Clifford Ashley created this piece depicting two men shouting from the crow's nest in 1905.
Whalers would climb upwards into the crows nest to be on the lookout for whales.
When one was spotted, he would shout "Thar She Blows".
The whales usually surfaced and blew the water out of their blowhole on the top of
their back near the head.
This is so that they could clear it and be able to take another breath.
