arly eleven months, Mr. Muller had preached at least three
hundred and six times, an average of about one sermon a day, exclusive
of days spent in travel. So acceptable and profitable were these labours
that there were over one hundred invitations urged upon him which he was
unable to accept.

The third tour was on the Continent. It occupied most of the year
closing May 26, 1877, and embraced Paris, various places in Switzerland,
Prussia and Holland, Alsace, Wurtemberg, Baden, Hesse Darmstadt, etc.
Altogether over three hundred addresses were given in about seventy
cities and villages to all of which he had been invited by letter. When
this tour closed more than sixty written invitations remained
unaccepted, and Mr. Muller found that, through his work and his
writings, he was as well known in the continental countries visited, as
in England.

Turning now toward America, the fourth tour extended from August, 1877,
to June of the next year. For many years invitations had been coming
with growing frequency, from the United States and Canada; and of late
their urgency led him to recognize in them the call of God, especially
as he thought of the many thousands of Germans across the Atlantic, who

Pennsylvania, Maryland, District of Columbia, Virginia, South Carolina,
Georgia, Florida, Alabama, Louisiana, and Missouri. Thus having swept
round the Atlantic sea-border, he crossed to the Pacific coast, and
returning visited Salt Lake City in Utah--the very centre and stronghold
of Mormonism--Illinois, Ohio, etc. He spoke frequently to large
congregations of Germans, and, in the Southern States, to the coloured
population; but he regarded no opportunity for service afforded him on
this tour as so inspiring as the repeated meetings with and for
ministers, evangelists, pastors, and Christian workers; and, next to
them in importance, his interviews with large bodies of students and
professors in the universities, colleges, theological seminaries, and
other higher schools of education. To cast the salt of the gospel into
the very springs of social influence, the sources whence power flows,
was to him a most sacred privilege. His singular c
