Mr. Earl Douglass Missoula, Mont. Dear Sir: Your last letter was some time since. I have delayed replying until I should have sent off the fossils which I promised to return to you. This I did yesterday, my tardiness being in some measure occasioned by waiting to have small green locality labels pasted on the specimens: The specimens returned are contained in two cigar boxes sent by mail which, should reach you about the same time as this letter. In every case where a species was represented by two or more specimens I returned one at least, and usually half. To this there are perhaps two exceptions where two specimens were so unlike that I was doubtful in referring them to the same species. All the crinoids were temporarily retained with your permission, and I sent on nothing from a small collection collected from the Main Divide of the Rocky Mts. These fossils are not very well preserved and I have not identified them specifically
