It is a fact somewhat surprising, as well as unfortunate, that no complete grammar of any language of the Huron-Iroquois stock has ever been published. Many learned and zealous missionaries, Catholic and Protestant, have labored among the tribes of this stock for more than two centuries. Portions of the Scriptures, as well as some other works, have been translated into several of these languages. Some small books, including biographies and hymn-books, have been composed and printed in two of them; and the late devoted and indefatigable missionary among the Senecas, the Rev. Asher Wright, conducted for several years a periodical, the "Mental Elevator" (_Ne Jaguhnigoageswatha_), in their language. Several grammars are known to have been composed, but none have as yet been printed in a complete form. One reason of this unwillingness to publish was, undoubtedly, the sense which the compilers felt of the insufficiency of their work; Such is the extraordinary complexity of the language, such the multiplicity of its forms and the subtlety of its distinctions, that years of study are required to master it; and indeed it may be said that the abler the investigator and the more careful his study, the more likely he is to be dissatisfied with his success. This dissatisfaction was frankly expressed and practically exhibited by Mr. Wright himself, certainly one of the best endowed and most industrious of these inquirers. After residing for several years among the Senecas, forming an alphabet remarkable for its precise discrimination of sounds, and even publishing several translations in their language, he undertook to give some account of its grammatical forms. A little work printed in 1842, with the modest title of "_A Spelling-book of the Seneca Language_," comprises the variations of nouns, adjectives and pronouns, given with much minuteness. Those of the verbs are promised, but the book closes abruptly without them, for the reason--as the author afterwards explained to a correspondent--that he had not as yet been able to obtain such a complete knowledge of them as he desired. This difficulty is further exemplified by a work purporting to be a "_Grammar of the Huron Language, by a Missionary of the Village of Huron Indians, near Quebec, found amongst the papers of the Mission, and translated from the Latin, by the Rev. John Wilkie_." This translation is published in the "_Transactions of the Literary and Historical Society of Quebec_," for 1831, and fills more than a hundred octavo pages. It is a work evidently of great labor, and is devoted chiefly to the variations of the verbs; yet its lack of completeness may be judged from the single fact that the "transitions," or in other words, the combinations of the double pronouns, nominative and objective, with the transitive verb, which form such an important feature of the language, are hardly noticed; and, it may be added, though the conjugations are mentioned, they are not explained.
