Formerly known as 7huia Lobbit, is widely distributed 
over the North-Western parts of North America. In the 
valley of the Columbia river it attains a height of two hundred 
feet, Professor Sargent says, “sending up a mighty shaft 
free of branches for upwards of a hundred feet, from an 
enormously enlarged base tapering gradually until at twice 
the height of a man from the ground its diameter may not be 
more than a dozen feet. Beside these giants the other Arbor- 
vitzes of the world are but pigmies.” It is a most stately 
tree, and so thoroughly hardy that it may be planted with 
safety in the coldest and most exposed parts of the British 
Isles. It is also about the most rapid growing conifer we 
possess. As an instance, I had to move several in 1887: they 
were then fourteen feet high; in 1903 they are sixty-five feet 
in height, with a circumference of a hundred and sixty feet, 
thus making an annual growth of over three feet. It cones 
here very freely.
