Beat development in valley of Flat-

Soil and climate, and characteristics oi' 



Indifferent to imperfect drainage and flooding, but capable of 

 rapid growth on \vell-drained. moist, sandy soils, and hardy 

 as far north as latitude:;!! and 4u . and 'even on Western 

 prairies. Positively light-needing. To lie recommended for 

 extensive planting in favorable situations, where even, supe- 

 rior lumber may be expected. 



North of United States boundary, found on mnist uplands; 

 south in United States, in cold, wet swamps: hut probably of 

 more value when grown on deep, moist, well-drained soils, in 

 cool situations. 



Rapid and persistent grower; light-needing. Deserves attention 

 in Northern forestry, but only in mixed ^rnwllis. 



An important tree as a \Yeslrrn repjvsentalive of the I 

 species, occupying dry slopes in dry climate. 



VI. CYPRESS FAMILY. Under this head may well be grouped the .junipers and so-called cedars, to 'which c;tn 

 be added the California redwoods. Characterized mostly by the shingle-like arrangement of their small, scaly 

 leaves, the small, roundish fruit (a cone, or berry-like), and by the usually upright habit of the branches and scanty 

 fall of leaven. 



Their great endurance of shade makes them valuable adjuncts to forestry; otherwise of only secondary impor- 

 tance. Of the many species contained in seven genera, but fourteen are found in the United States. 



Wood light, soft, stift", not stroug, of line texture; sap and heartwood distinct, the former lighter, the latter a 

 dull, grayish brown, or red. The wood seasons rapidly, shrinks and checks lint little, and is very durable. Used 

 like soft piue, but owing to its great durability preferred for shingles, etc. Small si/es used for posts, ties, etc. 

 Cedars usually occur scattered, but they form in certain localities forests of considerable extent

34. YELLOW i:i Alt .. 



Soil and climate, and characteristics of growth. 



Prefers a mild climate; deep swamps, borders of streams, 

 ridges, hills; will thrive on a nither dry, loose soil. Kasiiy 

 propagated from seed and cuttings. Perhaps the most im 

 portant conifer for Southwestern praiiie planting, enduring 

 drought and partial shade. Tolerably rapid grower. 



Always in low, marshy, or wet ground, where it thrives well 

 and grows rapidly. Endures moist, upland soils, but with 

 slow growth. Very shade enduring; easy to propagate from 

 seed or cuttings. 



Small range; in Oregon along west- Commonly in low, moist, rich soil. Apparently hardy in the 

 ern coast from Coos Day, Oregon. ; Northeastern States and succeeds on deep, rich, upland soils 

 to Crescent City, Cal. and maintains itself in cla\ loam. 



(Cliamcecyparit nootkatensis 

 (Lamb.) Spach.)

Northwest coast region, from Mt. Like Arbor Vitffi. 

 Jefferson northward. Most com 

 mon on the seacoast north of i 

 United States boundary. 



Northeastern States and north- 

 ward. 



Will grow well in any soil not too stiff; often forming dense. 

 pure growths in vn't, boggy swamps, liapid grower; easily 

 propagated; desirable for undergrowth and to lill out places 

 where other trees fail to come. 



Northwestern coast and from Hum - Like the above species, on Pacific coast, 

 boldt, Cal., to British Columbia. 

 Best development north of 

 Seattle.
