OF ORNAMENTAL TREES. 53 



neath; about one inch long. Cones about 

 four inches long, and two broad, borne on 

 the ends of the branches, with many sharp, 

 linear bracteas at the base; ovate oblong. 

 Douglass's spruce. Native of the states on 

 the Pacific. Grows to one hundred and fifty 

 feet high, and is represented to be one of 

 the most beautiful of the tribe. The finest 

 specimen I have seen in the neighborhood of 

 Philadelphia is about five feet high, very 

 vigorous and hardy. This is on a sandy, 

 j^et moist hill, with a south aspect. On a 

 cold aspect, in a stiff loam, they do not suc- 

 ceed well. Most of the plants in the nurse- 

 ries are raised from cuttings, which make 

 fine plants ; but many are now raised from 

 seed obtained from their native places of 

 growth. These should be sown as soon as 

 received' in pans of sandy loam, the seeds 

 very little covered; and if they can be 

 placed in the soil separately, with their 

 sharpest ends downwards, it would be to 

 their advantage. Sometimes the seeds will 

 remain a year in the soil before germinating.
