cultivated only on a small scale in Germany. 

 The Pinus jeffreyi with white bloom covered 

 yearling shoots, buds without resin and light, 

 reddish brown scales with dark tips. Leaves 

 of a whitish green shade, in robust specimens 

 turned somewhat towards the shoot, and about 

 23 centimetres in length. The Pinus ponderosa, 

 with cylindrical buds terminating abruptly in a 

 short tip, close joining scales rather brown with 

 whitish tips, young shoots of a brilliant browny 

 green, and no bloom. The needles stand at right 

 angles from the shoot, colour dark green and of 

 the same length as the preceding species, Pinus 

 scopulorum. Shoots slightly bloom covered, 

 needles shorter than in 47 and 48. Buds 

 brown with whitish scale edges. 



Experiments are much fewer than formerly 

 chiefly because of the susceptibility of the seed- 

 lings to the Lophoderntium pinastri (Leaf- 

 shedding fungus). Schwappach, in his report, 

 says, besides, that the plants which at first de- 

 veloped pretty well, for some inexplicable reason 

 gradually withered and died later on. The timber 

 is equal to that of the indigenous product (the 

 name "ponderosa" is merely to show that the 

 wood is heavier than the Weymouth pine), so 

 that its production is unnecessary, even if it does 

 attain (after several hundred years) gigantic sizes 

 in West America.
