Saute celery, onions, and ground beef; drain. Layer meat and vegetables in pans. Cover with ten (10 3/4 ounce) or two (50 ounce) plus one 10 3/4 ounce cans of mushroom soup. Dilute with 1/2 the same amount of milk or beef broth. Add a small amount of salt and pepper. Top with buttered crumbs. Bake 3 hours at 325 degrees. This is good served with cole slaw or assorted salads and rolls - using cake or bars for dessert.
