It was plain to see that Walkirk's interest and pleasure increased when my rambling narrations resolved themselves into a series of evening lectures upon Great Britain, the Continent, and the north coast of Africa, and his pleasure was a decided gratification to me. If his engagements and mine had permitted, I should have been glad to talk to him at other times, as well as in the evening.

After a month or more of this agreeable occupation, the fact began to impress itself upon me that I was devoting too much time to the pleasure of being listened to. My grandmother gently complained that the time I gave to her after dinner appeared to be growing less and less, and there was a good deal of correspondence and other business I was in the habit of attending to in the evening which now was neglected, or done in the daytime, when I should have been doing other things.

I was not a man of leisure. My grandmother owned a farm about a mile from our village, and over the management of this I exercised a supervision. I was erecting some houses on land of my own on the outskirts of the village, and for this reason, as well as others, it frequently was necessary for me to go to the city on business errands. Besides all this, social duties had a claim on me, summer and winter.

I had gradually formed the habit of talking with Walkirk on other subjects than my travels, and one evening I mentioned to him some of the embarrassments and annoyances to which I had been subjected during the day, on account of the varied character of my affairs. Walkirk sat for a minute or two, his chin in his hand, gazing steadfastly upon the carpet; then he spoke:—

"Mr. Vanderley, what you say suggests something which I have been thinking of saying to you. I have now finished the catalogue of prints, on which I was engaged when I entered your service as a listener; and my days, therefore, being at my disposal, it would give me great pleasure to put them at yours."

"In what capacity?" I asked.

"In that of an under-study," said he.

I assured him that I did not know what he meant.

"I don't wonder at that," said he, with a smile, "but I will explain. In theatrical circles each principal performer is furnished with what is termed in the profession an under-study. This is an actor, male or female, as the case may be, who studies the part of the performer, and is capable of going through with it, with more or less ability, in case the regular actor, from sickness or any other cause, is prevented from appearing in his part. In this way the manager provides against emergencies which might at any time stop his play and ruin his business. Now, I should like very much to be your under-study, and I think in this capacity I could be of great service to you."

I made no answer, but I am sure my countenance expressed surprise.
