What sorts of work does Crusoe do for his new master at Sallee?

Crusoe was made a slave by the Captain of the ship.

The usage I had there was not so dreadful as at first I apprehended; nor was I carried up the country to the emperor’s court, as the rest of our men were, but was kept by the captain of the rover as his proper prize, and made his slave, being young and nimble, and fit for his business.

But this hope of mine was soon taken away; for when he went to sea, he left me on shore to look after his little garden, and do the common drudgery of slaves about his house; and when he came home again from his cruise, he ordered me to lie in the cabin to look after the ship.
