"I sing tenor," I amplified, for as yet I suspected nothing.

"Very well then," bade the stranger; "are you holding the receiver to your ear?"

"I am."

"Keep it there. And now stand on your head and sing 'Just as I am Without One Plea.'"

I started back astounded. Instantly I divined, in a lightning flash of intuition, that apparently an effort was being made to perpetrate a hoax. In the same moment I arrived at the definite conclusion that the object of that hoax could be none other than myself. For a fleeting period my natural indignation was such that language almost failed me.

Simultaneously I became aware of a sound as of suppressed laughter outside my study window. Releasing my hold upon the receiver which, until then, mechanically I had retained in my grasp, I stepped to my casement and peered out, first looking this way, then that. No one was in sight; I must have fancied I heard something.

When I had in part recovered myself I lost no time in calling up the manager of the exchange, my intent being to explain the entire circumstance to him, with a view to demanding condign punishment of the person in his inspection department, whoever she might be, who with wilful design had sought to debase the organisation of his office to purposes of ill-timed merrymaking. He cut me short to say he had no such testing department whatsoever. From his tone I was impelled to accept his statement as a truthful one, all of which but served to confirm my suspicions without in the least explaining the mystery which at this hour remains unsolved. I am puzzled—nay, more, I am nettled, and did I not possess the power of holding my emotions under a well-nigh perfect control, I would go so far as to say that I have been outright irritated.

April the Twenty-third.—My earlier suspicions stand confirmed. To-day, as I was passing through a corridor of the main building, I twice heard the word "coo-coo" repeated in a sibilant undertone. Spinning upon my heel, I detected a group of our seniors who with difficulty stifled their merriment; and I saw, too, Miss Hamm, her face illumined by a smile, with one hand upraised as though in gentle admonition of them. This helped to explain much. The raillery could not have been intended for me, since already I had passed on. Moreover, none here knows of the experience through which I passed, and the contretemps averted by my own presence of mind. Therefore, it is quite plain that the would-be joker has been playing similar pranks upon others at Fernbridge.

I wonder whether Miss Hamm herself could have been a victim of such outrageous imposition?

Botanized alone this afternoon, feeling strongly the desire for congenial companionship. Why does this longing so frequently beset me when I go forth to commune with Nature in her gentler moods? I know not, unless it be the influence of the vernal season.
