Where there is any option, a site should be chosen in one of the following types of soil in the order of preference given: a) Wet marshy ground ; b) Clay, loamy soil, arable land, clayey soil, clayey soil or loam mixed with small quantities of sand; c) Clay and loam mixed with varying proportions of sand, gravel and stones; d) Damp and wet sand, peat. Dry sand, gravel chalk, limestone, granite and any very stony ground should be avoided, and also all locations where virgin rock is very close to the surface. A site should be chosen that is not naturally well-drained. A water-logged situation is not, however, essential, unless the soil is sand or gravel, as in general no advantage results from an increase in moisture content above about 15 to 20 percent. Care should be taken to avoid a site kept moist by water flowing over it (for example, the bed of a stream) as the beneficial salts may be entirely removed from the soil in such situations.
