The Forest Service has issued a bulletin announcing that the 

 supply of dogwood and persiinmon in the southern States is 

 nearly exhausted. These woods furnish, it is said, the entire 

 supply of bobbins, shuttles, and spindles used in the cotton and 

 woolen mills. Dogwood is said to be the only wood which 

 takes a high polish and wears perfectly smooth by friction under 

 water. Two large plants for the manufacture of bobbins and 

 shuttles have been erected in Oregon, where the dogwood forests 

 are the greatest in the world, the trees often reaching a height of 

 75 feet. Eastern manufacturers, however, are trying to find sat- 

 isfactory substitutes nearer home, the most promising of which 

 is probably the tupelo gum. 



The New York Tribune announces that visitors to California 

 will " have access to a third forest of giant redwoods when the 

 counties of Tulare and Fresno complete construction of twenty- 

 five miles of highway between Visalia and Redwood Canyon, in 

 the Kings River country, where there is a grove of over fifteen 

 thousand magnificent specimens of the Sequoia gigantea, many 

 of which are said to compare in size and beauty with the trees 

 of the Mariposa and Calaveras groups. It is probable that the 

 property, which is as yet untouched by lumbermen, will be recom- 

 mended to Congress for purchase as a national park. One tree 

 in the redwood grove, recently measured by a government ranger, 

 is no feet in circumference and is estimated to contain 800,000 

 feet of lumber. A claim is made that a fallen giant in the region 

 is the largest in the country. Located at an altitude, of less than 

 six thousand feet, the canyon would be accessible for a longer 

 period than the other giant groves in the state." 



The Plant World for June contains a paper on stomata by 

 Professor Francis E. Lloyd. The study upon which the article
