The theoretical significance of a proposed computer program for the automation of discovery procedure in linguistics is first discussed. An outline is then presented of a type of heuristic computer program which would be suitable for the automation of the procedures employed in the initial phases of field work, particularly during the elicitation of paradigms. The basic characteristics of the trial and evaluation routines to be used in such a program are set forth. Finally, the basic assumptions underlying the proposed computer simulation of informant work are discussed.

The Proto-Algonquian word for ‘grandchild’ has harbored subtle problems of reconstructive detail for Algonquianists. The Ojibwa and Menomini forms disagree, but do not warrant setting up a fresh phonetic correspondence. On the basis of new Ojibwa data, a fresh solution is offered which actually inheres in the data already known. Given the protoform *n(e)-Hōšihsema, an explanation follows naturally from the respective formations of diminutives in Ojibwa and Menomini. The problem is submitted as illustrating a point of non-superficial reconstruction, having interest for general theory.

A new analysis of the Norwegian (and Swedish) word tones is presented, according to which Accent I is regarded as the unmarked member and is identified with primary stress, while Accent II is regarded as the only distinctive tone. The problem of functional burden is explored, and it is suggested that the relatively low importance of tone in communication is due to its structural dependence on the placement of stress. Rules are proposed for the distribution of tone, bringing out the invalidity of most of the minimal pairs presented in previous studies. It is shown that tone is a feature of the post-tonic syllable, and that its presence in the native and much of the borrowed vocabulary is determined by the morphology; in other vocabulary items, the occurrence of tone is highly arbitrary, being lexically and dialectically determined, with virtually no minimal pairs possible.

The continuing relevance of Bernard Bloch's ‘Postulates for phonemic analysis’ lies in the facts that they point to the basis of the minimal-pair identification test, the most powerful tool in phonological analysis, and that they further point to the basic necessity of sound-discrimination in the development of human language.

This paper contains no new information; it is merely an attempt to present, economically and clearly, one small portion of the design of the Yawelmani dialect of Yokuts. The implication is that the rest of the language could also be discussed in the relatively simple way demonstrated here. Newman's description (1944, 1946), from which I draw the facts, is notable for its sensitivity and realism, but is exasperatingly difficult to follow. However, if a more straightforward presentation is now possible, this is perhaps because we have developed some techniques of analysis and of statement not available to Newman three decades ago.
