I am glad to hear from you again and learn how you have been spending the summer. I have been looking for a letter from you ever since my report 154-A came out. This report completes the morainal mapping I have done. The remainder of MN is covered by Bulletins 12, 13, & 14 of the MN Geological Survey and the maps in them. I have sent in a report on MN and adjacent districts to be published as a Professional Paper of USGS, but it may be a long time before it is published. Perhaps you & I will both be gone before it appears. Since coming from AZ we have had our house on the market, but less than half a dozen people have been to see it. There seems to be no activity in real estate here, partly due to a protest by landladies against the building of a dormitory for women students. It has given the impression that Ann Arbor is overbuilt, and the real estate prices previously asked are now considered excessive. The dormitory has just been started and will be completed for use next September. I have had some success in disposing of the reports and periodicals in my library. Have sold the GSA Bulletin, the Journal of Geology, American Geologist, Geophysical Review, National Geographic, Journal of the Washington Academy of Science, Proc. of the National Academy, Proc. AAAS, Wisconsin Academy, Iowa Academy and Indiana Academy of Science. Also Canada Geological Survey, Missouri, Kansas, Nebraska, Oklahoma, Texas, Louisiana, Arkansas, Illinois, Minnesota, Ohio, & New York (Surveys). I still have the Michigan, Wisconsin, Iowa, Indiana, New Jersey, Pennsylvania and the Dakotas (Surveys). I have disposed of the Annual Reports, Geologic Folios and Professional Papers of the USGS, and am looking for a purchaser for the Water Supply Papers, of which I have a complete set of over 600 papers. I think I will dispose of most of the remaining state reports. Some of the reports have gone to DePauw University, some to the KY Geologic Survey, some to the University of Wichita, but a good share of them have been taken by different departments in the University here. It is surprising how little the sale of all these reports has depleted my library shelves. I still have enough to fill the shelves in my study. I had a lot of them in the attic and on the floor in my study as you may remember. I have given away at least one-third of those enumerated, but have realized over $600.00 for those sold. I am glad to have them go to places where they are needed. I shall not need them either here or in Tucson as there are libraries in both places. I am preparing a paper "Problems of the Glacialist" for my retiring address at the AAAS meeting in Des Moines, and will also have a paper in Section E "Problems of the Upper Ohio Drainage". I presume most of the geologists E of the Mississippi will go to Washington for the GSA meeting but I anticipate a fair attendance from the western half of the country. I will be the only geologist from Ann Arbor. If I am in Ann Arbor next spring, I will probably go to the Washington and the National Academy meetings, so do not mind missing the GSA meeting so much. My health has been good thus far so I have not felt a strong urge to go to AZ, and we may stay here this winter. I think we will be moving out there by next fall. If we do not sell the house, we can probably rent it for the school year and then come back here in the hot season from June to September. I shall be interested in reading your paper on "The correlation of Tertiary mountain ranges" if you send me a copy. I think I will have time to read it before the Des Moines meeting. I hope your health will be good enough to attend either the Washington or the Des Moines meeting. It will do you good to meet a lot of men interested in kindred lines.
