Total, forty-six days. In the interval which remains to complete the three 

 months, there is sujEcient time to reach Spain by the Azores islands. Father 

 Manuel Sobreviela, on the authority of the information communicated to him by 

 Don M. Molina, a distinguished merchant, asserts, in a relation of the progress of 

 the missions of Ocopa, printed at Lima in 1790, before he set out on his expedi- 

 tion, that the return to Lima may be performed in pretty nearly the same time. 

 Experience has demonstrated, however, that at least double the time is required 

 from Para ; seeing that the navigation, in following the course of the waters, is at 

 the rate of from two to three leagues per hour ; while, in navigating against the 

 stream, three quarters of a league only can be performed in the same space of 

 time. But this observation merely applies to an inconsiderable part of the 

 youte. 



The communication the above expedition opens with Manoa^ the restoration of 

 which was its principal objeft, will be elucidated at the close of the peregrination 

 of father Narciso Girbal by the Ucayali, which now follows.
