Greatly interested in these differences--some of them so great that they led me to seek exchanges of light with Englishmen--I looked for some work that would describe and account for them with a show of completeness, and perhaps depict the process of their origin. I soon found that no such work existed, either in England or in America--that the whole literature of the subject was astonishingly meagre and unsatisfactory. There were several dictionaries of Americanisms, true enough, but only one of them made any pretension to scientific method, and even that one was woefully narrow and incomplete. The one more general treatise, the work of a man foreign to both England and America in race and education, was more than 40 years old, and full of palpable errors. For the rest, there was only a fugitive and inconsequential literature--an almost useless mass of notes and essays, chiefly by the minor sort of pedagogues, seldom illuminating, save in small details, and often incredibly ignorant and inaccurate. On the large and important subject of American pronunciation, for example, I could find nothing save a few casual essays. On American spelling, with its wide and constantly visible divergences from English usages, there was little more. On American grammar there was nothing whatever. Worse, an important part of the poor literature that I unearthed was devoted to absurd efforts to prove that no such thing as an American variety of English existed--that the differences I constantly encountered in English and that my English friends encountered in American were chiefly imaginary, and to be explained away by denying them. Still intrigued by the subject, and in despair of getting any illumination from such theoretical masters of it, I began a collection of materials for my own information, and gradually it took on a rather formidable bulk. My interest in it being made known by various articles in the newspapers and magazines, I began also to receive contributions from other persons of the same fancy, both English and American, and gradually my collection fell into a certain order, and I saw the workings of general laws in what, at first, had appeared to be mere chaos. The present book then began to take form--its preparation a sort of recreation from other and far different labor. It is anything but an exhaustive treatise upon the subject; it is not even an exhaustive examination of the materials. All it pretends to do is to articulate some of those materials--to get some approach to order and coherence into them, and so pave the way for a better work by some more competent man. That work calls for the equipment of a first-rate philologist, which I am surely not. All I have done here is to stake out the field, sometimes borrowing suggestions from other inquirers and sometimes, as in the case of American grammar, attempting to run the lines myself.
