The crudely drawn cuts which figure in the pages as "The Boy's Illustrations" are exact reproductions of sketches made by a lad in my own family, between eight and nine years old, to whom, with others, the manuscript was read as a sort of test of its quality. Encouraged by the advice of one of the keenest and most sympathetic students of child life in America, I have ventured to give a few of these drawings to the public, as a curious study in the operations of child-mind. I had agreed with myself not to print the Brownie Book until my scientific work upon the spiders was finished, and the manuscript remained untouched until the winter of 1885-6. At that time I seemed to see the nearing end of my studies, and portions of the Brownie-Pixie story were distributed to various artists, among them Mr. Dan. C. Beard and Mr. Harry L. Poore. Some of the illustrations at that time made, appear in the following pages, bearing date 1886. "Tenants of an Old Farm" had now appeared, and was so well received that it was thought advisable to connect this book with that by an "Introductory Chapter" intended for older readers, and which gives the key to the motive of the story. Early in 1886 I recalled all contracts and arrangements for publication, as a prolonged sickness compelled me to drop scientific work and defer the issue of the "American Spiders." On the very day that the binders placed the first finished copy of the third and last volume of that work in my hands, the "copy" of "Old Farm Fairies" went to the printer. H. C. McC. THE MANSE, PHILADELPHIA, _May 21, A. D. 1895._ THE INTRODUCTION. AN INTRODUCTION. [Illustration: pointing finger] This Chapter is for Grownups only. Children will please skip it. THE SCHOOLMISTRESS AND THE FAIRIES. In the south yard of the Old Farm at Highwood there stands a noble Elm tree. Its massive proportions, the stately pose of its furrowed trunk and the graceful outlines of its drooping branches have often drawn my pleased eyes and awakened admiration. There is nothing in Nature that better serves to stir up human enthusiasm than a fine tree; and as our vicinage for miles around abounds in worthy examples of American forest growths, there is ample opportunity for such sentiment to be kept aglow in the hearts of the Tenants at the Old Farm. Yet it must be confessed that there is also occasion at times for a kindling of quite another sort, when the stupidity, perversity, and penuriousness of men wage a vandal war against the noble monarchs of the woods.
