Sometimes a tree that had fallen into the water and lay at a convenient angle by the shore afforded the alligator a comfortable couch for his sun-bath. Shall I ever forget the excitement occasioned by the discovery of our first alligator! Not the ancient and honorable crocodile of the Nile was ever greeted with greater enthusiasm; yet our sportsmen had very little respect for him, and his sleep was disturbed by a shower of bullets that spattered upon his hoary scales as harmlessly as rain. Though the alligator punctuated every adventurous hour of that memorable voyage in Nicaragua, we children were more interested in our Darwinian friends, the monkeys. They were of all shades and shapes and sizes; they descended in troops among the trees by the river side; they called to us and beckoned us shoreward; they cried to us, they laughed at us; they reached out their bony arms, and stretched wide their slim, cold hands to us, as if they would pluck us as we passed. We exchanged compliments and clubs in a sham-battle that was immensely diverting; we returned the missiles they threw at us as long as the ammunition held out, but captured none of the enemy, nor did the slightest damage--as far as we could ascertain. Often the parrots squalled at us, but their vocabulary was limited; for they were untaught of men. Sometimes the magnificent macaw flew over us, with its scarlet plumage flickering like flame. Oh, but those gorgeous birds were splashes of splendid color in the intense green of that tropical background! There were islands in this river,--islands that seemed to have no shores, but lay half submerged in mid-stream, like huge water-logged bouquets. There were sand-bars in the river, and upon these we sometimes ran, and were brought to a sudden stand-still that startled us not a little; then we backed off with what dignity we might, and gave the unwelcome obstructions a wide berth. Perhaps the most interesting event of the voyage was "wooding up." A few hours after we had entered the river our steamer made for the shore. More than once in her course she had rounded points that seemed to block the way; and occasionally there were bends so abrupt that we found ourselves apparently land-locked in the depths of a wilderness which might well be called prodigious. Now it was evident that we were heading for the shore, and with a purpose, too. As we drew nearer, we saw among the deep tangle of leaves and vines a primitive landing. It was a little dock with a thatched lodge in the rear of it and a few cords of wood stacked upon its end. There were some natives here--Indians probably,--with dark skins bared from head to foot; they wore only the breech-clout, and this of the briefest. Evidently they were children of Nature.
