Beyond all doubt one of the most impressive features of the parade was the immensity of the crowd of spec- tators. From the Battery to Yonk- ers, a distance of about 12 miles, scarcely a foot of ground or roof space affording a view of the river, especially on the Manhattan side, was unoccupied. Along Riverside Park, from Seventy-second . street northward, the bank,. drives, roofs, windows, even trees, were packed sol- idly, as may be seen in the three views of the vicinity of the water gate at 110th street. .New York never saw its like before and it may. be long before it sees its equal. Clermont. The general design and construction of the Clermont and her machinery are sufficiently apparent from the ac- companying plans and photos. From reliable existing data the Clermont's dimensions 'were: Length, 150 ft.: beam on deck, 13 ft.; depth, 7 ft. As for model she may be said to have had none, being practically a paral- lelogram in plan with the ends point- ed to 60 degrees. Her draught was zZ ft. The original 'engines -were built in England by Boulton & Watt, the new ones, as well as the hull, by the Staten Island Shipbuilding Co. The single cylinder is 24 and 48 in. and designed to work with 20 lbs. steam. The paddle wheels are 15 ft. out- side diameter, with eight buckets 2 ft. x it. Tie poles ts:5. tt. 6. in- diame sey, 16 ft. long, set in 'brick work and arranged for wood fuel. The Half-Moon is 74.5 ft. long over all, 'between perpendiculars 58.7 it., beam 16.9 ft., depth 10 ft. draught 7 ft. The thought must have occurred to everyone who saw her that those who went to sea on her were a venturesome lot and that those who had the daring to cross the Atlantic in her possessed a courage nothing short of reckless. THE BALLIN SECTIONAL WATER TUBE BOILER. The present prejudice existing in the minds of steamboat men against small tube and pipe boilers has its foundation in the many shortcomings found to a greater or less degree in most steam generators of this kind. The reason for the preference given today to water tube bboilers of the horizontal tube type is that in these boilers the irdividual tubes may be 'TAE Marine REVIEW inspected, cleaned and repaired with- out disturbing others, while so far this has not been possible in a prac- tical. sense with any of the small tube or pipe iboilers. While the large horizontal tube boilers are capable of furnishing high pressure steam quick- er and on somewhat less weight than the cylindrical or Scotch boiler, they save little in space and add consider- able in cost and attention. Small tube boilers of the Thorny- croft and Yarrow type, while efficient, light and safe, have not found much favor for commercial vessels for the reason that the repair or replacement of tubes beyond the outer rows is impossible or difficult. Pipe boilers have been chosen prin- cipally upon their first cost. They are mostly built up from ordinary steam pipes with screwed fittings which have proven a continual source of trouble and expense. Cleaning the inside of the pipe is impossible and is not at- elementary forces in the 379 tempted at any time. In prac- tically all these boilers the sep- aration of steam and water takes place in the steam drum, into which the full contents of the tubes have to be discharged and where various kinds of more or less efficient contrivances are provided in the shape of baffles, dry pipes, etc., to separate the water and steam. With these facts in mind, it oc- curred to Fred A. Ballin, naval archi- tect and engineer, Portland, Oregon, that a design might be worked out in which it would not be necessary to circulate the mixture of steam and water into the steam drum, but which would confine the circulation to each section and effect a separation by individual sections. The outcome of Mr. Bal- lin's efforts in this direction is the Ballin Sectional Wlter Tube Boiler.
