Returned check from 1901 and a loan receipt from 1915

This is a returned check from my great great great uncle's father's Meat Market. He owned G. G Koerner Meat Market in Portland, North Dakota. He used to pay local farmers and ranchers directly for their beef and other meats. The second document is what appears to be an agreement to pay back a loan from the bank, given to my great great great uncle's step father. The date is 1915.
