out, before we sighted land, that we was crowding the land somewheres, if
he had thought of one thing; and when we asked him what, he said:

"These clocks. They're chronometers. You always read about them in sea
voyages. One of them is keeping Grinnage time, and the other is keeping
St. Louis time, like my watch. When we left St. Louis it was four in the
afternoon by my watch and this clock, and it was ten at night by this
Grinnage clock. Well, at this time of the year the sun sets at about
seven o'clock. Now I noticed the time yesterday evening when the sun went
down, and it was half-past five o'clock by the Grinnage clock, and half
past 11 A.M. by my watch and the other clock. You see, the sun rose and
set by my watch in St. Louis, and the Grinnage clock was six hours fast;
but we've come so far east that it comes within less than half an hour of
setting by the Grinnage clock now, and I'm away out--more than four
hours and a half out. You see, that meant that we was closing up on the
longitude of Ireland, and would strike it before long if we was p'inted
right--which we wasn't. No, sir, we've been a-wandering--wandering 'way
down south of east, and it's my opinion we are in Africa. Look at this
map. You see how the shoulder of Africa sticks out to the west. Think how
fast we've traveled; if we had gone straight east we would be long past
England by this time. You watch for noon, all of you, and we'll stand up,
and when we can't cast a shadow we'll find that this Grinnage clock is
coming mighty close to marking twelve. Yes, sir, I think we're in Africa;
and it's just bully."

Jim was gazing down with the glass. He shook his head and says:

"Mars Tom, I reckon dey's a mistake som'er's, hain't seen no niggers
yit."
