Another common experience is the crossing of letters. One person suddenly recollects “So-and-so;” and writes them a letter excusing delay in writing, retailing news, and in all probability writing on some subject more particularly than on others. Strange to say, the person you have written to, has also been engaged writing to you about the same time and on similar subjects. Both have possibly posted their letters at such a time that the delivery has been crossed. I do not say this proves anything; yet I cannot help thinking the experience is too frequent to be accounted for by the usual explanation of accident or coincidence. Mark Twain’s article on “Mental Telegraphy” is fresh in the minds of most magazine readers. Whether that article had a basis in the writer’s actual experience or not, it is a pretty common experience with most literary men. “Distance,” says Mr. Tuttle, “has inappreciable influence on the transference of thought. It may take place in the same room, or where the two persons are thousands of miles apart. As a personal experience, I will relate one of many similar incidents which have awakened my attention to this wonderful phenomenon. Sitting by my desk one evening, suddenly as a flash of light, the thought came to write an article for the _Harbinger of Light_, published at Melbourne, Australia. I had, by correspondence, become acquainted with the editor, W. H. Terry, but there had been no letters passed for many a year. I had not thought of him or his journal for I do not know how long a time, and I was amused at first with the idea of writing on the subject suggested. But the impression was so strong that I prepared and forwarded an article. Nearly two months passed before I received a letter from Mr. Terry, requesting me to write an article on the subject on which I have written; and, making due allowance for time, the date of our letters were the same. In our experience, this crossing of letters answering each other has twice occurred--the second by Mr. Terry answering a request of mine.”
