Latitude, 5 deg. 5' 55" south; longitude, 75 deg. 59' 58" west of Greenwich; magnetic variation, 7 deg. 47' east; thermometer, 77 deg.; elevation above sea-level, 440 feet; distance from the Atlantic, 2554 miles; current, 3-1/4 miles per hour. The advantage which Yurimaguas possesses over all the other river ports on the Upper Amazon is that of its being the point where travelers from Lima and articles of export from Moyubamba, a city of 10,000 inhabitants, meet the steamers from Para. Canoes ascend the Huallaga from Yurimaguas to Chasuta in eight days and make the return trip in three; from Chasuta there is a mule road to Moyubamba, Chachapoyas and Cajamarca, and from the latter place a railway runs to Lima. This is the best route from the Amazon to the Pacific coast, and the only one which does not involve long marches on foot. Steamers drawing five or six feet of water could make regular trips to Chasuta at any season of the year, even at lowest water, and meeting larger steamers at Yurimaguas would establish better communication with the rich country of the interior. On the Huallaga, above Yurimaguas and a little back from the river, are to be found the best locations for colonies. Thirty miles above Yurimaguas, on the right bank of the river, is situated Shucushiyacu, a place well known as commanding a fine view of mountain and river scenery. CAINARACHI. Distance from the Atlantic, 2592 miles; current, 3-1/4 miles per hour. RUMICALLARINA. Latitude, 5 deg. 58' 32" south; longitude, 75 deg. 47' 32" west of Greenwich; magnetic variation, 8 deg. 8' 10" east; thermometer, 77 deg.; elevation above sea-level, 486 feet; distance from the Atlantic, 2600 miles; current, 3-1/2 miles per hour; depth of water, 36 feet; width of river, 200 yards. Rumicallarina is at the head of navigation for steamers on the Huallaga. Any steamer which can ascend the river to Yurimaguas can continue on to Rumicallarina, beyond which place only five or six feet, at the season of low water, can be carried to Chasuta.
