•So The Taconic — Marcou. 
a general map of the original Taconic area, nearly as exact and 
correct as Dr. Emmons' suppressed geological map of the agri- 
cultural report of New York. The general and local maps 
published by Logan and Hall, the two Hitchcocks, Dana, 
Wing, etc,, are absolutely valueless so far as classification and 
nomenclature are concerned. We see now, why the opponents 
of the Taconic system have such an interest in the suppression 
of Emmons' map, for all together to this day they have been un- 
able to give anything approaching its correctness and real value. 
The eastern boundary from the Canada line, to the state of 
New Jersey is good, and the western boundary along the east- 
ern shores of the Hudson river, all along the Hudson valley and 
lake Champlain, is exact in the main, and superior to any given 
since. 
In a foot-note i^Loc. cit. p. 309) Mr. Walcott says that he 
has "reason to state that 3,000 copies were originally delivered 
to the Secretary of State, of the State of New York, by the 
printers, and I think that copies can still be obtained from the 
said secretary's office, despite the published statement that the 
edition was stolen or destroyed." Such statement seems to 
mean that if Dr. Emmons had applied to the Secretary's office 
the 3,000 copies wanted for distribution with his final volume 
of the "Agriculture of New York," would have been delivered 
to him. The Secretary of State was not a geologist, and had 
no personal interest in keeping from its author an important 
map of a great report, made and paid for by the State; and 
its disappearance and suppression during all the life of Dr. 
Emmons, and even during fifteen years after his death, must 
have a reason. Every unprejudiced person will lay the blame 
at the door of those whose intei-est it was to suppress the 
Taconic system and all public marks of its existence. 
"The Geological sketch map of the Taconic range," published 
by Mr. Dana in 1882 ^tiart. Jour. Geol. Soc. London^ vol. 
XXXVI 1 1, p. 40S) does not contain a single spot of strata referred 
to its true stratigraphical position. The Primordial extends 
only from Burlington to opposite the entrance of lake George, 
the tvhole of the original Taconic area being- etitirely devoid 
of primordial strata. Mr. Walcott's geological map is not so 
sweeping; half of Washington and Rensselaer counties are
