On October 6, 1829, after three months devoted to reviewing his notes for the opening chapter, he took his noctograph and scrawled the initial sentence.

And so, after a little time, he went on as before, studying "by ear-work," and turning off upon his noctograph from ten to fifteen pages every day.

Prescott, however, had his own opinion on the subject, and, with the single exception which has just been cited, he used his noctograph for composition down to the very end, dictating only his correspondence to his secretary.

It was a contrivance called "the noctograph," meant for the use of the blind.

A person using the noctograph wrote with a sort of stylus of ivory, agate, or some other hard substance upon the blackened paper, which conveyed the impression to the white paper underneath.
