The remaining difference is proba- <br />bly due to the fact that the water surface at the Union Depot was <br />higher than at the river, 1,700 feet distant, as shown by level lines run <br />after the flood. <br /> <br />28 <br /> <br />26 <br /> <br /> I <br /> ./ <br /> , <br /> J \; <br /> I <br />.
