"No, do not give them any: it appears to be cruel, but I want the intelligence of the poor animals to-morrow, and the want of water will make them very keen, and we shall turn it to good account. So now, William, we must not forget to return thanks to a merciful God, and to beg his care over us for this night. We little know what the day may bring forth. Good-night!" Chapter XVI William slept as sound as if he had been on shore in England upon a soft bed in a warm room - so did old Ready; and when they awoke the next morning it was broad daylight. The poor dogs were suffering for want of water, and it pained William to see them with their tongues out, panting and whining as they looked up to him. "Now, William," said Ready, "shall we take our breakfast before we start, or have a walk first?" "Ready, I cannot really drink a drop of water myself, and I am thirsty, unless you give a little to these poor dogs." "I pity the poor dumb creatures as much as you do, Master Willy; it is kindness to ourselves and them too, which makes me refuse it to them. However, if you like, we will take a walk first, and see if we can find any water. Let us first go to the little dell to the right, and if we do not succeed, we will try farther on where the water has run down during the rainy season." William was very glad to go, and away they went, followed by the dogs, Ready having taken up the spade, which he carried on his shoulder. They soon came to the dell, and the dogs put their noses to the ground, and snuffed about. Ready watched them; at last they lay down panting. "Let us go on," said Ready, thoughtfully; they went on to where the run of water appeared to have been - the dogs snuffed about more eagerly than before. "You see, William, these poor dogs are now so eager for water, that if there is any, they will find it out where we never could. I don't expect water above-ground, but there may be some below it. This beach is hardly far enough from the water's edge, or I should try in the sand for it." "In the sand - but would it not be salt?" replied William. "No, not if at a good distance from the sea-beach; for you see, William, the sand by degrees filters the sea-water fresh, and very often when the sand runs in a long way from the high-water mark, if you dig down, you will find good fresh water, at other times it is a little brackish, but still fit for use." "Look, Ready, at Romulus and Remus - how hard they are digging with their paws there in the hollow." "Thanks to Heaven that they are! You don't know how happy you have made me feel: for, to tell you the truth, I was beginning to be alarmed." "But why do they dig?" "Because there is water there, poor animals. Now you see the advantage of having kept them in pain for a few hours; it is in all probability the saving of all of us, for we must either have found water or quitted this island. Now let us help the poor dogs with the spade, and they shall soon be rewarded for their sufferings."
