THE RKDWOOD. 



or liumus, which enriches the soil, keeps it moist, and makes growth 

 more rapid. As the crowns grow up, in the struggle for light and 

 room most of the weak or intolerant trees die off. The Hemlocks 

 survive and parti}' keep up, because tiwj can stand a good deal of 

 shade, but the Willows and Alders become restricted to the openings. 

 It happens, therefore, that wherever the suckering has been thick 

 enough at first. Redwood finally dominates all the other species and 

 occupies most of the ground. 



THE TRACT AT TRINIDAD. 



A fourth tract, which showed more typical conditions and the kind 

 of situation characteristic of most of the Redwood belt, was found at 

 Trinidad. The topograph}' there is a broad coastal terrace, rising 

 gently from the sea cliff's and cut b}" the canyons of several small 

 streams. About 2 miles inland the terrace rises to an altitude of 500 

 feet, and the soil becomes coarse and poor. The tract of second- 

 growth Redwood stands on a plateau-like divide between the two 

 gulches. The age of the stand is 26 years. 



THE VALUATION SURVEYS. 



Valuation surveys were run at Crescent City, Areata, and Trinidad. 

 The results are given in the following table:
