StSl lew lllOuSnlS. states lew facts
that are already self-apparent, and
drops the subject. | suspect there is
point hidden here somewhere, but l
don't quite grasp it.
lie next attacks the number of times
the air is changed in the rooms in an
hour. While believe and know every
figure of the measurement of air in my
report TO be absolutely true at the
time they were taken, and that
they show by the usual method of
such computations the air to be changed
eight times per hour, | wished to be
very conservative ana divided it by two
Tor the following reasons:
LIST. There was necessarily from ten
minutes TO half an hour between the
times the two urrents-ingoiIg and
outgoing were measured.
2nd. In spite of all precautions TO
the contrary. doors would he opened
quite frequently during our eXamin-
alton,
3rd. | wished to allow for creyices
around doors aud windows.
These reasons each have more or
less influence upon the current of air
passing through a loom. You, of
course, understand that the measure
ment of air passing through room is
far from being absolutely correct. Not
one cubic foot of air can come into
room unless corresponding cubic foot
goes out, and vice versa. unless the
room is Theoretically sealed.
These measurements are for the pur-
pose of aScertaining whether there is
any current or not, and approXimaJing
as to its volume and velocity.
My critic, not being satisfied with my
conservatism, carries me ont to the
Tilden school, where, according to his
figures, he finds ''whirlwind."
Let me analyze this ''whirlwind."
lie says, according to my report at
Tlden school, the air changes twenty
three times per hour: l shall ask him
10 allow me to call it twenty, for the
every three minutes. The room is
thirtyfour feet long-whaU Il wonderful
velocity that current of air has got to
attain to travel thirty-four feet in
three minuteS.-I wonder If it ever
occurred to him that one can pace off
800 feet in three minutes. walking very
lciSurely- and not Use stills either.
The reference to the temperature
chart attached to my report l will pay
no attention to. as the principal state
meHt made IS false.
The next production of my reviewer
again shows his delicacy and the refine
reiuctance.N the same generous feeling
that no doubt gave birth TO this entire
Article, charges me with upholding the
Ruttan system. | will be obliged If
some one will show me one word, figure
or sentence in my report that directly
or indirectly favorS any system, COM
pany or corporation.
Before answering his last conclusion
| wish to make statement i'll justice to
t'rof. Eberman regarding certain parts
Of the chemical analysis. A series of
accidents occurred that, while they do
not materially affect the general result,
should be explained. and | would also
state that it was my fault that they
were not all rectiiied. When we CON-
menced the survey, Nov. 10. we had
four glass Jars for collecting the all. made
alright with iron clamps and rubber
rims. The first two we sustained two
accidents, and one of the jars became
useless. Owing to private business it
was necessary for me to leave the city
Dec. 10, 1890. After working two days
We made calculations and discovered
That unless we got more jars we could
not finish by that time. Not another
Dnc with clamps could be procured; so
Three jars without. We soon discovered
that in spite of precautions the cover on
an unclamped jar would sometimes
give during the chemical reaction, and
some of the gas would escape, thereby
lcSSening the amount of carbOnic acid.
Of course, Prof. Eberman kept account
Of this.
Dee. Q, Q a. m., he brought me for the
FIRST time his chemical report of all the
schools except the Logan and Madison,
and stated that the above-described ac-
eident had occurred in Analysing the
specimens from four of the rooms con-
tanning pupils, and in three of the
empticS, and asked for Instructions re-
garding the matter. AS | had some
time previously notified him that must
have the entire report by D. ~. Dec.
., he Informed me that it would be i'm
possible TO complete the Logan and
Madison. and then collect and analyZe
The seven extra specimens within the
prescribed time. l, thinking the rooms
filled with pupils the most important.
requested him to do those if possible,
and let the rest go, knowing that they
could easily be done at any time after

doing his best, he could only complete
three of the eXtraS-the Washington,
Hawthorne and Cleveland-and- these
were handed me, together with the
Logan and Madison. Dec. 9, Z p. M. L

When you took up this report we were
on hand TO make this explanation, but,
as you know. no action was taken.
returning again to my friend from

theory sooner, the professor and my
self could have gotten together every
evening, compared our work, and, when
the figures did not fit the theory, make
them fit, and thus save ourselves much
trouble and extra work.
| will just touch upon his last point,
and will bore you no longer.
During his interview with me he
stated that The figures in my report
were correct, but that it was my conclu-
SiOnS that were all wrong"
Once more in his article his innate
modesty comes to the front, and he
apOlogctically and gently insinuates

Gentlemen, it is about the only state
ment that he makes in his entire TRADE

men, to take an honest and fair lot of
figures and facts, such as you have in
our report. juggle them up and draw
any such conclusions from the same, as
my friend thinks | should, and thereby
lend my aid and prostitute my official
capacity toward assisting in wiping out
of existence a system of heating and
ventilation that has been put into
tWenty-Seyen of our public schools after
mature deliberation by this Board, at
cost to the city of nearly 100000, for
the purpose of replacing it by some
other system that will cost the taXpay-
ers as much more, and in all probability
will not be in any particular an i'm

Yes, gentlemen, | am too ignorant for
this. and am thankful for it.
