A memorandum prepared by Caldwell, Civil Engineer and Land Agent at Cordova, Mexico, instructs Maurice to call on T. Robinson Rodgers in New York and tell him Caldwell is in good health and is doing well, but has received only three letters from his wife. Maurice is instructed to tell Mr. McMaster that he approves of McMaster's efforts to find homes in Mexico for their friends, and shall continue his office in Cordova to give information and assistance to emigrants. He will make no charge of those who have no means, for others he will make a charge for every letter he answers, and he is fully prepared to make surveys and locations. McMaster may collect these charges, and he will attend to all orders through McMaster. Caldwell gives his qualifications as surveyor and land agent, and offers his services to McMaster. ` P.S. Maurice should ask McMaster to send Caldwell the Freeman's Journal. He adds an open letter to those who plan to emigrate to Mexico. ` In James Alphonsus McMaster Collection. :: I-1-m A.L.S. 4pp. 12mo.
