first indicated the sources which were advisable—the mountain 
springs come to light in the Alpine region not far from Schneeberg 
on the borders of Styria and of Lower Austria—and he it was who 
strove with tireless energy from 1863 to 1866 before the municipal 
council for the adoption of that project. It required seven years to 
complete the work, and it was on the 24th of October, 1873, that the 
new water commenced to flow and was greeted by the joyful cries of the 
people of Vienna. The good people had indeed reason to applaud; 
the mortality in the city was almost abruptly diminished by one- 
half. The regulation of the Danube was achieved in 1875. by opening 
a new river bed from Nussdorf to Stadlau. In the eyes of Suess this 
was but the very small beginning of a gigantic project, through which 
the Danube was one day to be set right across the whole Empire from 
Passau to the Gates of Iron; but this beginning, due to Suess more than 
to any other man, was of great benefit. It protected the life and prop- 
erty of the mhabitants along the banks of the river, bringing to the 
center of the capital the most beautiful river route of Austria and 
permitting the creation and development all along the regulated bed 
of the river of a new faubourg, built and equipped for commerce and 
industry. 
Even after retiring from affairs, and until the last years of his life, 
Eduard Suess continued to be interested in municipal and political 
struggles. He remained always the citizen of Vienna, with all the 
force of the beautiful word “citizen.” On the last night of every year 
he was accustomed, with some political friends, to make a pilgrimage 
to the Reichsbrucke, and there, above the muddy waters that flowed 
past as the years roll on, to drink a glass of wine to the glory and 
prosperity of the city, his city, one of the first objects of his thoughts. 
But, then, who could say how his thoughts were divided—what frac- 
tion went to the city, what other to the Empire, what to the earth, 
and what to humanity ? 
Contemporaneously with his political career, the scientific career of 
Suess developed, just as brilliant, just as fecund, it seemed, as though 
the first had not existed. In 1866 he published a memoir on the 
Loess;.in 1869, his ‘‘ Remarks on the salt deposit near Wieliczka’’; in 
1871, a study on the tertiary continental faunas of Italy; in 1872, 
his book on the structure of the Italian Peninsula; in 1875, his “ Die 
Entstehung der Alpen” (Origin of the Alps); in 1877, his considera- 
tions of the earthquakes of southern Italy and a little brochure, “Die 
Zukunft des Goldes’”’ (The Future of Gold). From 1878 on he com- 
menced the writing of ‘‘Das Antlitz der Erde,” and this was a labor 
uninterrupted for 30 years. He remained professor of geology at 
the university until 1901, or a total of 39 years. In 1901 he asked 
for retirement. At first replaced by Uhlig, one of his best pupils,
