The commercial results at Glasgow were so marvellous, that Mr. Redman simply referred to them as showing the great benefits that were produced by engineering works of the character described. The early reports of Smeaton, Telford, and Rennie showed that the river was navigable only for barges to Glasgow. At the present time the export and import tonnage of Glasgow amounted to the extraordinary sum of 2, 500, 000 tons; that was to say, the commerce of the port of Glasgow was equivalent to half the foreign tonnage of London or of Liverpool. That result, compared with the early condition of the river, was so remarkable, and so exemplified the effects of the works which had been executed, that Mr. Redman thought it was deserving of notice. With regard to the propagation of the wave, the Author of the Paper now before the Institution stated that, the difference of time between Greenock and Glasgow, at an early period of the history of the river, was from 2 hrs. to 3 hrs. In the report of Mr. David Logan, an old officer of the Clyde Trust, under date October 5th, 1835, the difference at that period was about 1 hr. 45 mins. 1 On the Admiralty chart of 1860, the difference was there defined to be 1 hr. 15 mins. ; and now, on the authority of the Author, it was stated to be only 1 hr. These results were remarkable. In the Thames there had been a corresponding acceleration of the tide due to similar works, but not in the same degree. Then, again, with regard to the height of spring tides--in evidence on the Clyde Navigation Bill of 1836, the spring tide at Port Glasgow was stated to be 10 ft. 10 in. , while at the Broomielaw it was 6 ft. The Admiralty chart of 1860 showed that at Glasgow it was then 12 ft. , and at Greenoc. . . This item ships from La Vergne,TN.<
