It is the California nuimeg tree (Tumion californicum) , also 

 known locally as torreya, fetid yew. stinking cedar, coast nutmeg, 

 and false nutmeg. It grows in the redwood belt in northwestern 



California, but grows also in a few other localities west of the 

 Sierra Nevada mountains in that state. It is an evergreen, with 

 leaves bearing some resemblance to those of hemlock, but larger, 

 and their tips are as sharp as cactus thorns and are liable to 

 injure anyone who carelessly approaches the branches. The fruit 

 looks like an olive in both shape and size. 



The wood is a little heavier than southern red cedar and has

that a market for it can be found in factories which make small 

 articles of furniture, or small musical instruments. The handsome 

 yellow woods of this country are scarce and this one might be 

 worked to advantage in a number of ways. 



The average size of the nutmeg tree is about twenty Inches in 

 diameter and fifty feet in height, but in the damp forests of Hum- 

 boldt county, California, heights of eighty feet and diameters of 

 four feet are met with. Trunks are smooth and of good shape 

 when trees grow in dense stands, but if they grow in open ground, 

 the poles are knotty and little clear wood can be had. 



No statistics of output can be quoted for this tree, because the 

 lumber has always gone to market under some other name, gen- 

 erally as yellow pine, but no great quantity of it has ever gone 

 to market. It is not very abundant, but considerable of it might 

 be had, if wanted. 



The Veneer Hat 



The veneer hat for men is said to be coming. Its shape is 

 similar to the helmet worn by our soldiers over the sea. Thin 

 sheets of wood are worked into three-ply panels, using water-proof 

 glue. The panel is then steamed and pressed in the desired shape. 

 Sun and rain should have little effect on it. Such hats might be- 

 come popular with persons who work out of doors, or with those 

 who spend vacations in the woods. The sheets of veneer can 

 be cut so thin that the w^eight of the hat will be very small. Wood 

 is a non-conductor of heat, and veneer hats may find favor during 

 hot weather. However, wooden hats are not new. Patterns were 

 produced on the lathe fifty yeais ago, but they were not veneer 

 and were heavy. 



Resistance of Animal Glues to Moist Air 



That there is a choice relation betw^een the viscosity, and 

 therefoie the grade of animal glues and their moisture resistance 

 is strongly indicated by recent tests made at the Forest Products 

 Laboratory. 



Test specimens were made of two pieces of one-eighth-inch birch 

 veneer glued together with the grain in opposite directions so as 

 to give 1 square inch of glued joint surface. The specimens were 

 suspended in a humidity chamber with a 1 -pound weight hung 

 on each, and the time required for failure of the glue joint was 

 noted. The first two tests were made at 98 per cent humidity. 

 In the third test, the specimens were kept at 90 per cent humidity 

 for 120 hours, after which the humidity was raised to 98 per cent. 

 No failure occurred at 90 per cent. The temperature used in 

 each test was about 80° F. 



Resistance of Glues of Different Viscosity to Moist Air 



(a) Vegetable glue. 



(b) After raising humidity to 98 per cent. 



The results indicate that the moisture resistance of animal glues 

 is proportional to the viscosity, jelly strength, and grade.
