4S centimeters (saj 19 inches) high by 53 centimeters (say 21 inches) 
wide. The map if mounted as a whole will cover a space 11 feet high by 
12 feet wide, and its scale will be i : 1,500,000. To pay for this map the 
Congress has received appropriations 10,000 francs each from the follow- 
ing "large countries" which are considered as " subscribers," and to 
each of which 100 copies of the map when completed will be sent, viz.: 
France, Spain, Austro-Hungary, Russia, Scandinavia, Germany, Great 
Britain and Wales. 
The "other countries" viz: Belgium, Holland, Denmark, Switzerland 
Portugal and Roumania are to divide amongst themselves 100 copies 
and jointly to become a subscriber. 
It occured to the American Committee that inasmuch as the object of 
the enterprize was less to make a map of Europe than to settle a general 
and far-reaching principle, the United States had as much interest in it 
as European countries, and should certainly have some of the maps. 
The only question to settle was, whether it shonld be ranked with the 
"large countries" or come in among the little ones as part of a subscriber. 
On consulting the map of the United States, the annual reviews of 
geological papers published, and the lists of geologists in the United 
States, the Committee was induced — ^let us hope not too rashly — 
to apply to the map committee for the recognition of its country as 
a large one capable of assimilating 100 entire geological maps. Patriotic 
Americans will not blame the committee for deciding thus, yet it may be 
stated that several thousand circulars setting forth these facts sent out 
by mail during the last three years to all the institutions of learning and 
scientific men whose addresses could be obtained either from the ex- 
change lists of the U. S.Geol. Survey, Cassino's Directory and the pub- 
lished members of Section E., A. A. A. S.. have thus far resulted in dis- 
posing of only seventy-eight copies. In both the circulars and in in- 
numerable articles contributed b}- the writer to scientific journals such 
as the Am.Journ. of Sci.; Science, Journal of the Franklin Institute, Am- 
erican Naturalist, the daily papers, and the published proceedings of the 
Am. Inst, of Mining Engineers, of the A. A. A. S., the Am. Phil. Soc. 
&c. &c., it has been again and again stated that the cost of the map to 
every subscriber will be 100 francs plus a few sous for transportation if 
delivered in Europe, but for American subscribers the sum has been 
fixed at twenty-one dollars ( $21.00) to cover freight &c. for all institu- 
tions entitled to receive educational publications free of duty. This sum 
will pay all expenses to the express or freight office nearest to such insti- 
tution. 
Individuals must pay in addition to this the duty which as nearly as 
it can be estimated now will amount to five dollars. (See the letters of 
Mr. Cadwalader, Collector of the port of Philadelphia, appended.) The 
cost of the map to an individual will hence be $26.00, all expenses paid. 
This will be the same price which will be charged to individuals in 
Europe with one dollar additional to pay all costs to the final destination 
of the map. But as a compensation, the individuals who help the Com-
