Terpinenol, CijHjgO, is found in the oils of marjoram, cardamoms, cypress, and nutmeg, as well as in several others to a small extent. It has the following constitution —... 

To Jeff Paradis of CSU—Sacramento, I am thankful for his efforts in creating his activities manual, which complements this textbook so well. For developing the Conceptual Chemistry Laboratory Manual, I am forever grateful to Donna Gibson of Chabot College. For developing the Conceptual Chemistry Test Bank, I am deeply indebted to Bill Centobene of Cypress College as well as Dan Stasko of the University of Southern Maine. 

Cotton seeds are most popular as cores because the surface of the grain is downy so that it holds the composition very well. Rice chaff is also popularly used for smaller class shells. For larger shells seeds of Japanese cypress are used in mountainous districts and pieces of cork j are also used for the largest shells. In any case core material must be roughly spherical, must hold the composition well, and should not allow the fire to remain in it after the explosion and if possible it should be ultimately biologically degradable. 

For all cases more than 6 long, racks are moA con-vienent for drying them. These are made of Arips of H X 2 cypress or other light wood, suitable for supporting them. The longer the cases, the farther apart the Arips should be. AVhen fflled with cases they should be moved to a well ventilated room or covered platform. If placed in the sun they will be badly warped wben dry. (Fig, 3) Center and end Arips are x 3. ... 

Fig.22 shows an experiment of creating fire by friction using wooden objects. The mortar and pestle are made of well dried wood, the mortar is of Japanese cypress and the pestle of red lauan which is harder... 

Several species of Seiridium, including S. cardinale, S. cupressi and S. unicorne, are associated with the canker diseases of cypress, Cupressus sempervirens. The phytotoxic metabolites include the butenolides seiridin (8.61) and isoseiridin (8.62) and their 7 -hydroxy relatives as well as the sesquiterpenes seiricardine A (8.63) and B (8.64). Solutions of these sesquiterpenes when applied to leaves produce chlorosis, browning and death of the leaves. 

Soils. The peat is usually woody, dark brown, moderately well decomposed, and strongly acid. It contains buried logs and stumps, and has been built up on level sandy plains from a succession of two or three different forests dominated by cypress or white cedar and by mixtures with gum and red maple.
