138 MARTIN RATTLER. It is pleasant to be thus situated, especially when a cool breeze blows the mosquitoes and other insects off the water, and relieves you for a time from their incessant attacks, Martin Rattler found it pleasant, as he thus lay on his back with his diminutive pet marmoset monkey seated on his breast quietly picking the kernel out of a nut. And Barney O’Flannagan found it pleasant, as he lay extended in the bow of the canoe with his head leaning over the edge, gazing abstractedly at his own reflected visage, while his hands trailed through the cool water, and his young dog—a shagey, indescribable beast with a bluff nose and a bushy tail—watched him intently, as a mother might watch an only child in a dangerous situation. And the old, sun-dried, and storm-battered, and time- shrivelled mulatto trader, in whose canoe they were embarked, and whose servants they had become, found it pleasant, as he sat there perched in his little montaria, like an exceedingly ancient and overgrown monkey, guiding it safely down the waters of the great river of the Tocantins. Some months have passed since we last parted from our daring adventurers, During that period they had crossed an immense tract of country, and reached the head-waters of one of the many streams that carry the surplus moisture of central Brazil into the Amazon.
