In Tuck Everlasting how do the Tucks earn a little extra money?

Angus Tuck and Mae Tuck make little trinkets and household items to sell.  Some of the examples that are given in the text are a model ship, wooden bowls, and wooden cooking utensils.  The text says that Angus does the carving and that Mae does necessary sewing.  

Jesse and Miles Tuck are a different story though.  They both get odd jobs wherever they can find work.  Miles has better luck finding work, because he looks old enough to get a variety of jobs.  Mae tells Winnie that Miles prefers working as a carpenter or a blacksmith.  In either case, Miles earns his money by hitting stuff with hammers.  Jesse's problem is that he doesn't look old enough to have very many types of jobs.  Mae tells Winnie that Jesse tends to work in farm fields or in saloons.
