CONIFERS AND SOILS 217 



Clayey Soil 



For planting in stiff, clayey soils I have found 

 Cryptomeria japonica and its variety elegans, 

 Thuya plicata and T. occidentalis, to be by far 

 the most useful ; while where ironstone and coal 

 are present, nothing excels Cupressus Lawsoniana, 

 Jtmiperus communis, Larix europcea, Pinus Cembra, 

 and P. montana.
