probably prove of great value and the same is true for similar areas in 

 New South Wales and possibly Victoria where the climate is sufficiently 

 warm and the rainfall a summer or all the year round one. The Chir 

 and Canary Island Pines may be regarded as supplementary to one another. 

 Temperature and soil being equally favorable the former succeeds where 

 a summer rain prevails, the other where it is a winter one. There are 

 places enjoying an all the year round rainfall where both grow well, but 

 the Himalayan Pine will thrive under more tropical conditions than the 

 species from the Canary Islands. The timber of both is equally good. 



At Macedon, near Melbourne, Pinus ponderosa Dougl. is next to 

 Insignis Pine the most valuable species and it is equally good round 

 Ballarat. It grows rapidly and regenerates freely and in these districts 

 its planting will be widely extended. Just which of the many forms it is 

 that does so well in these districts I w r as unable to determine but those 

 interested would be well advised to raise plants from their own home- 

 grown seeds. At Orange in New South Wales this Pine does w r ell and it 

 is probable that this will be found true for many other districts in this 

 state, among others the temperate regions of the Kosciusko range between 

 Tumut and Cooma. The form known as Benthamiana Lemm. succeeds 

 splendidly in Hobart but the var. Jeffreyi Vasey and others only do moder- 

 ately well. In New Zealand several hundreds of acres of P. ponderosa 

 Dougl. have been planted either as pure stands or mixed with the Laricio 

 Pine (P. ni$ra var. Poiretiana Schneid., but better-known as P. laricioYoxr.) 

 and the results in general are satisfactory. On the Canterbury Plain and 

 in Otago where the climate is drier than the average it does remarkably 

 well, and gives every promise of becoming a valuable tree for forest 

 planting. In rocky places P. ponderosa var. scopulorum Engelm. does 

 well in several places in the South Island. 



In South Africa, where the testing of the various species of Pinus is 

 being carried out on a larger scale and in a more thorough manner than 

 elsewhere in the antipodes, P. ponderosa Dougl. is being very carefully 

 studied. For the northern Transvaal where the elevation is considerable 

 (6000 feet and upwards) and the rainfall a summer one the varieties 

 arizonica Shaw and macrophylla Shaw (P. Engelmannii Carr.) give the 



best promise. 



The Austrian Pine (P. nigra Arn.) has been very extensively planted in 

 New Zealand, both pure and mixed with other trees, but except here and 

 there in the drier parts of the South Island it must be considered a failure. 

 In the Rotorua conservancy it is quite worthless. The growth is slow and 

 stunted and disease is prevalent. The Laricio Pine on the contrary 

 flourishes and with P. ponderosa Dougl. ranks after Insignis Pine as the 

 best variety for New Zealand. This Laricio or Corsican Pine has been 

 planted in quantity in both the North and South Islands and is nearly 

 everywhere a success though its rate of growth is only about half that of 

 Insignis Pine. At Hobart, Laricio does only moderately well but I should
