Photograph of a partially completed pattern of windbreaks in eastern Foard County, Texas. The barren areas paralleling some windbreaks are not always due to sapping—incomplete patterns permit heavy, sterile sand to drift up to the windbreak on exposed sides. This situation can eventually be remedied by completion of the pattern and the planting of legumes on damaged areas. TX-79, 510.

The problem of this study was to find ways of improving and enriching the curriculum through the use of the intelligence quotients obtained from the California Test of Mental Maturity. To reveal some of the needs of the curriculum and also to reveal the possibilities and limitations of testing for intelligence, statistical relationships between intelligence quotients and academic achievement as measured by both teacher marks and achievement tests were determined.
