This brought them to a long hall, which appeared to run through to Dupont street.

Much of this property is now owned by American-born Chinese.

The new structures erected on it were built to suit themselves.

Just how true it it we cannot tell, but there are those who claim that the underground dens of Chinatown are not wiped out by any means; even that some of them have been reconstructed on more extensive lines.

The doctor halted before a door at what seemed about midway in the long hall and proceeded to unlock it with a key.

"In with you, Alice," he said, and he pushed her gently into what seemed to be a small elevator.

Following her, the Chinaman crowded in behind her.

The doctor clutched the wire rope, and the machine started to descend.

"You see I'm letting you into all our secrets, Alice," he said with a grin. "I haven't required you to blindfold."

If this was an attempt to start a flirtation it failed, for Alice made no reply.
