In the higher ground--where tropical heath and heather painted the surface with hues of crimson, pink, and purple--snakes wriggled and darted about everywhere.

One cannot help wondering why Nature has taken the pains to paint many of the most deadly of these in colours that rival the hues of the humming-birds that yonder flit from bush to bush, from flower to flower.

Perhaps it is that they may the more easily seek their prey, their gaudy coats matching well with the shrubs and blossoms that they wriggle amongst, while gliding on and up to seize helpless birds in their nests or to devour the eggs.

Parrots here, and birds of that ilk, have an easy way of repelling such invaders, for as soon as they see them they utter a scream that paralyses the intruders, and causes them to fall helplessly to the ground.

To all creatures Nature grants protection, and clothes them in a manner that shall enable them to gain a subsistence; but, moreover, every creature in the world has received from the same great power the means of defending or protecting itself against the attacks of enemies.

On both sides, then, is Nature just, for though she does her best to keep living species extant until evolved into higher forms of life, she permits each species to prey on the overgrowth or overplus of others that it may live.

Knocking over a heap of soft dry mould with the b.u.t.t end of his rifle, d.i.c.k started back in terror to see crawl out from the heap a score or more of the most gigantic beetles anyone could imagine. These were mostly black, or of a beautiful bronze, with streaks of metallic blue and crimson.

They are called harlequins, and live on carrion. Nothing that dies comes wrong to these monsters, and a few of them will seize and carry away a dead snake five or six hundred times their own weight. My readers will see by this that it is not so much muscle that is needed for feats of strength as indomitable will and nerve force. But health must be at the bottom of all. Were a man, comparatively speaking, as strong as one of these beetles, he could lift on his back and walk off with a weight of thirty tons!

Our heroes had to stop every now and then to marvel at the huge working ants, and all the wondrous proofs of reason they evinced.

It was well to stand off, however, if, with snapping horizontal mandibles and on business intent, any of these fellows approached. For their bites are as poisonous as those of the green scorpions or centipedes themselves.

What with one thing or another, all hands were attacked by healthy hunger at last, and sought the shade of a great spreading tree to satisfy Nature's demands.

When the big basket was opened it was found that Beeboo had quite excelled herself. So glorious a luncheon made every eye sparkle to look at it. And the odour thereof caused Brawn's mouth to water and his eyes to sparkle with expectancy.

The Indians had disappeared for a time. They were only just round the shoulder of a hill, however, where they, too, were enjoying a good feed.

But just as Burly Bill was having a taste from a clear bottle, which, as far as the look of it went, would have pa.s.sed for cold tea, two Indian boys appeared, bringing with them the most delicious of fruits as well as fresh ripe nuts.

The luncheon after that merged into a banquet.

Burly Bill took many sips of his cold tea. When I come to think over it, however, I conclude there was more rum than cold tea in that brown mixture, or Bill would hardly have smacked his lips and sighed with such satisfaction after every taste.

The fruit done, and even Brawn satisfied, the whole crew gave themselves up to rest and meditation. The boys talked low, because Peggy's meditations had led to gentle slumber. An Indian very thoughtfully brought a huge plantain leaf which quite covered her, and protected her from the chequered rays of sunshine that found their way through the tree. Brawn edged in below the leaf also, and enjoyed a good sleep beside his little mistress.

Not a gun had been fired all day long, yet a more enjoyable picnic in a tropical forest it would be difficult to imagine.

Perhaps the number of the Indians scared the jaguars away, for none appeared.

Yet the day was not to end without an adventure.

Darkness in this country follows the short twilight so speedily, that Burly Bill did well to get clear of the forest's gloom while the sun was still well above the horizon.

He trusted to the compa.s.s and his own good sense as a forester to come out close to the spot where he had left the boat. But he was deceived.

He struck the river a good mile and a half above the place where the steamer lay at anchor and the raft aground on the shoals.

Lower and lower sank the sun. The ground was wet and marshy, and the 'gators very much in evidence indeed.

Now the tapirs--and droll pig-bodied creatures they look, though in South America nearly as big as donkeys--are of a very retiring disposition, but not really solitary animals as cheap books on natural history would have us believe. They frequent low woods, where their long snouts enable them to pull down the tender twigs and foliage on which, with roots, which they can speedily unearth, they manage to exist--yes, and to wax fat and happy.

But they are strict believers in the doctrine of cleanliness, and are never found very far from water. They bathe every night.

Just when the returning picnic was within about half a mile of the boat, Burly Bill carrying Peggy on his shoulder because the ground was damp, a terrible scrimmage suddenly took place a few yards round a backwater.

There was grunting, squeaking, the splashing of water, and cries of pain.

"Hurry on, boys; hurry on; two of you are enough! It's your show, lads."

The boys needed no second bidding, and no sooner had they opened out the curve than a strange sight met their gaze.

CHAPTER VI--"NOT ONE SINGLE DROP OF BLOOD SHED"

A gigantic and horribly fierce alligator had seized upon a strong young tapir, and was trying to drag it into the water.

The poor creature had both its feet set well in front, and was resisting with all its might, while two other larger animals, probably the parents, were clawing the cayman desperately with their fore-feet.

But ill, indeed, would it have fared with all three had not our heroes appeared just in the nick of time.

For several more of these scaly and fearsome reptiles were hurrying to the scene of action.

d.i.c.k's first shot was a splendid one. It struck the offending cayman in the eye, and went crashing through his brain.

The brute gasped, the blood flowed freely, and as he fell on his side, turning up his yellow belly, the young tapir got free, and was hurried speedily away to the woods.

Volley after volley was poured in on the enraged 'gators, but the boys had to retreat as they fought. Had they not done so, my story would have stopped short just here.

It was not altogether the sun's parting rays that so encrimsoned the water, but the blood of those old-world caymans.

Three in all were killed in addition to the one first shot. So that it is no wonder the boys felt elated.

Beeboo had supper waiting and there was nothing talked about that evening except their strange adventures in the beautiful forest.

Probably no one could sleep more soundly than did our heroes and heroine that night.

Next day, and next, they went on sh.o.r.e again, and on the third a huge jaguar, who fancied he would like to dine off Brawn's shoulder, fell a victim to d.i.c.k Temple's unerring aim.

But the raft never stirred nor moved for a whole week.

Said Bill to Jake one morning, as he took his meerschaum from his mouth:

"I think, Jake, and w'at I thinks be's this like. There ain't ne'er a morsel o' good smokin' and on'y just lookin' at that fine and valuable pile o' timber. It strikes me conclusive like that something 'ad better be done."

"And what would you propose, Bill?" said Jake.

"Well, Jake, you're captain like, and my proposition is subject to your disposition as it were. But I'd lighten her, and lighten her till she floats; then tow her off, and build up the odd timbers again."
