94 Canadian Forestry Journal. 



The bulletin is the report of a preliminary examination of the 

 Luquillo Forest Reserve, situated at the east end of the island of 

 Porto Rico, and set aside in January, 1903. The reserve is sup- 

 posed to contain 65,950 acres, of which only about 20,000 acres 

 is Federal forest land. The highest mountains on the island are 

 Vvithin the boundaries of the reserve, which is evidently intended 

 primarily to protect the water supply for the surrounding- districts. 

 FVom a general description of the forest 10,000 acres are estimat- 

 ed as timber lands, said to contain 25,000,000 board feet, the re- 

 maining 10,000 acres consisting of mountain peaks and palm 

 lands. Very little lumbering so far has been done in the district, 

 nijost of the wood used in the island being pine imported from the 

 United States. The principal forest tree of economic importance 

 seems to be the Tabanuco (Dacryodes hexandra, Griesefb), the 

 wood of which is somewhat similar to that of yellow poplar or 

 tulip tree of the Eastern States, 



The report enumerates the general industries of the district, 

 discusses transportation facilities and necessity for good roads, 

 concluding with recommendations for the management of the 

 reserve. 



Progress Report on the Strength of Structural Timber. By

This is a partial report of the results of some of the tests at 

 present being carried on by the Bureau to determine the mechani- 

 cal properties of various commercial timbers of the United States. 

 Another publication will be brought out shortly giving detailed 

 descriptions of methods used in making the tests, with a more 

 complete report of all the results obtained. The tests have been 

 limited to : ( i ) Species that promise to be on the market for an 

 indefinite time: (2) Actual market products: and (3) Such 

 purely scientific work as forms the basis for correct methods of 

 test. The species undergoing investigation are : The 

 Pacific Coast Red Fir (Pseudotsuga taxifolia) ; Wes- 

 tern Hemlock (Tsuga heterophylla) ; Red Gum (Liquidambur 

 styraciflua) ; and Loblolly Pine (Pinus taeda). The loblolly 

 pine and Pacific Coast timbers are tested in the form of large sticks. 

 such as bridge stringers. These are subjected to the various
