"I had no statement to make to her," was the reply.

Dr. Gould told me this story was founded on fact, but when, after Winlock's death, it was put off on me with some alterations, I felt less sure.

The following I believe to be authentic. It occurred several years later. Hilgard, in charge of the Coast Survey office, was struck by the official terseness of the communications he occasionally received from Winlock, and resolved to be his rival. They were expecting additions to their families about the same time, and had doubtless spoken of the subject. When Hilgard's arrived, he addressed a communication to Winlock in these terms:—

"Mine's a boy. What's yours?"

In due course of time the following letter was received in reply:—

Dear Hilgard:—
Boy.
Yours, etc., J. Winlock.

When some time afterward I spoke to Winlock on the subject, and told him what Hilgard's motive was, he replied, "It was not fair in Hilgard to try and take me unawares in that way. Had I known what he was driving at, I might have made my letter still shorter." I did not ask him how he would have done it. It is of interest that the "boy" afterward became one of the assistant secretaries of the Smithsonian Institution.

One of the most remarkable features of the history of the "Nautical Almanac" is the number of its early assistants who have gained prominence or distinction in the various walks of life. It would be difficult to find so modest a public work to exceed it in this respect.

John D. Runkle, who lived till 1902, was, as I have said, the senior and leading assistant in the office. He afterward became a professor in the Institute of Technology, and succeeded Rogers as its president. In 1876 he started the school of manual training, which has since been one of the great features of the Institute. He afterward resigned the presidency, but remained its principal professor of mathematics. He was the editor and founder of the "Mathematical Monthly," of which I shall presently have more to say.

The most wonderful genius in the office, and the one who would have been the most interesting subject of study to a psychologist, was Truman Henry Safford. In early childhood he had excited attention by his precocity as what is now sometimes called a "lightning calculator." A committee of the American Academy of Arts and Science was appointed to examine him. It very justly and wisely reported that his arithmetical powers were not in themselves equal to those of some others on record, especially Zerah Colburn, but that they seemed to be the outcome of a remarkable development of the reasoning power. When nine years old, he computed almanacs, and some of his work at this age is still preserved in the Harvard University Library. He graduated at Harvard in 1854, and was soon afterward taken into the Nautical Almanac Office, while he also worked from time to time at the Cambridge observatory. It was found, however, that the power of continuous work was no greater in him than in others, nor did he succeed in doing more than others in the course of a year.
