TREES BEST ADAPTED FOB VARIOUS SOILS. 



planted, grow freely enough and wear a healthy appearance. 

 Oak and ash do fairly well, but they rarely attain to a large 

 size or produce first-class timber. Rhododendrons almost 

 revel in this soil, and some of the largest and healthiest are 

 growing with their roots in close contact with the coal and 

 ironstone. 



Concluding Remarks. In conclusion it may be pointed 

 out that it is only by a careful selection of soil that we may 

 expect tree planting to be successful, and I have no hesitation 

 in saying that many failures can be clearly traced to errors 

 in judgment in the selection of trees for planting on 

 particular soils. The subject is a wide and complicated one, 

 and it must be admitted that very perplexing diversities 

 occur with the same kinds of trees on what, to all appearance 

 is the same class of soil. There are, of course, other 

 considerations beyond the soil itself which must be taken 

 into account, such as aspect, elevation, and whether the 

 ground is inland or on the coast. 



With reference to some of the newer conifers it must be 

 admitted that soil and situation have a wonderful influence 

 on their successful culture, and this applies in particular to 

 such kinds as are not perfectly hardy and liable to injury by 

 unseasonable frost. The too common practice of selecting 

 warm and sheltered spots for such is, in the main, to be 

 condemned. 



It may be said that Abies cephalonica and A. Pinsapo are 

 not worth growing, and in many places they are not, but 

 when planted on limestone or chalk they are highly 

 ornamental. 



The same holds good with Tsuga Mertensiana, Picea 

 sitchensis, and P. excelsa, which are rarely seen in good form 

 except on soil of a peaty description. 



Everyone at all interested in trees and shrubs knows that 

 there are certain kinds which in a state of Nature are only 

 found growing in a peaty soil, mixed it may be more or less 

 with sand, and any attempt to cultivate them in other soils 

 is productive of very unsatisfactory results. 



Who would ever think of planting the so-called Americas, 

 or peat plants, Cape Heaths, &c., amongst gravel or chalk,
