The tenants of the poultry-yard swarmed, and they lived on the surplus, but it became necessary to reduce the population to a more moderate number. The pigs had already produced young, and it may be understood that their care for these animals absorbed a great part of Neb and Pencroft’s time. The onagers, who had two pretty colts, were most often mounted by Gideon Spilett and Herbert, who had become an excellent rider under the reporter’s instruction, and they also harnessed them to the cart either for carrying wood and coal to Granite House, or different mineral productions required by the engineer. Several expeditions were made about this time into the depths of the Far West Forests. The explorers could venture there without having anything to fear from the heat, for the sun’s rays scarcely penetrated through the thick foliage spreading above their heads. They thus visited all the left bank of the Mercy, along which ran the road from the corral to the mouth of Falls River. But in these excursions the settlers took care to be well armed, for they met with savage wild boars, with which they often had a tussle. They also, during this season, made fierce war against the jaguars. Gideon Spilett had vowed a special hatred against them, and his pupil Herbert seconded him well. Armed as they were, they no longer feared to meet one of those beasts. Herbert’s courage was superb, and the reporter’s sang-froid astonishing. Already twenty magnificent skins ornamented the dining-room of Granite House, and if this continued, the jaguar race would soon be extinct in the island, the object aimed at by the hunters. The engineer sometimes took part in the expeditions made to the unknown parts of the island, which he surveyed with great attention. It was for other traces than those of animals that he searched the thickets of the vast forest, but nothing suspicious ever appeared. Neither Top nor Jup, who accompanied him, ever betrayed by their behavior that there was anything strange there, and yet more than once again the dog barked at the mouth of the well, which the engineer had before explored without result. At this time Gideon Spilett, aided by Herbert, took several views of the most picturesque parts of the island, by means of the photographic apparatus found in the cases, and of which they had not as yet made any use. This apparatus, provided with a powerful object-glass, was very complete. Substances necessary for the photographic reproduction, collodion for preparing the glass plate, nitrate of silver to render it sensitive, hyposulfate of soda to fix the prints obtained, chloride of ammonium in which to soak the paper destined to give the positive proof, acetate of soda and chloride of gold in which to immerse the paper, nothing was wanting. Even the papers were there, all prepared, and before laying in the printing-frame upon the negatives, it was sufficient to soak them for a few minutes in the solution of nitrate of silver.
