He also wants to resign his post because he is afraid of being murdered by the Indians. Authorities order him to stay, telling him they will send soldiers to reinforce his position. These documents are included as a proof related to the report that follows, which analyzes in detail Escandon's settlement proposal for the seno Mexicano, including his plan of reoccupying las Canoas (also called San Jose Tanguanchin). Special attention is given to the possibility of exploiting several resources in the area, as salt (describing a method for its extraction), wood (for boat-making), minerals, etc. The strategic advantages of the enterprise, its impact upon the communications network, and its financial cost for the real hacienda, are all carefully analyzed. In the final part, the concrete steps that are necessary to take for the execution of the project are considered. (A. Nielsen, November 1989)
