FORESTRY IN TEXAS 

 Much constructive 'work was accom- 

 plished at the recent annual meeting of the 

 Texas Forestry Association, at Houston. 

 The attendance was the largest in the his- 

 tory of the organization and prominent 

 conservationists and lumbermen were pres- 

 ent. Col. W. B. Greeley, chief of the 

 United States Forest Service, was the 

 guest of the association and the first 

 speaker. His address was devoted mainly 

 to the importance of reforesting the vast 

 areas of idle lands, formerly in timber and 

 now better adapted to the growing of tim- 

 ber than to any other purpose. This 

 problem, Col. Greeley said, applied partic- 

 ularly to Texas and the Southern states, 

 because "the future development of the 

 South demands an abundant supply of tim- 

 ber for the economic development of its 

 industries. * * * The slogan of the 

 country once was 'Back to the land.' Now 

 the cry from all over the United States is 

 'Back to the forest!'" 

 The policy of the association and its

DELAY CAUSES BLISTER RUST 



A delay of one year in destroying the wild 

 currants and gooseberries as a protection 

 against the blister rust will result in the 

 loss of at least 11 per cent of the tree* 

 in a young wihite-pine plantation at Nortil 

 Hudson, New York. 



This planting of white pine was made 

 for the purpose of producing another tim- 

 ber crop on an area previously denuded by 

 fire. Three-year-old trees were set out 

 in the s>pring of 1919, but the wild cur- 

 rant and gooseberry bushes on the tract 

 were not destroyed until 1920, a year after 

 the planting. The removal of the currant 

 and gooseberry bushes is necessary to save 

 pine trees from the blister rust, because 

 they are the only means by which this dis- 

 ease can spread. 



The pines in the plantation were ex- 

 amined in the fall of 1921 by agents of 

 the United States Department of Agr 

 culttre. As a result of the trees being e^ 

 posed for a single year to the bluister rn 

 on the currant and gooseberry bushes, it^ 

 was found that 86 trees showed infectio 

 originating in 1919; 197 were missing and 

 483 showed no sign of infection. Thus 

 15.10 per cent of the living trees or 11.20 

 per cent of all the trees set out on the plat 

 were infected by the blister rust in a sin- 

 gle year, and will succumb sooner or later. 

 If the bushes had been removed before the 

 pines were set out, this loss would have 

 been prevented. 



TREE PROTECTION INSTITUTE 



Connecticut is the first State to create 

 a Tree Protection Examining Board. This 

 board requires that no one shall practice 

 tree preservation without first passing 

 written and oral examination on insects, 

 tree diseases, tree surgery, tree life and 

 growth, and tree species. Upon success- 

 fully passing this e-xamirtation a State 

 Certificate is given. 



To further educate the workers, and cre- 

 ate an added interest in the care of trees, 

 institute meetings are held which aim to 

 bring all tree wardens, superintendents of 

 trees, park superintendents, and all lovers 

 of trees together to hear able addresses, 

 and to take part in the discussions. 



On Tuesday, February 21, such a irveet- 

 ing was held at the Connecticut .Agricul- 

 tural Experiment Stajtion, New Haven. 

 Dr. W. E. Britton, Chairman of the Board, 

 opened the institute. Dr. G. E. NichoJS, 

 of Yale, gave a very clear and comprehen- 

 sive talk, well illustrated, on "The Living 

 Tree." Prof. S. P. Hollister, of Con- 

 necticut Agricultural College, next talked 

 on various pruning methods, and spraying 

 programs.
