Enclosure 7.
Mr. Percy Smith to Mr. E. T. Brissenden.
My dear Mr. Brissenden,—
In accordance with your request I enclose you herewith a rough description of the blocks now under negotiation by you.
In some few cases I have been obliged to trust to information derived from the surveyors, but generally speaking the information is from my own observations. Trusting that it may be of service to you,
I remain, &c.,
S. Percy Smith,
Chief Geodetic Surveyor.
