tions at the fignal of Milin, where they continued till the 7th, when they left it, having 

 completely finifhed their operations. 



XIL — Signal on the Defert of Chulapu. 



From Milin they proceeded to the defert of Chulapu, where they remained till the 

 1 8th of September, when they had finifhed all their obfervations. Till this fignal, 

 exclufive, each company had obferved the three angles of all the triangles ; both be- 

 caufe they differed from one another, and to prove by this precifion the errors in the 

 divifions of the quadrants, before obferved by other methods. But from this fignal, 

 inclufive, each company obferved two angles only of the other triangles, as had been 

 agreed on. * 



XIII. — Signal in Jivicatfu. 



In Jivicatfu they remained from the i8th to the 26th of September. This flation 

 was one of the mofl agreeable ; for, befides the height on which the fignal was erefted, 

 the temperature of the air, and the cheerful afpedt of the country, the town of Pilaro 

 was in the neighbourhood, fo that they wanted for nothing. 



XIV. XV. — Signals on the Deferts of Mulmul and Guayama. 



Thefe two deferts are placed together, becaufe their fummits are united by gentle 

 eminences ; on one of which is a cow-houfe, ufed by the Indians when they go in 

 fearch of their cattle, which feed on the fides of this mountain. In this cow-houfe 

 Don George Juan, M. Godin, and their attendants, took up their quarters on the 

 30th of September, and every morning, when the weather was favourable, repaired 

 to the fignal ere£ted on one or other of the eminences. But the diftance between the 

 two flations being very fmall, and the obfervations made there requiring to be verified 

 by thofe of other auxiliary triangles, it was abfolutely neceffary to determine exadly 

 the flations where thefe triangles were to be formed ; and to remain there till the 

 diftances were fettled, and the obfervations relating to them concluded ; which opera- 

 tions, notwithflanding the greatefl diligence was ufed, employed them till the 20th of 

 October. 



Every thing at the two preceding ftations being finifhed, they repaired to the village 

 of Riobamba, determining to continue their work without interruption ; but meeting 

 with fome difficulties concerning the mofl advantageous pofition of the fubfequent 

 triangles, and money beginning to grow fliort with our whole fociety, both Spaniards 

 and French, it was thought neceffary to make ufe of the interval while the proper 

 places for ere£ling the fignals were determining, to procure fupplies. Accordingly, 

 M. Godin and Don George Juan again fet out from Riobamba for Quito on the 7th of 

 November ; but it was the 2d of February following before we had the pleafure of con- 

 gratulating them on their return, the former having been feized with a fever, which 

 brought him very low, and detained them a confiderable time at Quito. 



' XVI. XVII. — Signals on Amula and Sifa-pongo. 



The obfervations neceffary at the fignal of Amula were finifhed before the journey to 

 Quito; and from the 2d of February 1739, when they returned to Riobamba, till the 

 19th, they were employed in thofe relating to Sifa-pongo.
