but here again the moisture of our cHmate is enough to render 

 this Douglas safe here in regard to both extremes of temperature. 

 The reason why A. concolor and the blue Douglas stand drought 

 is to be found in the spreading nature of their roots, which can 

 seek out water in any crevice. To the same cause M. Jolyet 

 attributes the fact that Robinia, which generally wants depth in 

 the soil, stood the drought so remarkably well. Lawson's 

 cypress stood it fairly ; the Nordmann fir and the Fi?n4s excelsa 

 did well ; but the Weymouth not very well. 



V. M. Salvador writes at length on exotics and other trees to 

 be met with in the gardens of the Riviera, and considers which 

 of them might advantageously be tried in the Alpes Maritimes 

 under forest conditions. One may pick out a few of them which 

 might, perhaps, judging from what M. Salvador says, do fairly 

 well with us if placed in as bright and warm situations as we 

 can give them. The intensity of the light is the point which, it 

 seems to me, must be of so much importance with species coming 

 from almost anywhere out of England. Cupressus sempervirens 

 is a possible species ; it is hardy, and its wood is very valuable. 

 Cupressus toriilosa, a Himalayan species growing at 9000 feet in 

 its own home, has a very valuable wood, of a pink colour, but 

 needs good soils, and is not very hardy. Cedrus atlantica will 

 grow above 4000 feet in the Alpes Maritimes ; it will grow on dry, 

 oolitic soils, is hardy, and has a very valuable wood. Cedrus 

 deodara is somewhat less hardy. M. Salvador considers it 

 needs good soil. Like other Himalayan species, says M. 

 Salvador, it fears winter frost somewhat, but it seems to stand 

 it pretty well in England, and in its own habitat it has plenty of 

 it. I should like to say that since its wood, in its own home, 

 has such an absolutely superlative value, and since we know the 

 tree will at least grow here, and the wood even retains its 

 characteristic aromatic smell, it is at least probable that if grown 

 with care as to situation the deodar may turn out to be valuable. 

 It is said to have had its trial in England, but has it been tried 

 in real forest conditions ? I doubt it. I believe it should be 

 planted in woods in small groups amongst other trees (as beech), 

 and mixed with Pinus excelsa {the tree of all others with which it 

 grows so well in the Himalayas), on a warm, bright aspect, on a 

 decent soil, and, in order to put it in as natural conditions as 

 possible, on a slope. M. Salvador mentions many other species, 

 and of these Pinus halepensis and P. pinaster will grow to very
