A group of children living near Boston invented the _cat language_, so called because its object was to admit of free intercourse with cats, to whom it was mostly talked, and by whom it was presumed to be comprehended. In this tongue the cat was naturally the chief subject of nomenclature; all feline positions were observed and named, and the language was rich in such epithets, as Arabic contains a vast number of expressions for _lion_. Euphonic changes were very arbitrary and various, differing for the same termination; but the adverbial ending _ly_ was always _osh_; _terribly_, _tirriblosh_. A certain percentage of words were absolutely independent, or at least of obscure origin. The grammar tended to Chinese or infantine simplicity; _ta_ represented any case of any personal pronoun. A proper name might vary in sound according to the euphonic requirement of the different Christian-names by which it was preceded. There were two dialects, one, however, stigmatized as _provincial_. This invention of language must be very common, since other cases have fallen under our notice in which children have composed dictionaries of such. It would be strange if children who exhibit so much inventive talent did not contrive new games; and we find accordingly that in many families a great part of the amusements of the children are of their own devising. The earliest age of which the writer has authentic record of such ingenuity is two and a half years. Considering the space which our Indian tribes occupy in the imagination of young Americans, it is remarkable that the red man has no place whatever in the familiar and authorized sports. On the other hand, savage life has often furnished material for individual and local amusements. Near the country place of a family within our knowledge was a patch of brushwood containing about forty acres, and furnishing an admirable ground for savage warfare. Accordingly, a regular game was devised. The players were divided into Indians and hunters, the former uttering their war-cry in such dialect as youthful imagination regarded as aboriginal. The players laid ambushes for each other in the forest, and the game ended with the extermination of one party or the other. This warfare was regulated by strict rules, the presentation of a musket at a fixed distance being regarded as equivalent to death. In a town of Massachusetts, some thirty years since, it was customary for the school-girls, during recess, to divide themselves into separate tribes. Shawls spread over tent-poles represented Indian lodges, and a girl always resorted to her allotted habitation. This was kept up for the whole summer, and carried out with such earnestness that girls belonging to hostile tribes, though otherwise perfectly good friends, would often not speak to each other for weeks, in or out of school.
