by students, faculty, and others in
the community."
  He listed as outstanding accom-
plishments of the center: establish-
ment of an up-to-date, well-indexed
library of books, articles, and pam-
phlets on drugs, with library usage
by more than 800 persons; distribu-
tion of a pamphlet entitled Drugs and
You, which summarizes existing laws,
gives a brief account of several drugs,
and lists places where information
and help are available; provision of
staff members to lead classroom dis-
cussion and student-age drug special-
ists to "rap," sometimes by the hour,
"with people for whom library infor-
mation is not enough." (Specialists
have some training in pharmacy, in
small group work, in informal coun-
seling, and even in handling suicide
calls, Young pointed out); establish-
ment of "good working relationships"
with student groups concerned with
drug abuse and of means to help
high schools and elementary schools
where habits of drug use are estab-
lished.
   Young recommended to the com-
 mission that it ask for more federal
 funds for educational programs on
 drug abuse. He also recommended
 "serious and continued study of ex-
 isting laws on drugs, for it seems to
 me that many existing laws need to
 be more closely aligned with facts
 about drugs and with enlightened
 societal attitudes about mind-alter-
 ing substances."
 UW Entomologists Fight
 To Beat the Dutch
    The fight to save majestic elm trees
 on the campus is on in full-force with
 the UW departments of plant pathol-
 ogy, and entomology, and grounds
 crew cooperating in an attempt to
 stem the tide of Dutch elm disease.
    Objects of the battle are the 700
  stately elms, many over 100 years
  old, which make up the bulk of natu-
  ral campus beauty.
  This summer, 20 "prime" disease-
infected elms began receiving "shots"
-innoculations of a DuPont chemi-
cal Benlate-in a move which elm
disease experts here hope may prove
to be a break-through in the disease
control of early infected trees. The
chemical, a powder, is mixed with
water and injected into the tree's
new large vessels from two to three
inches apart around the tree's circum-
ference. The tree pulls the solution
into its system as part of its growing
process.
   "There is some evidence that Ben-
late in the powder form, applied to
soil around the tree, does prevent the
disease. However the 600 to 800
pounds per acre needed would never
be approved by the Environmental
Protection Agency," according to a
pioneer in Dutch elm disease re-
search, Prof. Eugene B. Smalley,
plant pathology department.
   "Although we have no hard evi-
 dence that the injection treatment
 will work, we will have some data
 by next spring. Now we can only
 watch and wait," Prof. Smalley said.
   In the meantime, besides repeating
 the Benlate injections in infected trees
 every 10 days, ground crew person-
 nel conduct daily checks for signs of
 infected elms on campus.
   "When a tree starts to 'flag', 'With
 the leaves turning a bright yellow,
 we take a sample over to the state
 Department of Agriculture for analy-
 sis. This year so far, of the 64 sam-
 ples taken, over 90 per cent have
 come back positive, meaning the trees
 are infected," Bud Crawmer, grounds
 department foreman, stated.
    UW researchers assisted in con-
 trolled experiments of injected Ben-
 late during the summer in the Mil-
 waukee suburb of River Hills. Benlate
 was also sprayed on elms as a mist
 in the city of Milwaukee. "Naturally,
 we are watching these experiments
 closely," Smalley added.
    Since Dutch elm disease was first
  spotted on campus in 1959, the UW
has sprayed s e 1 e c ted campus elms
annually to control the disease car-
riers, the European and native bark
beetles. Methoxychlor, a degradable
insecticide, replaced the now-banned
DDT chemical in 1961.
   "Methoxychlor is quite potent for
30 days after it is applied and lasts
for about 60 days if we're lucky,",
Prof. Dale M. Norris of the entomol-
ogy department said. "Spraying is
often difficult, however, since it must
be applied in the spring and there are
few days when it is not too windy."
   Prof. Norris is conducting research
 attempting to discover attractants and
 repellents to the bark beetle. "If we
 can determine specific chemical
 make-up in the elms which attract
 the beetles, we can begin working
 on repellents," Norris said.
   Beginning in 1957, when Dutch
 elm disease was discovered in Wis-
 consin, UW researchers have been
 at work collecting elm species from
 all over the world to select elms re-
 sistant to the disease. Twenty acres
 devoted to the development of these
 elms at the UW's agricultural re-
 search farm at Arlington have begun
 to bear fruit.
   The first plantings of certain im-
 mune elm hybrids selected in early
 studies were planted on the west end
 of campus three years ago. The trees,
 five years old when planted, will re-
 quire from 35 to 40 years to reach
 maturity, according to Prof. Smalley.
 Losses of prime elms on campus have
 averaged around 70 per year in the
 past few years.
    "We are hopeful the Benlate ex-
 periment will turn the tide," Smalley
 said, "just marginally hopeful."
 Land Chosen As Site
 Of UW Golf Courses
    Options have been taken on 580
  acres of farmland near Madison
  which will ultimately provide the Uni-
  versity with two outstanding 18-hole
  golf courses and other outdoor facil-
