“It is of great age and of immense value,” said Professor Andreas. “Without being able to make an absolute assertion, we have many reasons to think that it is possible that it may be the original urim and thummim of Solomon’s Temple. There is certainly nothing so fine in any collection in Europe. My friend, Captain Wilson here, is a practical authority upon precious stones, and he would tell you how pure these are.” Captain Wilson, a man with a dark, hard, incisive face, was standing beside his _fiancée_ at the other side of the case. “Yes,” said he, curtly, “I have never seen finer stones.” “And the gold-work is also worthy of attention. The ancients excelled in ——”—he was apparently about to indicate the setting of the stones, when Captain Wilson interrupted him. “You will see a finer example of their gold-work in this candlestick,” said he, turning to another table, and we all joined him in his admiration of its embossed stem and delicately ornamented branches. Altogether it was an interesting and a novel experience to have objects of such rarity explained by so great an expert; and when, finally, Professor Andreas finished our inspection by formally handing over the precious collection to the care of my friend, I could not help pitying him and envying his successor whose life was to pass in so pleasant a duty. Within a week, Ward Mortimer was duly installed in his new set of rooms, and had become the autocrat of the Belmore Street Museum. About a fortnight afterwards my friend gave a small dinner to half-a-dozen bachelor friends to celebrate his promotion. When his guests were departing he pulled my sleeve and signalled to me that he wished me to remain. “You have only a few hundred yards to go,” said he—I was living in chambers in the Albany. “You may as well stay and have a quiet cigar with me. I very much want your advice.” I relapsed into an arm-chair and lit one of his excellent Matronas. When he had returned from seeing the last of his guests out, he drew a letter from his dress-jacket and sat down opposite to me. “This is an anonymous letter which I received this morning,” said he. “I want to read it to you and to have your advice.” “You are very welcome to it for what it is worth.” “This is how the note runs: ‘Sir,—I should strongly advise you to keep a very careful watch over the many valuable things which are committed to your charge. I do not think that the present system of a single watchman is sufficient. Be upon your guard, or an irreparable misfortune may occur.’” “Is that all?” “Yes, that is all.” “Well,” said I, “it is at least obvious that it was written by one of the limited number of people who are aware that you have only one watchman at night.”
