If there is any validity to a boundary, then it must separate regions that differ according to some specified criterion, such as terrain or language. The inhabitants separated by a boundary do not, except in very unusual circurnstances, live in complete isolation from each other. On the contrary, a constant stream of human interactions flows back and forth across a boundary. People travel, visit, migrate, intermarry, telephone, telegraph, attend schools, send letters, export raw materials, and import finished products across boundaries. If we can estimate, with reasonable precision, the effect o physical and cultural boundaries f (e.g. a river or political boundary) upon ewh type of interaction, we will possess a powerful tool for regional analysis and boundary studies. We might like to know, for example, how a long unbridged portion of the Ottawa River separates or unites the settlements on opposite shores when we specify, or wish to alter, a set of conditions. We can neither remove nor bridge the river, nor can we increase or decrease the size of the settlements, but we can
