Dolores, N. M. Dec. 18, 1900. Mr. T. A. Edison, Orange, N. J. Mr. T. A. Edison, Orange, N. J. Dear Mr. Edison :- According to your instructions the work on Cunningham Mesa has been stopped, with the shafts in the following condition : - Shaft #15 112 ft, to bedrock, # #16 111 1/2 ft. deep not to bedrock. " #17 76 " " " " " " #18 32 1/2 " " " " " #19 113 " " " " " " #20 29 " " " " " #21 104 1/2 " " " " " #22 59 " " " " " #23 37 1/2 " " " " " " #24 35 " " " " " " #25 20 " " " " The last results of assays are inclosed on a separate sheet. We also inclose map of the Cunningham Mesa with the shafts which we have sunk plainly marked and opposite each one the depth and value of the same. It has been decided that John will return to the Laboratory and will leave here Sunday night. We have taken the privilege of going on a trip to Grand Canon Ariz. for three days, before John's return. We hope that this will meet with your approval. We have started work on the Carachie replacer and inclose the combined result of small samples taken when we examined the ground roughly. This is just a preliminary sample. <Only [fox?> [TAE Marginalia] We have outlined in red on the accompanying map an area that we think might average 15 cts. per yd. The small inclosed area to be excluded. This gives an area of about 10 squares and at an average depth of 30 ft. would give 2,800,000 cu. yds. This estimate must necessarily be more or less guess work on account of the very uneven distribution of the shafts within the area. We consider this a liberal estimate. Yours truly, Cloyd M. Chapman, John V. Miller Accompanying Report of Dec. 18 _ 00. [TABLE LISTING SHAFT SAMPLES AND REMARKS] Accompanying Report of Dec. 18 _ 00. [TABLE LISTING SHAFT SAMPLES AND REMARKS]
