Handing tobacco for 10 or more hrs/day for $3 when i was about 12. It was bending over, picking up several tobacco leaves from a sled and handing them to a woman who looped a string around it on a stick. at the end of the day, the sticks of tobacco were hung up in a barn for curing.
When i got older I broke tobacco, stooping over breaking off several leaves that were ripe enough to cure and going to the next stalk. Cold in the morning from getting wet from the dew and hot as blazes midday and covered in tobacco gum. $7/day. I had to spend the money on school clothes.
My first regular job at 15 yrs old was working at the local grocery store 13 hours on Saturday for $7, 8:00am to 10:00 pm with an hour for lunch and didn't get off for supper and later also 3 1/2 hrs on Friday afternoon after school for an additional $3. This lasted the last 3 years of high school. i suppose there were no child labor laws back then or at least nobody cared.
