"No religious organizations were to own or operate primary schools nor were ministers or priests to be allowed to teach in such institutions. Only Mexican-born ministers and priests were to be permitted to carry on religious activities, and the states were to limit the number of such ministers and priests and their churches. The taking of monastic vows was prohibited on the ground that the state cannot permit an agreement which curtails the liberty of men whether for purposes of work, education or religion. Most of the provisions of Mexico's new constitution which would bear so heavily on mission activities have remained so far merely threats on paper, pending negotiations with foreign governments and the establishments of a settled policy within the country. In the meantime missionary activity continues much as heretofore." ARTICLES IN CURRENT PERIODICALS. Americans Journal of Botony, for October, Brooklyn Botanic Garden, $6.00 per year, 75 cents a copy.
