In Mexico the Federal government has helped several cities and towns to the amount of $45,000,000 towards aiding sanitation and the waterworks systems now in process of building in Mexico, City, Salina Cruz, Vera Cruz, Manzanillo, Mazatlan and others. The capital has received nearly two-thirds of the whole amount, of which half was spent on the difficult drainage system of the city and neighborhood. Vera Cruz has had appropriations of $4,000,000 for its waterworks in addition to another $2,000,000 furnished by the city itself. It has cost Tampico $2,000,000 for sewerage and waterworks systems in addition to $800,000 received from the government. Many cities have spent large sums in the same way without receiving government assistance, and many smaller towns are following the example of cither the independent or the government-aided cities, so far as regards sanitation work. Cities ranging from 50,000 to 100,000 population were without sewerage and waterworks systems less than a year ago; hut today towns of 10.000 and 20,000 population are beginning to take steps in the same direction, although in the well-drained mountain-towns the need of modern sanitation works is as nothing compared to that in the valley and tropical towns, where disease has to he constantly fought.
