A few nights after this incident, the mother commenced in earnest to educate her young. Tenderly taking each in turn, she carried the nurslings into the water, and taught them, by a method and in language known only to themselves, how to dive and swim with the least possible exertion and disturbance.
Henceforward, throughout the summer, and till the foliage on the trees near the pool, chilled by the rapid fall of the temperature every evening, became thinner in the breath of the early autumn wind, the otter-cubs fished, and frolicked, and slept, or were suckled by their dam. Sometimes the whole family, together with the old dog-otter, adjourned to the middle of the meadow, and in the tall, dew-drenched grass skipped like kittens, though with comical clumsiness rather than with the agility they displayed in the water. Like kittens, too, the cubs played with their mother, in spite of wholesome chastisement when they nipped her muzzle rather more severely than even long-suffering patience could allow. The dam was at all times loath to correct her offspring, but the sire rarely endured the familiarity of the cubs for long. Directly they became unduly presumptuous he lumbered off to the river, as if he considered it much more becoming to fish than to join in the sport of his progeny. Perhaps, indeed, he deemed a change of surroundings essential that he might forget the liberties taken with him by his disrespectful youngsters.
When about three months old, Lutra began to show promise of that grace of form and motion which in later life was to be one of her chief distinctions. Her body, tail, and head gradually lengthened; and, as her movements in the water became more sinuous and easy, she tired less rapidly when fishing.
Autumn passed on towards winter, the nights were long, the great harvest of the leaves fell thickly on the meadow and the stream, the mountain springs were loosed in muddy torrents, and the river roared, swollen and turbid, past the "holt" under the trailing alder-twigs. The moorhens came back from the ponds where they had nested in April and May; the wild duck and the teal flew south from oversea, and in the night descended circling to the pool; a dabchick from the wild gorge down-river took up his abode in the sedges.
