The principal currency of Our School was slate-pencil. It had some inexplicable value, that was never ascertained, never reduced to a standard. To have a great hoard of it, was somehow to be rich. We used to bestow it in charity, and confer it as a precious boon upon our chosen friends. When the holidays were coming, contributions were solicited for certain boys whose relatives were in India, and who were appealed for under the generic name of "Holiday-stoppers"--appropriate marks of remembrance that should enliven and cheer them in their homeless state. Personally, we always contributed these tokens of sympathy in the form of slate-pencil, and always felt that it would be a comfort and a treasure to them. Our School was remarkable for white mice. Red-polls, linnets, and even canaries, were kept in desks, drawers, hat-boxes, and other strange refuges for birds; but white mice were the favorite stock. The boys trained the mice, much better than the masters trained the boys. We recall one white mouse, who lived in the cover of a Latin dictionary, who ran up ladders, drew Roman chariots, shouldered muskets, turned wheels, and even made a very creditable appearance on the stage as the Dog of Montargis. He might have achieved greater things, but for having the misfortune to mistake his way in a triumphal procession to the Capitol, when he fell into a deep inkstand, and was dyed black, and drowned. The mice were the occasion of some most ingenious engineering, in the construction of their houses and instruments of performance. The famous one belonged to a Company of proprietors, some of whom have since made Railroads, Engines, and Telegraphs; the chairman has erected mills and bridges in New Zealand.
