Tom Swift and His Big Tunnel

I like reading these because of the view of the future as seen from the past.
But Tom in these early books has two servants.
One is a giant that is not very bright and refers to Tom as Master.
The other is an elderly ex-enslaved person who refers to Tom as Massa.
Neither of them speak standard English.
So I can only tolerate 1 or two of these a year.

It's amusing that Tom creates a new powerful explosive that he transports by train and ship without
feeling the need to tell anybody they are transporting it.
Also on a high speed train, it takes a week to get across the US.
