Wasn't I beginning to feel shaky?
Yes; I should certainly faint before long.

But I didn't like the houses I passed.

They did not look fit for my adventure.

I must keep up till I reached a better neighborhood.
Anybody who knows Boston knows how cheaply my adventure ended.
Columbus Avenue leads out to Roxbury Crossing.

When I saw that the houses were getting shabbier, instead of finer, my heart sank.
