To his success in this instance referred to may be attributed the series of wonderful articles which constitute "Knots Untied;" for had he failed on that occasion, it is probable that he would never have had confidence to attempt again the critical _rôle_ which the successful detective must necessarily play; and the literature of the age would therefore have lacked the charming contribution of the mysterious revelations of hidden life which Mr. McWatters has made in these spirited tales. It would be pleasing to the writer to make allusion here in detail, somewhat, to that incident, and other affairs in which Mr. McWatters became engaged, and which have come to the writer's knowledge, but which Mr. McWatters has not seen fit to reveal in "Knots Untied;" but it would, perhaps, be an unwarranted act to do so. He has conceived the design of the book to suit his own tastes, of course; and while he has in these articles struck a chord which cannot but awaken in the popular mind a rich responsive appreciation of his book, yet he cannot expect to suit everybody's taste in every respect. MR. MCWATTERS AS AGENT AND LECTURER. It is not attempted here to give the current of Mr. McWatters' life as it occurred, in successive steps; indeed, the writer is not sure in respect to dates in all cases, possessing only the facts in substance. But not long after Mr. McWatters' first engagement with Miss Keene was determined, he became the exhibiting lecturer accompanying a grand panorama of a "Journey to California by Water and back by Land," and it is not difficult to conceive that with his experiences as a traveller, his residence in California, and his gifts as a public speaker, he made the "Journey" a matter of great delight to his audiences. The panorama was exhibited in the chief cities and towns of various States. Subsequently Mr. McWatters became the agent of the late Countess of Lansfeldt, more generally known as Lola Montez, which he continued to be until nearly the time of her death. Much has been written about Lola,--much which is false, as well as much which is true. She was, in some respects, particularly social ones, a great woman, but had her weaknesses, like other mortals. Lola, like many, was inclined to occasional religious fits; and this fact suggests an incident worthy of recital, since it illustrates something of the life of persons of much public note.
