even higher thought when the dele
gates to the sixty-second annual con-
vention of the American Association
for the Advancement of Science got
down to actual work.
Every one of these meetings is fea-
tured by some paper of exceptional
value to those attending and, since
these leaders in their lines have come
to Minneapolis for the purpose of ex-
changing ideas and getting, each from
the other, the best results of research
work they have done during the last
year. all the meetings are prolific Of
much that is of interest.
Calling attention to the recent cry
Of back to the farm" former Presi-
dent Folwell Of the University of Min
nesota told the members of the econo-
mic section that there was nothing at
tractive about farming to make far

or to drive urbanites to the simple
life" He said in part:
LAS a matter of fact, farming is
not paying business. In a good year
the average Northwestern farmer cul-
tivating quarter section, cannot ex-
pect an output of more than $500.
The average farm value of Mime
sofa crops, as shown by the twelfth
census, was $1,149. If $500 be allowed
for farm expenses and $500 for inter
est, there remains $500, that is So a

Figures Given On Waste.
He stated that in 1907, out of 10O,-
000,000,00O feet of timber cut, there
were more than 150,000,00O tons of
wastage. He then showed, from
series of experiments he had conduct
ed over number of years, that the
waste in the logging camps and the
mills could be utilized. He showed

c. L. Alsberg read a paper to the
chemists on the "Mechanisms of Cell
Activity"
The Progress of Food Chemistry"
was the title of paper read to the
chemists by H. e. Barnard, Indiana's
chemist and food commissioner. His
paper dealt with the progress made
since the passage of the national pure
food law.
Differences of opinion existing be-
tween the Minnesota and Wisconsin
geological schools concerning the
question of what rocks the term
'archean" embraces, were given ex-
preston in the geology and geography
section.
The controversy which has existed
for years was brought out by a paper
read by Carl Zapffe of Brainerd,
Mimi, Wisconsin school graduate,
who maintained that the rocks of the
Guyana iron ore district Of Minnesota
were of the same age as the Mesabi
range rocks. Prof. c. X. Leith, also
a Wisconsin man, conceded with
Zapffe In his contention.
N. H. Winchell, formerly Of the
University of Minnesota, insisted that
the Guyana rocks were of the same
age and character as the Vermilion
range rocks, but not the same as the
Mesabi. The same stand was taken
by C. w. Hall, professor of geology
at the University of Minnesota, who
presided over the meeting.
Green Sands Origin Treated.
At the morning session, Mr.. Winch

years, gave a paper on "The Origin of
Certain Green Sands in Minnesota"
