(p.28) "Note that if alcohol is used in the system as an
contd. anti-freeze, boiling may occur before the temperature
at which the red lamp operates.
"Therefore, under these conditions a more careful
attention to the thermometer is necessary.
"However, the shutters will keep the water temperature,
under normal conditions of use, below that at which
boiling of alcohol will occur."

(p.29) Water Level. Delete reference to accidental running
with closed shutters.
Suggest add: "If glycerine or ethylene glycol is used
as an anti-freeze the water level should be considerably
lower, and should only just cover the upper tubes of
the radiator core." (Otherwise we find there is
considerable loss through aeration and expansion of the
liquid).

Descending Hills. We have said for some years that
"it is never" necessary to change to a lower gear in
descending a hill. It has cost us nothing and the
practice is dying out rapidly everywhere. Compare
pages 115-118 of Am.book.

(p.30) Sideslip. "Greasy" surfaces. Suggest "slippery"
surfaces. Ice on the road is our chief trouble.

(p.31) "The coil being of the non-trembler type". Delete.
No trembler coils any more.
Frost. Notes not complete enough for practical use.
Suggest separate chapter on cold weather running, like
chapter XIII of Am.book.
Collision. See note P.116 Am.book.
Note re inspection after "even slight" collisions does
not appear appropriate to the use of bumpers. That is,
if the bumpers and their mountings are good such
inspection should not be necessary, and in cities like
New York is scarcely practicable.

Chap.II. Lubricants Recommended.

See Am. Instruction Book pages 33-36. Also, see
Chapter III of Am. book as a matter of suggestion
for rearrangement.
This gives -
First, on one sheet (with picture) a clear statement
of all the regular lubrication jobs.(what to do.)
(A serious omission however is draining crankcase every
1000 miles.)
