t pagan but papal idolatry--the Rome not of the Caesars,
but of the popes. While at Naples he ascended Vesuvius. Those masses of
lava, which seemed greater in bulk than the mountain itself, more
impressed him with the power of God than anything else he had ever seen.
As he looked upon that smoking cone, and thought of the liquid death it
had vomited forth, he said within himself, "What cannot God do!" He had
before felt somewhat of His Almightiness in love and grace, but he now
saw its manifestation in judgment and wrath. His visit to the Vaudois
valleys, where so many martyrs had suffered banishment and imprisonment,
loss of goods and loss of life for Jesus' sake, moved him to the depths
of his being and stimulated in him the martyr spirit.

When he arrived again in Bristol, June 18, 1879, he had been absent nine
months and twelve days, and preached two hundred and eighty-six times
and in forty-six towns and cities. After another ten weeks in Bristol,
he and his wife sailed again for America, the last week of August, 1879,
landing at New York the first week in September. This visit took in the
States lying between the Atlantic Ocean and the valley of the
Mississippi--New York and New Jersey, Ohio, Indiana, Michigan and
Illinois, Wisconsin, Iowa, Minnesota--and, from London and Hamilton to
Quebec, Canada also shared the blessing. This visit covered only two
hundred and seventy-two days, but he preached three hundred times, and
in over forty cities. Over one hundred and fifty written invitations
still remained without response, and the number increased the longer his
stay. Mr. Muller therefore assuredly gathered that the Lord called him
to return to America, after another brief stay at Bristol, where he felt
it needful to spend a season annually, to keep in close touch with the
work at home and relieve Mr. and Mrs. Wright of their heavy
responsibilities, for a time.

Accordingly on September 15, 1880, again turning from Bristol, these
travellers embarked the next day on their seventh mission tour, landing,
ten days later, at Quebec. Mr. Muller had a natural antipathy to the
sea, in his earlier crossing to the Continent having suffered much from
sea-sickness; but he had undertaken these long voyages, not for his own
pleasure or profit, but wholly on God's errand; and he felt it to be a
peculiar mark of the loving-kindness of the Lord that, while he was
ready to endure any discomfort, or risk his life for His sake, he had
