The Timber Trees of Ohio and their Eco- 

 nomic Uses: William R. Lazenby, Ohio 

 State University, Columbus. 

 A scientifically classified list of all the 

 timber trees of Ohio with notes on their 

 distribution and abundance. The princi- 

 pal demands or present economic uses of 

 wood are classified under fifteen different 

 heads. Among these are building material, 

 fencing, railroad cross-ties, poles for elec- 

 tric wires, transportation vehicles, cabinet 

 ware, agricultural implements, household 

 utensils, packages, paper, walks and roads, 

 chemical industries, mining purposes, fuel 

 and charcoal, miscellaneous uses. 



The amount and kind of timber for each 

 of the above uses are briefly discussed and 

 a list of woods used for minor but specific 

 purposes is appended. 



The Importance of Cooperation between the 

 Federal Census Office and the State Sta- 

 tistical Offices: Caeboll D. Wright, 

 Commissioner of Labor, Washington. 

 (Published in 'Report on Manufactures,' 

 U. S. Twelfth Census, Pt. I., pp. xl.-xlv.). 

 The law creating the permanent Census 

 Office provides that in 1905 and every tenth 

 year thereafter there shall be a collection 

 of the statistics of manufactures ; this is in 

 addition to the regular decennial census as 

 usually taken. The various State offices 

 are constantly engaged in collecting data 

 relative to manufactures ; hence it becomes 

 very necessary that duplication should be 

 avoided wherever possible, and that the ex- 

 pense involved in the work of State and 

 Federal governments should be either 

 shared by them or, so far as possible, 

 avoided entirely on the part of one or the 

 other. Probably there is not a State in the 

 Union that does not collect statistics rela- 

 tive to some of the subjects enumerated in 

 the law establishing the permanent Census 

 Office, and, specifically, there is a great 

 chain of State statistical offices, known as 

 such, having duties similar to those pre- 

 scribed for the permanent Census Office. 

 Thus a mass of information is published 

 each year, and especially every ten years, 

 so great that students and statesmen find it 

 difficult to study the details sufficiently to 

 enable them correctly to interpret results. 

 The fact that the results are open to 

 criticism is perhaps the smallest matter, 

 but certainly all data should be published 

 in as correct a form as possible and properly 

 interpreted and systematically and conven- 

 iently presented for public use. This de- 

 sirable result can be assured only by avoid- 

 ing the duplication of work, by systema- 

 tizing the methods under which statistics 

 are gathered, and by a imiform codification 

 of the results, to accomplish which desired 

 end it is absolutely essential that there
