Popayán was reached without further incident. Richardson’s contract having expired, he determined to leave the country, so we returned to Cali to rearrange the equipment and pack the collections; then he left for Buenaventura to take a north-bound steamer.

In the meantime Doctor Chapman, who had reached New York, arranged to send down a man to fill the vacancy left by Richardson. Doctor Arthur A. Allen, of Cornell University, was selected for the place. He reached Cali about the middle of August and accompanied me during the succeeding eight months.

In compliance with instructions received from Doctor Chapman, I immediately planned an expedition northward, then toward the east to make a zoological exploration of the forests bordering the Quindio Pass and of the high paramo of Santa Isabel. The first stage of the journey was down the Cauca River.

Regular steamboat service is maintained between Guanchito and Cartago during the rainy season. The Sucre, a boat of small size, makes frequent voyages, requiring about three days’ time each way. On this vessel one may travel in comparative comfort—if one is not too squeamish. We had to be content with a smaller craft, however, as there was not sufficient water to float the Sucre over the numerous sand-bars.

The Caldas is a little steel launch of not over fifty feet from stem to stern, with a beam of fifteen feet and drawing eighteen inches of water. When the river is full the Caldas is used to carry freight only, for which purpose she doubtless serves admirably; but at other times she assumes the double responsibility of carrying both cargo and passengers. Of course there is the alternative of going overland; but the trip takes twice as long, and after having spent some time on the muddy trails, the novelty of a river trip is likely to make a strong appeal, whatever the odds.

On the announced date of sailing thirty-seven individuals of all sizes, ages, and shades of color gathered on the river’s bank, each impatient to be the first to cross the narrow plank and board the small craft. There also waited a huge mound of boxes, bags, bales of hides, and other freight; this was loaded first and piled in the front and rear. The engine occupied the centre of the boat, as did the kitchen. When the people were finally permitted to go aboard, there was a wild scramble to the top of the heap of boxes and bundles. To sit up straight under the sheet-iron roof was impossible; fortunately the sun shone intermittently only or we should have been suffocated.

From the very beginning there was enough of interest to keep one’s nerves tensed to a high pitch. The crumbling banks, great chunks of which settled gently into the water as the waves, caused by the launch’s propeller, washed away the last bit of restraining sand; the numbers of bamboo rafts laden with bananas, plantains, and other tropical fruits on their way to the port of Guanchito; the dark-skinned fishermen who cast their nets into eddies and quiet pools, and the washwomen, each smoking an enormous black cigar and beating the clothes upon stones until one expected to see them fly into shreds, were very interesting. There were also hundreds of cormorants and anhingas that swam and dived or flew up into the trees; some of them sat on snags drying their wide-spread wings.

The banks of the river are very high and abrupt in most places, and the stream runs through a tortuous channel. At each bend the current dashes with great force against the bank, and then rebounds on down-stream. The little Caldas could not hope to battle against the rushing torrent, so she would head straight for the bank; frequently her nose struck the soft sand and held fast; then the current swung her around and back into midstream, where after spinning around a few times she regained her poise and was swept along. As wood was burned exclusively, stops had to be made every few hours for a new supply. The launch, in her crowded condition, had little room for fuel, but the brief pauses gave those on board an opportunity to go ashore—a welcome respite from the cramped position made necessary by the limited space available on the boat. At one of these spots an extensive cacao-plantation lined the bank, the tall madres de cacao reaching high up into the heavens above their lowly but precious protégés. The “mother of cacao,” it might be said, is a species of Erithmas planted to protect the delicate cacao-trees from the sun. A colony of snake-birds or anhingas had selected this grove for a rookery. Thousands of the birds sat on the topmost branches while other countless numbers were flying back and forth in endless streams, each bird a component part of a whirling, living mass. The slender body, long thin neck, small head, and sharp bill give the bird a peculiar appearance; when swimming under water with only the neck protruding it greatly resembles a snake—hence the name snake-bird. Each tree within an area of several acres contained a number of nests; they were clumsy structures made of sticks. The eggs, three or four in number, are white and as long as a hen’s egg but only half as wide. Later in the day a flock of scarlet ibises approached from down-stream, flew past, and then disappeared like twinkling bits of flame.

In the early afternoon the Caldas struck a sand-bar with full force. The greater number of the passengers had eaten their luncheon—brought by themselves in small parcels neatly done up in banana leaves—and were quietly dozing. There was a harsh, grating sound, a shock, and the water swirled around and past the boat, which moved not an inch. The engines were reversed and the crew sprang into the river and pushed, but it availed nothing, so after repeated efforts these attempts were abandoned. Luckily, the craft carried a small dugout canoe, into which the passengers were unloaded, three or four at a time, and taken ashore by two husky negroes who waded to the bank, one pulling and the other pushing the canoe. There was no break in the abrupt banks for perhaps a quarter of a mile, so it was some time before all on board had been landed. The crew then began to dig away the sand that held the launch fast.

The spot where the passengers had been landed was an open, treeless plain with not a shelter in sight. At first the heat of the sun was insufferable; then it began to rain as we had never seen it rain before. No one had a poncho, so there was nothing to do but stand quietly and endure the drenching downpour.
