“Ordination” as defined by Goodall is “an arrangement of units in a uni‐ or multidimensional order.” The authors have attempted to apply this method of classification to soil profiles. Data concerning three groups of soil profiles were treated separately in order to show the degrees of similarity and dissimilarity between the profiles. Soils of the Miami family and catena were examined in this manner twice, once on the basis of laboratory data and a second time on the basis of current detailed soil profile descriptions. The two treatments gave some strikingly similar results. The third group of soils consisted of 25 soil profiles considered to be representative of as many great soil groups of the world. A three‐dimensional model showing relationships between these profiles illustrates the possibilities of this kind of analysis.
