News about the telegraph

Well, my husband just informed me that they just sent a message from city to city via a telegraph. This amazes me that someone would be able to come up with this invention. It must have took a few long years to figure out how to construct something like that. From what I understand, it will help people send messages to others in different cities. The messages are sent through an electrical wires and come out on the other end as a code. This seems like it would be very helpful for large business owners. I do not believe that it will affect me out here on the farm.
