There was yet another pet—one which had been very sluggish all through the winter, but now in fine sunshiny days fairly active, and ready upon this occasion to come forth and be fed.

Dexter rose very slowly, talking gently the while to the mice, which he coaxed to his hand with a piece of cheese, and then placed them upon the floor, while he went to a corner where, turned upside down upon a slate, stood one of Dan’l’s large flower-pots, the hole being covered with a piece of perforated zinc.

The pot was lifted, slate and all, turned over, and the slate lifted off, to display quite a nest of damp moss, which, as the boy watched, seemed for a few minutes uninhabited, but all at once it began to heave in one part; there was an increasing movement, as if something was gliding through it, and then from among the soft moss a smooth glistening head with two bright eyes appeared, and a curious little tongue darted out through an opening between the tightly-closed jaws.

There was no doubt of the nature of the creature, which glided forth more and more till it developed itself into a snake of a bright olive green, about thirty inches long, its singular markings and mottlings looking as bright as if it had been varnished.

Dexter watched the curious horizontal undulating movement of the little serpent for some time before he touched it, and then taking it up very gently, its tail hung swinging to and fro, while the front portion curved and undulated, and searched about for a place to rest till it found one upon the boy’s arm, up which it began to glide as if the warmth were pleasant, ending by nestling its head in the hollow of the elbow-joint.

Meanwhile there was another rustling and movement of the moss, but nothing showed for a time.

Dexter smoothed and stroked the snake, which seemed to be perfectly content when it was moved, but soon after began to insinuate its blunt rounded head here and there, as if in search of something, till its owner bore it to a large pickle-jar standing upon a beam nearly level with the floor, and upon his placing the reptile’s head on a level with the mouth, it glided in at once, inch by inch, over the side, and through Dexter’s hands, till it disappeared, the finely-graduated tail passing over the edge, and it was gone, the jar being its larder, in which were stored, ready for consumption, half a dozen of Dan’l’s greatest enemies—the slugs.

As Dexter turned to the heap of moss once more, at which one of the rabbits was sniffing, there was another heaving movement, followed by a sharp rap on the boards, the alarm signal of the rabbit which bounded away, while a blunt, broad head and two glistening eyes slowly appeared; then what looked like a short sturdy arm with outstretched fingers pressed down the moss, then another arm began to work, and by slow degrees a huge toad, which seemed to be as broad as it was long, extricated itself from the soft vegetable fibre, and crept away on to the boards, all in the most deliberate manner, as if it was too fat to move fast.

“Hallo, Sam!” said Dexter, laughing. “Why, you’ve been asleep for a month.”

The toad seemed to be looking up at him in an unblinking fashion, but did not move, and Dexter stooped down to touch it, but the moment his hand approached, the reptile rose on its legs, arched its back, lowered its head, swelled itself up, and uttered a low, hissing sound.
