Something wrong with the tank - Jack's wisdom and Peterkin's impertinence - Wonderful behaviour of a crab - Good wishes for those who dwell far from the sea - Jack commences to build a little boat.
REST is sweet as well for the body as for the mind.During my long experience, amid the vicissitudes of a chequered life, I have found that periods of profound rest at certain intervals, in addition to the ordinary hours of repose, are necessary to the wellbeing of man.And the nature as well as the period of this rest varies, according to the different temperaments of individuals, and the peculiar circumstances in which they may chance to be placed.To those who work with their minds, bodily labour is rest.To those who labour with the body, deep sleep is rest.To the downcast, the weary, and the sorrowful, joy and peace are rest.Nay, further, Ithink that to the gay, the frivolous, the reckless, when sated with pleasures that cannot last, even sorrow proves to be rest of a kind, although, perchance, it were better that I should call it relief than rest.There is, indeed, but one class of men to whom rest is denied.There is no rest to the wicked.At this I do but hint, however, as I treat not of that rest which is spiritual, but, more particularly, of that which applies to the mind and to the body.
Of this rest we stood much in need on our return home, and we found it exceedingly sweet, when we indulged in it, after completing the journey just related.It had not, indeed, been a very long journey, nevertheless we had pursued it so diligently that our frames were not a little prostrated.Our minds were also very much exhausted in consequence of the many surprises, frequent alarms, and much profound thought, to which they had been subjected; so that when we lay down on the night of our return under the shelter of the bower, we fell immediately into very deep repose.I can state this with much certainty, for Jack afterwards admitted the fact, and Peterkin, although he stoutly denied it, I heard snoring loudly at least two minutes after lying down.In this condition we remained all night and the whole of the following day without awaking once, or so much as moving our positions.When we did awake it was near sunset, and we were all in such a state of lassitude that we merely rose to swallow a mouthful of food.As Peterkin remarked, in the midst of a yawn, we took breakfast at tea-time, and then went to bed again, where we lay till the following forenoon.
After this we arose very greatly refreshed, but much alarmed lest we had lost count of a day.I say we were much alarmed on this head, for we had carefully kept count of the days since we were cast upon our island, in order that we might remember the Sabbath-day, which day we had hitherto with one accord kept as a day of rest, and refrained from all work whatsoever.However, on considering the subject, we all three entertained the same opinion as to how long we had slept, and so our minds were put at ease.
We now hastened to our Water Garden to enjoy a bathe, and to see how did the animals which I had placed in the tank.We found the garden more charming, pelucid, and inviting than ever, and Jack and I plunged into its depth, and gambolled among its radiant coral groves; while Peterkin wallowed at the surface, and tried occasionally to kick us as we passed below.Having dressed, I then hastened to the tank; but what was my surprise and grief to find nearly all the animals dead, and the water in a putrid condition!
I was greatly distressed at this, and wondered what could be the cause of it.
"Why, you precious humbug," said Peterkin, coming up to me, "how could you expect it to be otherwise? When fishes are accustomed to live in the Pacific Ocean, how can you expect them to exist in a hole like that?""Indeed, Peterkin," I replied, "there seems to be truth in what you say.Nevertheless, now I think of it, there must be some error in your reasoning; for, if I put in but a few very small animals, they will bear the same proportion to this pond that the millions of fish bear to the ocean.""I say, Jack," cried Peterkin, waving his hand, "come here, like a good fellow.Ralph is actually talking philosophy.Do come to our assistance, for he's out o' sight beyond me already!""What's the matter?" inquired Jack, coming up, while he endeavoured to scrub his long hair dry with a towel of cocoa-nut cloth.
I repeated my thoughts to Jack, who, I was happy to find, quite agreed with me."Your best plan," he said, "will be to put very few animals at first into your tank, and add more as you find it will bear them.And look here," he added, pointing to the sides of the tank, which, for the space of two inches above the water-level, were incrusted with salt, "you must carry your philosophy a little farther, Ralph.That water has evaporated so much that it is too salt for anything to live in.You will require to add FRESH water now and then, in order to keep it at the same degree of saltness as the sea.""Very true, Jack, that never struck me before," said I.
