The first study of the Delaware language was undertaken by the Rev. Thomas Campanius (Holm), who was chaplain to the Swedish settlements, 1642-1649. He collected a vocabulary, wrote out a number of dialogues in Delaware and Swedish, and even completed a translation of the Lutheran catechism into the tongue. The last mentioned was published in Stockholm, in 1696, through the efforts of his grandson, under the title, LUTHERI CATECHISMUS, _Ofwersatt pä American-Virginiske Spräket_, 1 vol., sm. 8vo, pp. 160. On pages 133-154 it has a _Vocabularium Barbaro-Virgineorum_, and on pages 155-160, _Vocabula Mahakuassica_. The first is the Delaware as then current on the lower river, the second the dialect of the Susquehannocks or Minquas, who frequently visited the Swedish settlements. Although he managed to render all the Catechism into something which looks like Delaware, Campanius' knowledge of the tongue was exceedingly superficial. Dr. Trumbull says of his work: "The translator had not learned even so much of the grammar as to distinguish the plural of a noun or verb from the singular, and knew nothing of the "transitions" by which the pronouns of the subject and object are blended with the verb."[151] At the close of his "History of New Sweden," Campanius adds further linguistic material, including an imaginary conversation in Lenape, and the oration of a sachem. It is of the same character as that found in the Catechism. After the English occupation very little attention was given to the tongue beyond what was indispensable to trading. William Penn, indeed, professed to have acquired a mastery of it. He writes: "I have made it my business to understand it, that I might not want an interpreter on any occasion."[152] But it is evident, from the specimens he gives, that all he studied was the trader's jargon, which scorned etymology, syntax and prosody, and was about as near pure Lenape as pigeon English is to the periods of Macaulay. An ample specimen of this jargon is furnished us by Gabriel Thomas, in his "Historical and Geographical Account of the Province and Country of Pensilvania; and of West-New-Jersey in America," London, 1698, dedicated to Penn. Thomas tells us that he lived in the country fifteen years, and supplies, for the convenience of those who propose visiting the province, some forms of conversation, Indian and English. I subjoin a short specimen, with a brief commentary:--
