and who now constitute by far the larger portion of the inhabitants of Darien, being found usually in villages along the valleys of the larger streams. In contrast to the Colombian and Indian they are large in stature and make excellent laborers.
The principal villages in Darien, as Yovisa, Pinagana and Real de St. Marie, are inhabited exclusively by the negroes, with the exception of a Spanish judge in each, who exercises great authority. Besides being a judge in civil and criminal cases, he practically controls everything in his particular village, as all contracts for labor are negotiated with him and settlement for services made through him.
Upon reaching Darien the first work assigned me was the survey and exploration of the Pyrrhi river. This survey was made for two purposes: primarily, to determine if any of the country bordering upon it was of a sufficiently desirable character to include it within the grant, and secondly, to secure data for the general topographical map. My instructions were to proceed as far south as latitude 7° 30'. The ascent of the river was made in canoes until the frequency of rapids made it necessary to abandon them, and then the journey was continued on foot, generally wading in the middle of the stream, as the undergrowth was too thick to admit of progress along the banks. Sometimes the water was very shallow; at other times, where it had been backed up by dams of porphyritic rock, it reached above the waist, and near the end of the journey where the river ran between vertical walls of great height it was necessary to swim in order to get beyond this cañon.
The survey of this river was satisfactorily accomplished in about a week. The method adopted for the survey was to take compass bearings and to estimate distances. These courses and distances were plotted as they were taken and thus the topographical and other features could be readily sketched in connection with them. To check and control this work, observations were taken every day at noon with a sextant, on the sun, for latitude and time, and at night circum-meridian altitudes of stars were obtained when possible.
Thus a number of rivers were surveyed—the Maria, Tucuti, Yovisa and other tributaries of the Tuyra. When it was found that a sufficiently correct idea of the country for topographical purposes could not be obtained by simply meandering the water courses, lines or trochas were cut through the forest from stream
