Three aquifers of diverse lithology and hydraulic character form the ground-water reservoir in the Roswell basin. The main aquifer, the carbonate aquifer, is developed in carbonate rocks of Permian age. It is the source of about two-thirds of the ground water pumped in the basin and receives more than 90 percent of the recharge to the basin. The second most important aquifer is the shallow aquifer which lies near the Pecos River in beds of sand and gravel of both Permian and Holocene age. About one-third of the ground water pumped in the basin comes from the shallow aquifer. Prior to pumping, the main source of recharge to the shallow aquifer was probably ground water leaking upward from the carbonate aquifer. Since pumping began, the main source of recharge to the shallow aquifer is probably return flow of irrigation water pumped from the carbonate aquifer. Natural discharge of ground water from the shallow aquifer into the Pecos River causes a gain in th.e base flow of the Pecos River in the Roswell basin. The third aquifer, the shallow-artesian aquifer, is in red beds and evaporite beds of Permian age. This aquifer overlies the carbonate aquifer and underlies the shallow aquifer. The shallow-artesian aquifer acts as a minor aquifer and also as a semi-permeable unit which partly confines ground water in the carbonate aquifer. Vertical permeability of the shallow-artesian aquifer is variable and depends on the lithology and thickness of the aquifer. Hydraulic head in the shallow-artesian aquifer also varies quite widely depending on the depth to which a well penetrates the aquifer. All ground-water aquifers in the basin transect formational boundaries and are therefore not closely related to the named geologic formations. A flow net analysis of the carbonate aquifer and of the shallow aquifer imply that geologic structure is important in the movement of ground water in the basin by limiting the transmissivity of the shallow and carbonate aquifers, by forming the present pattern of surface water drainage, and possibly by the contamination of fresh ground water by highly saline ground water. The flow net analysis also shows areas of recharge to the shallow and carbonate aquifers, and areas where the carbonate aquifer looses water to the shallow-artesian aquifer and to the shallow aquifer.

This study examines a number of aspects of the Johnson Temperament Analysis based on the responses of 48 male graduates in the Department of Education at the University of British Columbia. Item difficulty is considered from the reports of 39 students. The mean number of difficult items per student is 21.6 or 12% of the total. It is found that the difficulties can be classified under five headings: (a) Lack of experience with the topic. (b) Difficulties of comprehension. (c) Difficulties of evaluation. (d) Response dependent upon circumstance. (e) Two or more notions in one question. It would appear that a number of these difficulties could be avoided if a revision of the Analysis were undertaken. The adjustment of the group in terms of the Analysis is considered. The means are in the acceptable zone or better in all traits except Cordial, where the mean lies at the borderline between acceptable and improvement desirable. Age differences are not found to be statistically significant. There is some slight advantage of better adjustment in terms of the Analysis for the older group. Reliabilities of the trait tests, calculated by the split half technique are found to range from .32 to .82. In general these support the published figures of the test author. A phenomenon of difference between the first and second halves of the Analysis is noted. No definite conclusions are presented to account for this, but it is suggested that further research might determine the advisability of having unscored practice items at the b beginning of such inventories. The inter-correlations of the trait tests are calculated by the product-moment formula and are found to be comparable to the tetrachoric r's reported in the Manual of Directions, The former are factored by the Centroid Method and five factors extracted. The axes are rotated by the single-plane method and a simple structure obtained. This is discussed in terms of Thurstone's criteria and is considered to be reasonably satisfactory. An attempt is made to identify the factors obtained, one being named with a high degree of assurance. It is Factor II, Social Introversion-Extraversion. Factors I and III are identified with some assurance as Emotionality and Rathymia respectively. The remaining two factors are most tentatively, and with considerable reluctance, named as Objectivity and Cooperativeness. It is suggested that, if a shorter form of the Analysis be required, traits D and H would give a fair index of the general adjustment of the individual in terms of the five factors named. It is felt that, in the case of the 48 students used as the basis of this study, the nine traits defined by the test author are not distinctly measured. Since the group is small and homogeneous, no generalizations to the general population are made. / Education, Faculty of / Graduate
