The mathematical calculations. though, are less frequently r eproduced t han the supplementary diagrams (drawn, Thiinen tells us, by an u nnamed ' friend o f m ine'), which appear in standard economic geography texts. The most well k nown is in fact a c ombination o f two (Figure 2.2). The top portion o f this famous depiction describes the rings o f agriculture that surround the central town. The lower p art i ntroduces two factors that disturb the concentric pattern. O ne is a navigable river along which the rings form and the second is a small town, which has its o wn agricultural hinterland.

T he d iagram indicates c oncentric rings o f v arying w idths a round t he t own, each c ontaining a d ifferent agricultural use. The rings, their definition a nd c ontent, were derived from applying calculative logic based o n t he concept o fland r ent b ut s upplemented by other considera­ tions such as soil fertility. T hilnen identified six rings: First ring: H ere 'free cash cropping' will occur. This is e ssentially w hat w e k now as m arket g ardening: t he c ultivation o f ' delicate' fruits a nd vegetables such as strawberries a nd lettuce. Thilnen also assigned dairying to this ring. Milk production, h e reasoned, is c omplementary to market gardening as c attle can be kept intensively ­ eating c ut clover a nd left over vegetables i n stalls rather t han n eeding extensive grazing pastures. The l and r ent in this ring is h igh and, w ith t he application o f a dditional manure, soil fertility can be raised, eliminating the need for fallow periods. Second ring: This is t he zone o f forestry in which w ood a nd charcoal for fuel a nd t imber for urban construction are sourced from managed forests. I n T hilnen's time, wood was the major fuel for townspeople as well as those i n t he c ountryside. T hird ring: This is a relatively narrow ring in w hich d ie 'crop alternation system' prevails. Grain crops (such as rye) a nd feed crops (such as clover) alternate a nd t here is n o fallow period. The soil is e nriched t hrough the applica­ tion o f m anure. Thilnen spent a considerable part o f his b ook discussing the various systems o f c rop alterna­ tion e merging i n n orthern E urope a nd p redicted t hat over time innovative crop rotation systems w ould be widespread. I n t he initial model, though, they occupy a small band. F ourth ring: The ' improved system' is p racticed i n this ring. Here, arable l and is used in t urn for grain a nd r oot crop cultivation a nd for pasture. Fields are periodically left fallow a nd fertilized w ith m anure. Fifth ring: Here the traditional three-field system is prevalent. Fields rotate from arable to pasture to fallow. Sixth ring: Stock farming. This ring is t oo far from the town for grain cultivation as t he t ransport costs w ould o utweigh revenue generated from its sale (see Figure 2.1). However, T hilnen p oints o ut t hat i f t he g rain were distilled a nd c onverted to a lcohol- a higher value product - it could be transported profitably to market. Further­ more, in this zone by-products o f the distilleries could be used for animal feed. Animals are grazed extensively i n this zone, w ith t heir wool a nd m eat sold i n t he t own . Thilnen predicted t hat as t he e conomy prospered, working m en a nd w omen w ould increase their c onsumption o f m eat i nstead o f relying o n p otatoes o r rye bread for their n utrition , a nd d eemed this to be a positive development since, he reasoned, it w ould lessen the likelihood o f a serious famine.
