^^6 ULLOA*S VOYAGE- TO SOUTH AMElllCA. 



Juan and Mr. Godin were on the deferts of Yllahalo and Pambamarca, at the fame time 

 with Meff. Bouguer and Condamine and myfelf. 



I. II. — Signals en the Extremities of the Bafe of Yaruqui. 



In order to make the neceflary qbfervations relating to thefe two fignals, they left 

 Quito on the 20th of Auguft 1737, and had completely finifhed them by the 27th. 



III. — Signal on the Defer t of Pambamarca.. 



After they had concluded all the neceflary obfervations at the extremities of the bafe, 

 they went >vithout delay to the defert of Pambamarca, and completely finifhed their 

 operations by the firfl of September. 



IV. — Signal on the Mountain of Tanlagua. 



Having finifhed their obfervations on the defert, they came down to the little totvn of 

 Quenche, in that neighbourhood, in order to proceed from thence to Tanlagua ; but 

 the Indians, who were to accompany them, being no flrangers to the extreme feverity 

 of the weather on that defert, difcouraged by their recent fufferings on Pambamarca, 

 and knowing they fhould Itill fufFer more on Tanlagua, were not to be found 5 and the 

 lowefl clafs of inhabitants in the town, apprehending that they fhould be fent on this 

 painful fervice, alfoleft their habitations and abfconded ; fo that the joint endeavours of 

 the alcalde and prieft to difcover them proved ineffeftual ; and after a delay of two whole 

 days, the curate, with great difficulty, prevailed on the facriflan, and other Indians em- 

 ployed in the fervice of the church, to accompany them, and take care of the loaded 

 mules as far as the farm-houfe of Tanlagua, where they arrived the 5th of September. 

 The next day they began to afcend the mountain, which, being very fteep, took them 

 up a whole day in climbing it. But this being more than the Indians were able to per- 

 form, as they carried the field-tents, baggage, and inftruments, they were obliged to 

 flop half way ; fo that thofe on the top were under a neceffity of paffing the night 

 there without any fhelter ; and a hard frofl coming on, they were almofl perifhed with 

 cold ; for they were fo greatly affeded by it, that they had no ufe of their limbs till 

 they returned to a warmer air. After all thefe hardfhips, the gentlemen could not finifh 

 their obfervations, fome of the fignals being wanting, having either been blown down 

 by the winds, or carried away by the Indian herdfmen : fo that, during the interval, 

 while perfons were employed in erefting others, they returned to Quito, and applied 

 themfelves to examine the divifions of the quadrants. Thefe operations, being very 

 tedious, employed them till the month of December, when, all the fignals which were 

 wanting being replaced, they again, on the 20th of December, repaired to their poft at 

 Tanlagua; and on the 27th finifhed the obfervations neceflary to be made at that 

 flation. 



V. — Signal on the Mountain of Guapulo. 



The fignal of Guapulo being ereded on a mountain of no great height, and in the 

 neighbourhood of Quito, their refidence was not neceffary ; for, by fetting out from the 

 city at day-break, they could reach the field tent, where the inftruments were left, early 

 in the morning. Thefe journeys repeated every day, and though every moment of 

 time was improved to the greateft advantage, it was the 24th of January 1738 before
