The North is more of a fishing, shipbuilding, and lumbering area because of fast moving rivers made by the snow melt of the Northern states along with the nice coves and gulfs where they could make ships without too big of waves hitting their ships and almost sinking them and such when their building the boats. Also, they would lumber in the woods to get the shipmakers wood to build the boats with. They would get it to the shipbuilders by sending the wood upstream and let the river carry it to them. The North were relying more on the industry of lumbering and shipbuilding compared to the large scale farming of the South, and yes their was some farming in the North, but none to the scale of the people from the south and on the Norths farms, they didn’t use any slaves. Most of the North was actually were against using the slaves to do their work but some of the ships in the early 1700 were going to Africa to bring the slaves to the South and to the Indian Ocean area. They would use the money that they got from selling the slaves to go to places like China to get china and silk. The North also had huge textile mills along all of the rivers and sometimes they would interfere with the other mills because of the currents.
The South was more based on large scale farming due to the great soil that the South has. Since the farms were so big, they started to get slaves to farm for them instead of doing them all themselves. They were taking africans and some other immigrants and such to use just to produce the farms. Usually, farms only had two to three slaves, but their were some that had up to twenty slaves and they were considered the Cottonocracy.
