What does this notation mean?
This is from a 1970 Washington state, USA, overview of archaeological sites. Can someone tell me how to determine what these numbers mean? I haven't been able to find any current guidelines to this notation.

I got a dishwasher shift last year, they had me cleaning stacks of baking trays that had accumulated for the 5 hour baking shift before my shift began, I worked from 9am to 6pm, is this a normal shift at your place? i was the only person there and they did not give me any training so i was really slow, i left after that day as i could not keep up with washing and putting things away as quickly as they wanted. I want to start dishwashing again for the money and experience but I don’t think I can come in and do a shift like that again. am I just bad at dishwashing or was this bakery/restaurant too demanding
