world" that read "1 ... 2 ... 3 ...". Reporters treated it as a sensational story and jumped to the conclusion Tesla was hearing signals from Mars. He expanded on the signals he heard in a 9 February 1901 Collier's Weekly article "Talking With Planets" where he said it had not been immediately apparent to him that he was hearing "intelligently controlled signals" and that the signals could come from Mars, Venus, or other planets. It has been hypothesized that he may have intercepted Marconi's European experiments in July 1899—Marconi may have transmitted the letter S (dot/dot/dot) in a naval demonstration, the same three impulses that Tesla hinted at hearing in Colorado—or signals from another experimenter in wireless transmission. On 7 January 1900 Tesla made his final entry in his journal while in Colorado Springs. In 1904 Tesla was sued for unpaid bills in Colorado Springs, his lab was torn down in that year, and its contents were sold two years later in an auction at the court house to satisfy his debts. Location The Experimental Station was located on empty land on the highest local point (Knob Hill) between the 1876 Colorado School for the Deaf and Blind and the Union Printers Home, where Tesla conducted the research described in the Colorado Springs Notes, 1899-1900. A few papers of the times listed Tesla's lab as about 200 feet east of the Deaf and Blind School and 200 feet north of Pikes Peak Avenue. This put it on top of the hill at E. Kiowa Street and N. Foote Avenue (facing west), as documented by Pikes Peak Library District.
