to what courses should be recommended nor to indicate the year in which we believe a certain course should he given, although admittedly these are important problems. What I am trying to suggest is this. Many students encounter schedule difficulties in the later years of their study of chemistry for the simple reason that, somewhere back in the line, they failed to take the right course a t the proper time. Indeed, altogether too many students emerge from the college, and even from the graduate school, without properly balanced courses. It is my contention that most of such difficulties could he avoided if the departments of chemistry should see to i t that adequate information and intelligent guidance are available for all who wish to specialize in chemistry. Such a guidance program presupposes that the department of chemistry has studied the problem as it exists in the school concerned, has made contact with and secured the cooperation of the departments which must give the related and supporting courses, has checked the schedule of the college to see that conflicts are avoided, and finally has provided the printed matter, information, and personnel to carry out its program.
A New Container Material. The commercial development of a new process by which asphalted fiber is converted on a standard paper machine directly t o a highly waterproof paper board offers many interesting possibilities in the packaging of materials for shipping and distribution. As compared with the conventional type asphalt-saturated papers and boards, the new product is of further economic interest, as it can be made from lower cost raw materials due t o the elimination of the rag stock normally required t o facilitate asphalt saturation. T o permit printing as well as marking, the new board is usually made up with "liners" or facings of kraft paper. The body of this board may be embossed when desired as a further decorative effect. The new material will maintain adequate strength not only through a wide range of atmospheric conditions from wet refrigeration to a steam-saturated air, but also under the severe test of submergence in water for a twenty-four-hour period. Fabrication and sealinn methods have been developed for the conversion of this board t o containers of several types which meet demands previously considered beyond the field of either solid fiber or corrugated stock packaging. An interesting development is a ventilated container for f r u i t and produce. If necessary the package may be iced directly without risk of weakening the walls and consequent crushing of the contents. Special types of reinforcing permit the manufacture of this package in rectangular shapes, thus affording maximum economy in space for shipping and storage as well as in icing charges. One element of this reinforcing provides a tray for one layer of fruit a t the tap of the box, and thus permits uniform display until the contents are completely sold. Another of these containers meets the exacting specifications for the shipping and handling of dynamite. The folded construction and special sealing where lap joints are necessary makes this container much tighter than any wood construction available a t comparable cost.-Ind. Bull., Artltur D.
