Dear Sir

I enclose bill for instruments sent
by Adams Express according to your order.
I have no sun dial made for your latitude
we {insert symbo}have dials suited to all latitudes but these
are portable instruments and not fit for
constant exposure __ I suppose you
intend a tolerable large size to place
on a post for permanent exposure. I
can make one for {insert symbol}your latitude of such size
as you may think best _ of brass or
marble or slate __ for large size (12 to 20
inches dia.) slate or marble {insert symbol}does well __ 9 to 12 inch
in brass __

Also the wind vane should be made
to suit - the building on which it is
raised, if made large you can, perhaps,
have it made on the spot __ __ __

If you give me some particulars on these
points, I will attend to them as may
appear best __

Yours
Very respectfully

James Green
