That night there was no rain, and the next day, as the ground was somewhat dry, we commenced a regular survey of the ruins. It was my first essay in engineering. Our surveying apparatus was not very extensive. We had a good surveying compass, and the rest consisted of a reel of tape which Mr. C. had used in a survey of the ruins of Thebes and Jerusalem. My part of the business was very scientific. I had to direct the Indians in cutting straight lines through the woods, make Bruno and Frederico stick their hats on poles to mark the stations, and measure up to them. The second day we were thoroughly in the spirit of it.

That day Don Jose Maria refused to execute the contract. Don Gregorio was the cause. He had ceased to interfere with us, but at the idea of our actually taking root in the neighbourhood he could not contain himself, and persuaded Don Jose Maria that he would get into difficulty by having anything to do with us; he even told him that General Cascara's passport was worthless, and that General Cascara himself had gone over to Morazan. He carried his point for the moment, but in the end we beat him, and the contract was executed.

After three days of very hard but very interesting labour, we finished the survey, the particulars of which I intend to inflict upon the reader; but before doing so I will mention the little that was previously known of these ruins.
