This part of the island is but an extension of the vast slope of Mauna Kea; and all the waters which drain from its cloud-laden summit pour into the sea through numerous deep channels, or gorges which they have worn for themselves, and occasionally dash into the ocean from high cliffs, forming water-falls visible from the ship's deck.

Of the gorges or canons, there are seventy-nine in a distance of about thirty miles; many of them are from five to eight hundred feet deep; and as you ride along the coast, you have no sooner emerged from one of these deep pits than you descend by a road seldom easy, and often very steep indeed, into another.

The sides of these gorges are lined with masses of the most magnificent ferns, and at their bottoms you find sparkling streams; and as you look up the canons you see picturesque water-falls.

In short, to the lover of bold and strange scenery this ride offers many pleasures; and that its difficulties may not be exaggerated to any one's apprehension, I will mention that during the spring of 1873 an English lady, taking with her only a native woman as guide, made the tour of the whole seventy-nine gulches, and thought herself amply rewarded for her toils by what she saw.

As for myself, I must confess that four of these gulches--the four nearest Hilo--satisfied me; these I saw in visiting some sugar-plantations.
[Illustration: KEALAKEAKUA BAY, WHERE CAPTAIN COOK WAS KILLED.] If you do not intend such a thorough exploration of Hawaii, but mean only to see the volcano of Kilauea, your pleasantest plan is to ride from Hilo by the direct road to the crater, and return by way of Puna.
