of the stone had been, lay crouched, as if asleep, one of the most beautifully-coloured frogs I had ever beheld. Its body was slender compared with most frogs, and its skin covered with stripes of bright reddish-brown and grayish-green, in such a manner as to recall the beautiful markings of the tiger's hide; and, since the time alluded to, it has received the name of _Tigrina_ from Leconte, its first scientific describer. How long I should have been content to gaze at these beautiful animals, as they lay basking in the living water, I know not, had not the intense heat made me feel the necessity of seeking a shade. It was now past twelve o'clock: I began to retrace my steps towards the city; and, without any particular object, moved along by the little galleries examined in the morning. I had advanced but a short distance, when I found the last place where I had broken open the gallery was _repaired_. The earth was perfectly fresh, and I had lost the chance of discovering the miner, while watching my new acquaintances in the stream. Hurrying onward, the same circumstance uniformly presented; the injuries were all efficiently repaired, and had evidently been very recently completed. Here was one point gained: it was ascertained that these galleries were still inhabited, and I hoped soon to become acquainted with the inmates. But at this time it appeared fruitless to delay longer, and I returned home, filled with anticipations of pleasure from the success of my future researches. These I shall relate on another occasion, if such narrations as the present be thought of sufficient interest to justify their presentation to the reader. JOHN. No. II.
