Doubt of the real facts, as I must reveal them, is inevitable; yet, if I suppressed what will seem extravagant and incredible, there would be nothing left. The hitherto withheld photographs, both ordinary and aerial, will count in my favor, for they are damnably vivid and graphic. Still, they will be doubted because of the great lengths to which clever fakery can be carried. The ink drawings, of course, will be jeered at as obvious impostures, notwithstanding a strangeness of technique which art experts ought to remark and puzzle over.
