Existing procedures have been considered and new techniques, including a method for the estimation of propagule numbers, are presented. This paper shows the diversity of the communities which may exist in an area of less than 1 km.2; further evidence has been provided on the constancy of these communities. From previous work distribution patterns of a mosaic type were expected; the present results suggest that several orders of such patterns exist, ranging from those within a core of soil about 5 cm. in diameter, through those of quadrats of 1 m.2, to the production of a continuum several metres or even 100 m. in extent. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/13500872-42-2-257
