layering them as above they are very easily managed, and would grow 

 on without injury for a considerable time, if they cannot be removed. 

 Be assured, you will get much better plants, and at less than half the 

 trouble, by this plan. 



Planting : — Large growing sorts, as the Victoria, Queen, Sir Harry, 

 &c., should have the rows three feet apart, and the plants two feet 

 from plant to plant ; but for common produce eighteen inches will be 

 sufficient. Short-topped kinds may be two feet six inches apart, row 

 from row, and rather closer in the row ; water occasionally, pinch off 

 all runners as they appear through the autumn : these will bear well 

 the following season. The crop will last in perfection from three to six 

 or seven years, according to the nature of the soil and management, 

 which I will notice hereafter.

 PINUS LAMBERTIANA: 



THE GIGANTIC OK LAMBERT's PINE. 



We again resume our notice of this important family of plants by 

 giving a wood engraving of Lambert's Pine, taken from a tree growing 

 in the Pinetum at Nuneham Park, near Oxford. 



Pinus Lambertiana belongs to the Strobus or Weymouth Pine 

 section of the five-leaved Pinuses, and which contains, besides the 

 subject of our present notice, P. excelsa, from the Himalayas, P. 

 ayacahuite, monticola, and the Weymouth Pine, from North America. 

 They are noticeable for having silvery grey leaves, rather drooping, and 

 for their rapidity of growth and large size. 



This noble Pine was discovered by Douglas in 1825, when at the 

 head waters of the Multnoman river. This enterprising traveller again 

 met with it in 1826, " beyond a range of mountains running in a 

 south-west direction fi'om the Rocky Mountains towards the sea, and 

 terminating at the Cape Orford of Vancouver. It grows sparingly upon 

 low hills and undulating country east of the range of mountains just 

 mentioned, where the soil consists entirely of pure sand, and in appear- 

 ance is incapable of supporting vegetation ; here it attains its greatest 

 size, and perfects its fruit in great abundance." Douglas further states 

 that P. Lambertiana does not form dense forests, like most of the other 

 kinds which clothe the face of North America ; but, like P. resinosa, 

 which grows among them, they are scattered singly over the plains. 

 Its geographical limits appear to be from 40° to 4o° N. lat. 



Lambert's Pine attains the largest dimensions of any of the true Pines. 

 According to Douglas, it grows from 160 feet to upwards of 200 feet in 

 height, varying from 20 feet to 60 feet in circumference. One that 

 he measured which had been blown down by the wind, was 215 feet 

 in length ; its circumference, at three feet from the ground, 57 feet 

 9 inches ; at 134 feet from the ground, 17 feet 5 inches ; and this was 

 not one of the largest trees he saw. The trunk is unusually straight, and
