          Bogart promised a work on fossil relics long ago &c.[etc.]&c.[etc.]
They seem to think, that if a book is but announced, it will
grow up itself without any labor. Just give us what you 
know and tell us in your preface that it is very imperfect
and intended as a mere sketch towards a system which
it is intended shall be adequate after further discoveries are
made.

You misunderstood me; if you suppose that I contemplate 
leaving Troy. I shall go to this Vermont plac, just
while my own lectures last, and then return. I calculate to
itinerate again next fall. I propose giving my usual
round of Chemistry and Geology in Pittsfield, Northampton
and Springfield. But I have made a curious contract for
the employment of my time during the month of Aug.
and part of Sept. I have engaged to take a geological
survey of Albany county at the expense of the Agricultural
Society. I have estimated the time required at 
six weeks. I am very glad to see the commencement of
such surveys and I intend to execute the task in a 
way, which shall be calculated to awaken a spirit
for such undertakings. An elegant copperplate map
will be struck off, exhibiting the rocks, [added: various] alluvia, [?},
marls, primitive sands, &c.[etc.], &c.[etc.], &c.[etc.]

You say but little about my geology. Now let
me tell you a word or two. Though I have occasionally
given a particular definition of a plant, and possess
the faculty of familiarizing the science of botany,
I do not consider myself as being in the way of improving
it essentially. But I think youare the most
accurate botanist in our country, and that you ought
to share the Science a-head half a century or thus 
a few years. I mean as it respects our country.
You know the only unexplained fiction this department
is the Cryptogamia beyond ferns. Some fool will soon
botch up something which will infest us a while and
[kick?] us back 8 or 10 years, unless you set about the work
in earnest. I know I should succeed in "getting many Vermonters &c.[etc.] [?]
