one did it again. I should think that crocodile was eight feet long; but don't go and say I measured him, or that this is my outside measurement for crocodiles. I have measured them when they have been killed by other people, fifteen, eighteen, and twenty-one feet odd. This was only a pushing young creature who had not learnt manners.
Still, even if your own peculiar tastes and avocations do not take you in small dug-out canoes into the heart of the swamps, you can observe the difference in the local scenery made by the flowing of the tide when you are on a vessel stuck on a sand-bank, in the Rio del Rey for example. Moreover, as you will have little else to attend to, save mosquitoes and mangrove flies, when in such a situation, you may as well pursue the study. At the ebb gradually the foliage of the lower branches of the mangroves grows wet and muddy, until there is a great black band about three feet deep above the surface of the water in all directions; gradually a network of gray-white roots rises up, and below this again, gradually, a slope of smooth and lead-brown slime. The effect is not in the least as if the water had fallen, but as if the mangroves had, with one accord, risen up out of it, and into it again they seem silently to sink when the flood comes. But by this more safe, if still unpleasant, method of observing mangrove-swamps, you miss seeing in full the make of them, for away in their fastnesses the mangroves raise their branches far above the reach of tide line, and the great gray roots of the older trees are always sticking up in mid-air. But, fringing the rivers, there is always a hedge of younger mangroves whose lower branches get immersed.
At corners here and there from the river face you can see the land being made from the waters. A mud-bank forms off it, a mangrove seed lights on it, and the thing's done. Well! not done, perhaps, but begun; for if the bank is high enough to get exposed at low water, this pioneer mangrove grows. He has a wretched existence though. You have only got to look at his dwarfed attenuated form to see this. He gets joined by a few more bold spirits and they struggle on together, their network of roots stopping abundance of mud, and by good chance now and then a consignment of
