The Urban Pattern of Denver, Colorado

pressed ' many comments of praise. Favorable letters were received from a number of teachers. Several teachers said that due to the interest shown by the pupils in developing the survey , they had made further studies of their districts. The limitations of the project on the mapping of Wayne County or perhaps one may say any county project of this type, are quite large in number. Among them the following may be listed : 1. The project being voluntary with the schools, the director could not hope to get all. of the school districts to cooperate in the mapping. 2.The teachers in a few of the districts were incompetent to direct the pupils in the collection of the necessary „data for the survey and others were indifferent. 3.Some of the teachers looked upon the survey as too much work or saw little or no value in it. 4.The critical attitude of farmers in a few districts made it impossible for the pupils to collect the necessary data. 5.Some of the schools had too few pupils to attempt the mapping of the district and in others, the pupils were too young to carry out the survey. Annual Variability Rainfall Maps of the Great Plains EARL E. LACKEY The University of Nebraska, Lincoln In any field of research the worker must be certain that his tools are adapted to the requirements of his problem. This is especially important in the field of geography where the researcher- so frequently dpends on tools constructed for use in other fields of study. This paper deals with measures of central tendency and of percentile variability calculated from over 500 weather stations as applied to the making of rainfall maps- of the Great Plains. Vertical bar graphs showing these measures for selected stations on the Great Plains are presented . One of the maps shows central tendency (50 per cent map) by use of the median annual rainfall for each of the stations of the region, and four maps indicating condition of annual \'ariability—20, 40, 60 and 80 per cent cf the time, respectively. Note: Maps, graps, and discussion will appear in an early issue of The Geographical Review. Note—Maps, graphs, and discussion appeared in the October, 1937, issue of the Geographica] Review, Vol. 27, page 665. The Urban Pattern of Denver, Colorado MARGARET FULLER BOOS and HERBERT E. WINCHESTER University of Denver A map of the urban pattern of Denver was prepared by the class in Human Geography at the University of Denver during the Winter Quarter of 1937. Each member of the class was assigned a section of the city for survey and mapping in color on a regular base map. Types of houses, commercial interests, business centers, churches, educational institutions, parks, playgrounds, etc., were investigated and plotted. The parts were assembled and the map, mostly uncorrected , was presented. A brief summary of the historical background of the city was related to the growth of its parts. Present tendencies in expansion and topographic advantages and limitations were noted . Future expansion and its origina were forecast. (33) ...
