Fri. Aug. 3rd

Ran two mi. of topog. And meandered the Guimaghou River for about a mile. Transit party struck a swamp and only ran 2000 feet. I got through and got into camp by 3:30. Rained a little in P.M. Big cloud of grasshoppers on the hacienda. There is an American ex-soldier on this hacienda working as a foreman at a peso a day.
