CONTENTS: Preliminary Rbport On The Experimental Septic Tank At The University Of Kansas, John S. Worley. PUBLISHED BY THE UNIVERSITY, Lawrence, Kan. Entered at the post-office in Lawrence as second-class matter. PEELIMINARY EEPOKT OF THE EXPERIMENTAL SEPTIC TANK AT THE UNIVERSITY OF KANSAS. BY JOHN 8. WORLKY. With plates XXIX to XL. TN connection with the study of problems in sanitary engi- -- neering related to the rapid, efficient and economical disposal of sewage, a septic-tank system was installed south of the Fowler Shops, at the University of Kansas, and some analyses have been made of the effluent at various points in the system. The tank was built in the winter of 1903-'04, with the cooperation and under the supervision of Prof. W. C. Hoad, of the engineering department. The analyses of the effluent were made in the water-analysis laboratory. It is to be regretted that the series of analyses does not cover a longer period, but the end of the college year made it necessary to suspend operations. It is expected that the work will be continued by other students in the department. The objects of the experiments were to study the workings of a septic tank, to note the effect of aeration on the efHuent from the tank, and to see if, after thorough aeration, a second bacterial action could be secured in a second tank. A record was made of the approximate composition of the sewage treated, and the samples of effluent were taken at such points in the system as would show the efficiency at the stages mentioned. The main tank was situated at the mouth of the sewer leading from the Fowler Shops. It was built of brick laid in lola Portland c...

Many people fear snakes, and watersnakes in particular have one of the worst reputations of any snake found in North America. Some species are commonly mistaken for venomous cottonmouths, and a few may eat popular game fishes. Unfortunately, few people realize the important roles many watersnakes play in natural ecosystems and, consequently, they are still persecuted in many regions today. Seeking to overcome common misperceptions, J. Whitfield Gibbons and Michael E. Dorcas have compiled North American Watersnakes, the first comprehensive study of all fourteen species of watersnakes found in the United States, Canada, Mexico, and Cuba. Individual species accounts explore all aspects of the natural history of watersnakes in North America, including their behavior, physiology, life history, ecology, and conservation. Almost 100 color photographs accompany the text, illustrating all 14 species and nearly all subspecies. Supplementing the species accounts are detailed color maps depicting each species distribution and stunning black-and-white drawings by Peri Mason. Easy-to-use keys help readers to identify specimens at hand.
