Anne says the work is tedious and makes them dizzy. She says that it is the sort of work that people do in prisons.

We have a new pastime, namely, filling packages with powdered gravy. The gravy is one of Gies & Co.'s products. Mr. Kugler hasn't been able to find anyone else to fill the packages, and besides, it's cheaper if we do the job. It's the kind of work they do in prisons. It's incredibly boring and makes us dizzy and giggly.
