On starting out on my first trip among the hoboes, I thought that I had provided myself with a sufficient number of words and phrases to converse with them more or less as one of their own kind; but I soon discovered how little I knew of their language. My stock of slang consisted of expressions taken from dictionaries and acquired in association with gamins of the street, and I was naïve enough to think that it would suffice for companionship with the regular tramps. It is true that the hoboes make use of a great deal of slang that is popular in the streets and not unknown to "respectable" people, but for social intercourse they rely mainly on their own jargon. In Germany, where the police collect tramp and criminal slang into dictionaries, in order that they may be able to understand the conversations of the _Chausséegrabentapezirer_ and _Gauner_, it is less difficult for one to pick up the local tramp lingo; but in the United States there is no dictionary sufficiently up to date to give the beginner much assistance. Martin Luther was one of the first in Germany to take an interest in collecting the vagabond's "cant" phrases. He published in Latin a small volume, called "The Book of Vagabonds," which includes all the tramp slang he could pick up; and ever since the publication of this interesting little work, which is now very rare, German philologists and policemen have printed, from time to time, supplementary dictionaries and glossaries. In all Continental countries the Hebrew and Gipsy languages have been levied upon by the tramps for contributions to their dialects, and even in England the tramp jargon contains a number of words which have been imported from Germany, Bohemia, Russia, and France. In this country, on the other hand, the tramps have relied largely on their own ingenuity for cant phrases, and they often claim that expressions thus invented are much more forcible and succinct than any that they might have borrowed from foreign languages. They think that a good word is as much the result of inspiration as is a successful begging trick; and they believe, furthermore, that America is entitled to a cant language of its own. It is easy to see how this dialect originated. It came into existence primarily as a means of talking in public without being understood by others than those intimately connected with the life. It is also true that some of the words have sprung from those necessities of expression which ignorance and lack of education could not supply. In the United States, as a general rule, thanks to reformatories and prison libraries the majority of tramps are fairly well read, and can speak English with considerable correctness; but it often happens that they have thoughts and feelings which their faulty vocabularies cannot make clear, and they are obliged to invent their own words and phrases.
