_Cupressus macrocarpa_ also has done fairly well: the growth certainly has not been rapid, but for all that the general appearance of the trees is the reverse of what one might expect from the unfavourable nature of the soil. The Indian Cedar (_Cedrus Deodara_) we have found to be peculiarly well suited for planting in clayey soils, the bright silvery tint that is so characteristic of this cedar when well grown being discernible in the clay-grown specimens. _Pinus austriaca_ has, in a few instances, done well, the foliage being ample and of the usual dark yew-green. Amongst shrubs the double-flowered gorse (_Ulex Europæus_, fl. pl.) has done best of any—indeed, it has grown and increased freely, and would seem to be quite as much at home as in its natural element—a dry, gravelly bank. These may be considered as the trees that have succeeded best in stiff, clayey soil. Few of the pine tribe did well, and this may also be said of the spruces, cypresses, yews, junipers, arbutus, dogwood, cotoneaster, hollies, and others planted. It is, of course, far from advisable to plant trees or shrubs in such unkindly soil without first adding other of better quality; but it is of great value to know that there are a few trees and shrubs that will thrive almost in defiance of the stubborn and unkindly nature of a stiff clay soil. (5) =Ironstone Soils.=—The particular class of soil to which I refer, and which in several districts occurs in plenty, is on the coal and ironstone formation, where the top soil is usually shallow, and the subsoil consists of a loose, yellowish rag that is largely impregnated with iron. In most places but a very small quantity of soil exists, and that is of the poorest description, varying in depth according to the lie of the measure. The Spanish Chestnut is one of the very best trees for this soil, growing with freedom, and producing a fair amount of good timber, while its appearance indicates perfect health.
