How did refrigeration work before electricity was widespread?

Question

I’m curious about the really old ice boxes, but I was really wondering about the ones from the 1800s that relied on coolant and some form of evaporation.

I can’t really picture how old is physics work without electricity.

Ice, Big fucking blocks of ice transported across the country, and then the other half of the year is winter, so y’know. free ice.
