'By this path, and by that,' said the old woman, pointing him, 'go on till you come to the thick waters of the Bitter Lake; they are blacker than night, and their weight is heavier than lead, and in the depths dwells the Camphor-Worm. Once a year, when the air is sweetest with the scents of summer, she rises to breathe, lifting her black snout through the surface of the waters. Then she draws fresh air into her lungs, flavoured with leaves and flowers, and after she has breathed it in she lets go the last bubble of the breath she drew from the summer of the year before; and it is this bubble of breath alone that will give back life to the five senses of Princess Melilot. But the Worm's time for rising is far; and how you shall bear the weight in the depths of those waters, or make the Worm give up the bubble before her time, or at last bear back the bubble to lay it on the lips of the Princess so that she may wake,--these are things I know not the way of, for to my eyes they seem dark with difficulty and peril.' Then Noodle, opening the petals of the Burning Rose as it lay upon the heart of Melilot, drew out honey from its centre, filling his hand with the golden crumblings of fragrance; and he leapt upon the Galloping Plough, urging it in the way the Princess's nurse had pointed out to him. As they went he caressed it with all the names under heaven, stroking it with his hand and praising it for the delicacy of its steering: saying, 'O my moonbeam, if thou wouldst save the life of thy master, or restore the five senses of the Princess Melilot, thou must surpass thyself to-day. Listen, thou heaven-sent limb, thou miracle of quicksilver, and have a long mind to my words; for in a short while I shall have no speech left in me till the thing be done, and the deliverance, from head to feet, of my Beloved accomplished.' Even while he spoke they came to the edge of the Bitter Lake--a small pool, but its waters were blacker than night, and heavier than lead to the eye. Then Noodle leapt down from the Plough, and caressed it for the last time, saying: 'Set thy face for the garden where the Princess Melilot is; and when I am come back to thee speechless out of the Lake and am striding thee once more, then wait not for a word but carry me to her with more speed than thou hast ever mustered to my aid till now; go faster than wind or lightning or than the eye of man can see! So, by good fortune, I may live till I reach her lips; but if thou tarry at all I am a dead man. And when thou art come to Melilot set thy share beneath the roots of her feet, and take her up to me out of the ground. Do this tenderly, but abate not speed till it be done!'
