycerine, and which was thus an affluent of the Mercy. As the engineer had predicted, the level of the lake was lowered, though very slightly. To complete the enclosure the bed of the stream on the beach was considerably enlarged, and the sand supported by means of stakes.
By the end of the first fortnight of December these works were finished, and Prospect Heights—that is to say, a sort of irregular pentagon, having a perimeter of nearly four miles, surrounded by a liquid belt—was completely protected from depredators of every description.
During the month of December, the heat was very great. In spite of it, however, the settlers continued their work, as they were anxious to possess a poultry-yard.
It is useless to say that since the enclosing of the plateau had been completed, Master Jup had been set at liberty. He did not leave his masters, and evinced no wish to escape. He was a gentle animal, though very powerful and wonderfully active. He was easily taught to make himself useful by drawing loads of wood and carting away the stones extracted from the bed of Creek Glycerine.
The poultry-yard occupied an area of two hundred square yards, on the southeastern bank of the lake. It was surrounded by a palisade, and in it were constructed various shelters for the birds which were to populate it. These were simply built of branches and divided into compartments, made ready for the expected guests.
The first were the two tinamous, which were not long in having a number of young ones; they had for companions half a dozen ducks, accustomed to the borders of the lake. Some belonged to the Chinese species, of which the wings open like a fan, and which by the brilliancy of their plumage rival the golden pheasants. A’ few days afterwards,
