UNIVERSITY EXTENSION WORK IN FORESTRY 39 



membership of ten thousand and that the 14,000,000 acres of 

 land better suited to forestry than to agriculture are gradually 

 becoming busy at their one best job. 



New York and other states need men for this work. Men 

 who are up on the best modern forestry thought who are as 

 versatile as possible, endowed with vision and enthusiasm and 

 who will not be sunk by any brand of pessimism afloat. 



The annual convention of the Iowa Forestry and Conservation 

 Association was held in Ames February 2, 1916. The principal 

 topics for discussion were: 



The Proposed National Park for Iowa; 



The Conservation of the Iowa Lakes; 



County and State Parks and Forests; 



The Conservation of the Beauty Spots of the State. 

 The movement for the establishment of a National Park in 

 northeastern Iowa, the Switzerland of the State, as Senator W. 

 S. Kenyon has called it, was given hearty support. 



The Forestry Section of the Iowa Experiment Station issued 

 two bulletins written by G. B. MacDonald during the last year. 

 The two publications give the results of a very comprehensive 

 study of the preservative treatment of farm timber and the 

 renewal of windbreaks. The Experiment Station has undertaken 

 the reforestation of the sandy lands adjacent to the Mississippi 

 River in Allamakee County. Eight species of conifers are being 

 tried out in plantations. In the same region a large amount of 

 cottonwood is planted in the overflowed island lands. Cotton- 

 wood makes sawlogs in from twenty-five to thirty years. 



Carolina poplars put out on the College farm at Ames in the 

 spring of 1910 have yielded fenceposts in five years. Five hun- 

 dred and forty posts with a diameter of 3~y 2 inches and 720 posts 

 with a diameter from 2y 2 -3y 2 inches were produced on one acre. 

 If given a good creosote treatment costing from 10-20 cents 

 apiece, the posts will last from 20-25 years.
