WHEN elder brothers insisted on their rights with undue harshness, or when the grown-up people descended from Olympus with a tiresome tale of broken furniture and torn clothes, the groundlings of the schoolroom went into retreat. In summer-time this was an easy matter; once fairly escaped into the garden, any climbable tree or shady shrub provided us with a hermitage. There was a hollow tree-stump full of exciting insects and pleasant earthy smells that never failed us, or, for wet days, the tool-shed, with its armoury of weapons with which, in imagination, we would repel the attacks of hostile forces. But in the game that was our childhood, the garden was out of bounds in winter-time, and we had to seek other lairs. Behind the schoolroom piano there was a three-cornered refuge that served very well for momentary sulks or sudden alarms. It was possible to lie in ambush there, at peace with our grievances, until life took a turn for the better and tempted us forth again into the active world. But when the hour was tragic and we felt the need for a hiding-place more remote, we took our troubles, not without a recurring thrill, to that enchanted place which our elders contemptuously called the “mouse-cupboard.” This was a low cupboard that ran the whole length of the big attic under the slope of the roof, and here the aggrieved spirit of childhood could find solitude and darkness in which to scheme deeds of revenge and actions of a wonderful magnanimity turn by turn. Luckily our shelter did not appeal to the utilitarian minds of the grown-up folk or to those members of the younger generation who were beginning to trouble about their clothes. You had to enter it on your hands and knees; it was dusty, and the mice obstinately disputed our possession. On the inner walls the plaster seemed to be oozing between the rough laths, and through little chinks and crannies in the tiles overhead our eyes could see the sky. But our imaginations soon altered these trivial blemishes. As a cave the mouse-cupboard had a very interesting history. As soon as the smugglers had left it, it passed successively through the hands of Aladdin, Robinson Crusoe, Ben Gunn, and Tom Sawyer, and gave satisfaction to them all, and it would no doubt have had many other tenants if some one had not discovered that it was like the cabin of a ship. From that hour its position in our world was assured.
