Abstract
THE weather service of the American State of Maryland, maintained by the Johns Hopkins University, Maryland Agricultural College, and the United States Weather Bureau, receives a broad interpretation. The first volume of the series dealt with the physiography and meteorology of the State, the second presented the results of many years' study of the climate and weather of Baltimore and vicinity, while the third is connected with the former in so far as vegetation is dependent upon physiography and climatic conditions. The main purpose of the present volume is to present an ecological description of the vegetation, which is demarcated into three zones. The coastal zone spreads inland as far as the “fall-line”; thence to a contour line of 1500 feet extends what is designated as the “midland” zone, and a mountain zone comprises land above that altitude. The term, “fall-line,”it may be noted, is nowhere explained; reference to another source shows that at the junction of the Cretaceous or Cenozoic with older formations the rivers have falls or rapids.
