Not so in the Pacific Southwest of the United States. What is called the "Mexican border" has become in a short generation a semi fiction, a theory in all but cartographical matters. Now, across the border, there is taking place a migration of workers and refugees, and perhaps of revolutionaries, of such a scale and escalation in annual numbers as greatly to affect the nature and propensities of American society, certainly in the Pacific Southwest, perhaps in a generation or so in the Republic as a whole.

        "What we are witnessing," writes the evidently pro-Hispanic Lester D. Langley, "is the re-Hispanicization of that once-Spanish domain in North America…" The migration itself, both reopdicatly and dangerously, is a response to wanted comfort in the United States, cheap labor erodes old loyalties. But it is also from a turbulent region of constitutional and economic habits alien to those of the United States, in prospective numbers and transported heritage an agent of territorial and cultural preemption perhaps incompatible with the cohesion of the American community, and presently out of control.
