Excerpt from Hydrography of the American Isthmus One point of interest in the consideration of the Isthmian canal is the strength and persistence of winds, considered as motive force for sailing vessels, and as annoyance to the navigation of the canal and to ships entering and leaving port. The persistence of the trade winds has frequently been mentioned in discussions of the Nicaragua Canal route. In 1898, it being usees sary to take gage readings at Las Lajas, on the western margin of the lake, for transferring the level line across the lake, 8 camp with an observer was established here and the gage height of the lake was observed at 6 and 9 a. M., 12 noon, 3 and 6 p. M. Note of the condi tion of the lake surface was made at each observation, and from January 19, 1898, when the observations began, until the lst of May a heavy surf was beating on the beach at this point at every observa tion, due to the persistence of the trade winds. A few davs of calm occurred in May and at later periods during the rainy season. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
