Whenever a new idea presented itself to his mind he used to make a note of it; he even invented a system by which he could take notes in the dark, if some happy thought or ingenious problem suggested itself to him during a sleepless night. Like most men who systematically overtax their brains, he was a poor sleeper. He would sometimes go through a whole book of Euclid in bed; he was so familiar with the bookwork that he could actually see the figures before him in the dark, and did not confuse the letters, which is perhaps even more remarkable.
Most of his ideas were ingenious, though many were entirely useless from a practical point of view. For instance, he has an entry in his Diary on November 8, 1872: "I wrote to Calverley, suggesting an idea (which I think occurred to me yesterday) of guessing well-known poems as acrostics, and making a collection of them to hoax the public." Calverley's reply to this letter was as follows:--
My dear Sir,--I have been laid up (or laid down) for the last few days by acute lumbago, or I would have written before. It is rather absurd that I was on the point of propounding to you this identical idea. I realised, and I regret to add revealed to two girls, a fortnight ago, the truth that all existing poems were in fact acrostics; and I offered a small pecuniary reward to whichever would find out Gray's "Elegy" within half an hour! But it never occurred to me to utilise the discovery, as it did to you. I see that it might be utilised, now you mention it--and I shall instruct these two young women not to publish the notion among their friends.
This is the way Mr. Calverley treated Kirke White's poem "To an early Primrose." "The title," writes C.S.C. "might either be ignored or omitted. Possibly carpers might say that a primrose was not a rose."
Mild offspring of a dark and sullen sire! Whose modest form, so delicately fine, Wild Was nursed in whistling storms Rose And cradled in the winds!
Thee, when young Spring first questioned Winter's sway, And dared the sturdy blusterer to the fight, W a R Thee on this bank he threw To mark his victory.
In this low vale, the promise of the year, Serene thou openest to the nipping gale, Unnoticed and alone I ncognit O Thy tender elegance.
