Potato and Celery Salad

For this salad you require half a dozen cold boiled potatoes, the inside of a small head of celery, and 2 tablespoonfuls of salad dressing. Slice the potatoes about a quarter of an inch thick, then lay them into a glass dish, wash the heart of the celery, cut every stick in very small pieces, then sprinkle them over the potatoes, and pour on the dressing before serving.
