Not illustrated. 1908 edition. Excerpt: ... the curve as it entered the tube. The experiments on the submerged tubes, with entrance having square comers and of lengths varying from thirty-one hundredths feet to fourteen feet, have been designated by series, (Numbers 1 to 7), the tubes being shown in detail on Plate V. In series Number 1, the length of the tube was three and threequarters inches, equal to thirty-one hundredths feet, the same as the thickness of the bulkhead wall, the opening being cut through this wall at an angle as near ninety degrees as possible. The roughness from the effect of the saw was taken off with a smoothing plane, but sand paper was not used. The end of the wood was exposed at the sides of the tube as shown in the details'. In Series Number 2. the length of the tube was made equal to sixtytwo hundredths feet, double the length of Series Number 1, by adding wooden strips on the down-stream side. These wooden strips were surfaced and fitted closely to the down-stream edge of the previous tube so that the effect of the joint was practically eliminated. In Series Numbers 3, 4, 5 and 6. the length of the tube in each wise was made double the length of the preceding series number, becoming respectively one and twenty-five hundredths feet, two and one-half feet, five feet and ten feet. In Series Number 7, the length of the tube was made fourteen feet, about the extreme length possible with the arrangement of bulkhead and weir channels at that time. The outlet end of the submerged tube (with the single exception of the tube fourteen feet long, termed 7c') projected into the water on the down stream side of the bulkhead and was firmly braced to the sides of the ten foot channel, the braces being arranged in such a way as not to interfere with the flow through...
