A more thorough explanation:

Drover's Pass

A free pass given by a railroad company to the person who is responsible for driving cattle on a train.

When a farmer needs to transport their cattle to a different location, they hire a drover to take care of the animals during the journey. The drover is responsible for making sure the cattle are fed, watered, and comfortable during the trip. In order to travel with the cattle on the train, the drover needs a drover's pass. This pass is given to them by the railroad company and allows them to travel for free.

For example, if a farmer in Texas needs to transport their cattle to a market in Kansas, they would hire a drover to accompany the cattle on the train. The drover would receive a drover's pass from the railroad company, which would allow them to travel with the cattle without having to pay for a ticket.

Another example would be if a rancher in Montana needs to transport their cattle to a different part of the state. They would hire a drover to take care of the cattle during the journey and the drover would receive a drover's pass from the railroad company to travel with the cattle on the train.

A drover's pass is a special pass given to the person who is responsible for driving cattle on a train. This pass allows them to travel for free and accompany the cattle during the journey. The examples illustrate how a drover's pass is used in real-life situations when farmers or ranchers need to transport their cattle to different locations.
