preponderance of the material deals with herbicides as they are used in vegetation management in a diver sity of situations and environments," Ν AS says. But the academy points out that data abound on that topic while they are scarce on ecological results of repeated or heavy use.
LBJ's education proposal already running into trouble President Johnson's proposals for fed eral aid to higher education, which he outlined in a special message to Con gress last week, have already run into a little trouble. Surprisingly, the sour comments emanating from Republi can members of the House Education Committee were aimed at the Presi dent's proposal to cut spending for construction of college buildings. In his message, President Johnson said, "We must carefully set our pri orities. To meet our urgent needs within a stringent overall budget, sev eral programs must be reduced or de ferred. We can reduce expenditures on construction of facilities and the purchase of equipment. But, many of our urgent educational programs which directly affect the young people of America cannot be deferred." The President proposes to cut spending for the college construction grant program by $75 million: $225 million in fiscal 1969 compared with $300 million in 1968. As hearings opened on the propos als, Rep. Albert Quie (R.-Minn.), sec ond-ranking Republican on the House Education Committee, challenged U.S. Commissioner of Education Harold Howe on the cuts in con struction funds. Pointing to the steady increase in college enrollments, Rep. Quie asked, "At the rate of re duction that the President has made in funds for college facilities, what is he going to provide for professors and students to work in?" Commissioner Howe's answer: "You have to recognize that the Presi dent took the position that this is a tight budget year and calls for priori ties. It is a clear response to the call of Congress for this kind of action." As hearings proceed, it probably will become apparent that voluntary cuts in spending will not be restored. Major points in the President's plans for higher education include: • Strengthening the guaranteed stu dent loan program by meeting the ad ministrative costs of the banks who make the loans. • Unification and simplification of student aid programs so colleges have flexibility to tailor aid plans to the needs of individual students.
• Several modest new programs of tutoring, counseling, and the like. The President also wants Congress to approve a Networks for Knowledge Program under which schools will pool faculties, equipment, and facili ties; an increase in federal payments to graduate schools; a new program to strengthen "those graduate schools with a clear potential for higher qual ity"; and an increase in governmentsponsored research activity in univer sities. For elementary and secondary schools President Johnson proposes modest increases in current aid pro grams and several new ones. The actual cost of the President's proposals is not clear as of now. Many of the programs have no price tags at all. However, the 1969 bud get forecasts educational spending of $4.7 billion, an increase of $158 mil lion over the present level.
Goodyear develops adhesive for reinforced polyester Goodyear Chemical has developed an adhesive system designed especially for fastening glass-fiber-reinforced pol yester (FRP) to itself and to metal. At the Society of the Plastics Indus try meeting in Washington, D.C., last week, Goodyear's Samuel M. Berkowitz said the new adhesive, a modified polyurethane, can reduce by more than 20% the cost of fabricating FRP components for two reasons: expen sive surface preparation steps such as shot blasting are eliminated, and the system lends itself to mechanized dis pensing and joining. The system is already being used in significant production applications. For example, International Harvester is using it on a production line that assembles 35 FRP truck cabs per day, and Molded Fiber Glass Co. is using it in some boat assembly applications. Volume applications in passenger au tos, for hood and rear-deck assembly, are imminent, Mr. Berkowitz says. Adhesives are used almost exclu sively for joining FRP components because mechanical fasteners such as bolts or rivets create highly localized stresses. The two types of adhesives usually used for FRP are polyesters and epoxies. Polyesters are favored in volume applications because of lower prices. But in addition to the need for extensive surface preparation and the unsuitability for mechanized bonding procedures, both these types of adhesives have other drawbacks, such as being brittle and having a ten dency to "bond burn." Bond burn oc curs when the adhesive curing reac tion generates enough heat to distort
the surface of the polyester substrate. The new Goodyear adhesive cures below 150° F. and thus does not bond burn. In addition, the bond is highly elastomeric and can absorb shocks and stresses. The Goodyear adhesive is a twocomponent system consisting of the urethane base adhesive and three dif ferent proprietary curing agents. By selecting the appropriate curing agents the cure time required to achieve 100p.s.i. bond strength can be varied from almost instantaneous (using heat) to about 10 minutes at room temperature. In addition, either nonsag or selfleveling characteristics can be ob tained. A completely mechanized dis pensing system using heated position ing fixtures can produce a bonded part in less than two minutes, com pared with about 15 minutes using other methods, says Mr. Berkowitz. Base cost of the new adhesive is about the same as that of epoxies. But cost studies show that elimination of the shot blasting step and the rapid cycle times result in lower costs per bond than with conventional adhe sives.
CUNY plans ghetto-oriented community college in Brooklyn The City University of New York (CUNY) and the city's board of higher education have designated the sprawling ghetto neighborhood of Brooklyn's Bedford-Stuyvesant as the location for an experimental two-year community college. The proposed school will be CUNY's seventh com munity college but the first planned for the underprivileged high school graduates of an area that could have
