It was all very well to make good resolutions, but quite another matter to keep them. The beach near Sandsend was an especially fascinating part of the coast. It abounded with little, shallow pools among the rocks, where such a variety of beautiful anemones, madrepores, sea-cucumbers, and other marine objects might be seen that it almost resembled an aquarium. None of these treasures were to be found at Birkwood, where the cliffs were of a different geological formation; indeed, these particular few miles of shore were a noted spot for zoologists, and could show more choice species than anywhere else within a radius of fifty miles. It was not astonishing, therefore, that the girls stopped to marvel at some of these flowers of the sea, to watch the anemones stretching out their delicate, brilliantly coloured tentacles, to admire the corallines or the many strange forms of zoophytes, to chase spider crabs, and to pick up rare shells, and gather some of the lovely seaweeds that fringed the pools. They quite forgot the time, and went dawdling on from one interesting rocky basin to another, wishing they had a glass jar, or a bucket, in which they could carry some specimens back to the Grange. "Don't you think we might put a few anemones in our handkerchiefs?" suggested Aldred. "Not an atom of use! They die directly they're out of water. We tried it once before, and it wasn't a success," replied Phœbe. "We'll tell Miss Drummond about the place, and ask her to bring us for an expedition some day," said Dora. "The school aquarium needs replenishing badly." They had been walking, or, rather, strolling for about an hour when they reached a small bay, which lay between two promontories. The water here was so low that they decided they might as well cross the sands, instead of keeping close under the cliffs; they made a bee-line, therefore, for the opposite headland, jumping over the narrow channels that intercepted their path. On the flat sandbank they found at least a dozen large jellyfish, left stranded by the tide. Aldred insisted upon picking up some of these and restoring them to their native element; and she kept poking about in so many heaps of seaweed, and investigating such a number of species, that the other girls began to despair of ever getting her back to Birkwood. "We shall be all in the dark if we don't mind!" remonstrated Phœbe. "We've been sauntering along as if we had the whole day before us." "And as if there were no tide! Just look behind you!" exclaimed Myfanwy.
