It has become part of his creed that his country is one of the richest on the globe, and this conviction is so strong that an adverse report upon Honduranean mining property is regarded with scorn and Mining the engineer with commiseration.

This property, which has been worked for a number of years, is well known to readers of the ENOiNEERiNa and Mining Journal. The amount of its dividends are not known, but are said to have been large.
