Birds’ eggs as a collection had hitherto been represented in the Museum by one addled swan’s egg, but now they took rank among the objects of existence. Here my father dictated the conditions under which they might be acquired, namely, that no egg was to be taken from any nest unless that nest contained four, and under no circumstances was more than one to be taken. There was of course no questioning his decision, but it seemed a pity to leave the great tit in the gorse bush to bring up a family of fifteen after our levy had been made, and never to be able to get a wood-pigeon’s egg at all, since those prudent birds refused to lay more than two. But here Charles the groom shone forth gilded with the glory of celestial charity, for he came to me one morning with his entire collection of eggs and “would I accept of them?” Was there ever such a groom? And among these was a pair of wood-pigeon’s eggs, so those parsimonious parents were thwarted. For a while games were quite in abeyance, romantic natural history held the field. For consider: my sister Maggie and I had heard that otters were found in Cornwall, and on that simple fact we built up the following fairy-like adventure. There was a round copse, rather lonely, on the edge of our fields; from it the ground declined in a steep down to the bottom of a valley, through which ran a stream so small that by wetting only one foot you could get across it at its widest part. But it ran below bushes and under steep banks, and it seemed highly probable that some of these Cornish otters lived there. Well, otters went about on land as well as in the water, and the lure of imagination pictured them taking a nice walk up this down and coming to the lonely copse. This grew very thick in brushwood, through which the otters (now indigenous in the copse) would certainly walk. So we hung nooses of string here and there a foot or so from the ground so that the otter might, in his walks, insert his head in the noose which would then be pulled tight, and we should come and capture him. This gave rise to further considerations; he might struggle, and get hurt if not strangled in the noose, so we must clearly be on the spot to loosen the noose, and substitute for it a chain and collar of one of the dogs. But if the otter saw us, he would probably gallop back over the down to his stream, so we built a hut woven of withies between two trees in which we could lie _perdus_, and watch for the otter. Then we should lead him chained to the stables, and gradually tame him till he could come out walking with us in company with Watch and the nanny-goat which already formed part of the family procession. (A second goat, called Capricorn, was presently added, but he had an odious habit of standing upright on his hind legs and hurling himself like a battering-ram against the hinder-parts of the unobservant, and when harnessed to a small truck which was used for gardening purposes, galloped with it at such speed
