This section of the book is from the "Stories of Animal Sagacity" book, by William Henry Giles Kingston.
Mice, I suspect, are fully as sagacious as rats; perhaps they are more so. In their foraging expeditions what cleverness do they exhibit! When one or two have been caught in a trap, how careful are the rest of the community not to be tempted by the treacherous bait.
A honey-pot had been left in a closet, from the wall of which some of the loose plaster had fallen down. In the morning, the honey being wanted, the pot was found with a considerable portion abstracted. Outside of it was a heap of mortar reaching to the edge, forming an inclined plane, while inside a similar structure had been raised with the loose plaster. From the marks on the shelf, it was clearly the work of a mouse; which had thus, by means of a well-designed structure, obtained entrance and exit.
If a little mouse, to gain its object, which you deem a wrong one, can employ so much intelligence, how much more should you exert your superior faculties to attain a right object.
