CRYPTOGRAPHIC CORRESPONDENCE.
A lady wrote to a gentleman thus:—
“I shall be much obliged to you, as reading alone engages my attention at present, if you will lend me any one of the Eight volumes of the Spectator. I hope you will excuse this freedom, but for a winter’s evening I don’t know a better entertainment. If I fail to return it soon, never trust me for the time to come.”
The words successively italicized convey the secret invitation.
