This child of my invention was nearly six feet square, exclusive of two triangular flaps to serve as a pillow by night and as the top and bottom of the sack by day. I call it "the sack," but it was never a sack by more than courtesy: only a sort of long roll or sausage, green waterproof cart-cloth without and blue sheep's fur within. It was commodious as a valise, warm and dry for a bed. There was luxurious turning room for one; and at a pinch the thing might serve for two. I could bury myself in it up to the neck; for my head I trusted to a fur cap, with a hood to fold down over my ears, and a band to pass under my nose like a respirator; and in case of heavy rain I proposed to make myself a little tent, or tentlet, with my waterproof coat, three stones, and a bent branch. It will readily be conceived that I could not carry this huge package on my own, merely human, shoulders. It remained to choose a beast of burden. Now, a horse is a fine lady among animals--flighty, timid, delicate in eating, of tender health; he is too valuable and too restive to be left alone, so that you are chained to your brute as to a fellow galley-slave; a dangerous road puts him out of his wits; in short, he's an uncertain and exacting ally, and adds thirty-fold to the troubles of the voyager. What I required was something cheap and small and hardy, and of a stolid and peaceful temper; and all these requisites pointed to a donkey. There dwelt an old man in Monastier, of rather unsound intellect according to some, much followed by street-boys, and known to fame as Father Adam. Father Adam had a cart, and to draw the cart a diminutive she-ass, not much bigger than a dog, the colour of a mouse, with a kindly eye and a determined under-jaw. There was something neat and high-bred, a quakerish elegance, about the rogue that hit my fancy on the spot. Our first interview was in Monastier market-place. To prove her good temper, one child after another was set upon her back to ride, and one after another went head over heels into the air; until a want of confidence began to reign in youthful bosoms, and the experiment was discontinued from a dearth of subjects. I was already backed by a deputation of my friends; but as if this were not enough, all the buyers and sellers came round and helped me in the bargain; and the ass and I and Father Adam were the centre of a hubbub for near half an hour. At length she passed into my service for the consideration of sixty-five francs and a glass of brandy. The sack had already cost eighty francs and two glasses of beer; so that Modestine, as I instantly baptized her, was upon all accounts the cheaper article. Indeed, that was as it should be; for she was only an appurtenance of my mattress, or self-acting bedstead on four castors.
