الصفحة 284 - The figures for the last five years are given in the following table, from which it will be seen that there has been a considerable expansion in the output during the period covered : Building Materials 1899 to 1903 Material.
الصفحة 213 - The outer portions of the stream are necessarily deflected from the course of the great body of the water by the impediments of banks on the Irish side of the Channel, and by the tortuous form of the coast on the Welsh. The eastern portion passing Linney Head, rushes with great rapidity between the Smalls, Grassholm, and...
الصفحة 212 - An inspection of the plate will shew that the tide enters the Irish Sea by two channels ; of which Carnsore Point and Pembroke are the limits of the southern one, and Rathlin and the Mull of Kintire the boundaries of the northern.
الصفحة 226 - Thames than otherwise, and does not give so much water, whilst the ebb-tide runs out later, and marks lower ; but, upon the gales abating and the weather moderating, the tides put in and rise much higher, whilst they also run longer before high water is marked, and with more velocity of current, nor do they run out so long or so low.
الصفحة 213 - ... and strong rippling all round the edge, by which the bank may generally be discovered. Beyond this point the streams unite and flow on towards Howth and Lambay, growing gradually weaker as they proceed, until they ultimately expend themselves in a large space of still water situated between the Isle of Man and Carlingford.
الصفحة 208 - Hence in deep water vessels are safe from the waves of rivers which injure those on the shore. 18. The identity of the tide wave, and of the great wave of translation, show the nature of certain variations in the establishment of ports situated on tidal rivers. Any change in the depth of the rivers produces a corresponding change on the interval between the moon's transit and the high water immediately succeeding. It appears from the observations in this report, that the mean time of high water has...

Bass bank, and into Cardigan Bay; makes the circuit of that bay; and sets out again towards Bardsey at the other extremity of it; then sweeping to the N. by W. past the island and through the sound, it gradually takes the course of the shore, round Caernarvon Bay, filling the Menai Strait as far as Bangor; but the stream still continuing outside towards the South Stack, which it rounds, setting towards the Skerries at a rate of upwards of...
الصفحة 208 - The great primary waves of translation cross each other without change of any kind in the same manner as the small oscillations produced on the surface of a pool by a falling stone.
الصفحة vi - ... given fall and velocity, or certain known rainfall, were subjects almost untouched ; the source or supply of water in reference to the amount of rain was a subject which only a few canal and water- works engineers had investigated ; and they were not much disposed in olden times to communicate the practical experience acquired by the hard labour of years.
الصفحة 210 - See Experiments (11) and (12). The following three experiments are instructive as having been made on channels in which the maximum depth was nearly the same in all; but in (15) the depth remained constant to the side which was vertical. In (16) the sides had a slope of nearly 20°, and in (17) a slope of nearly 40°, so as to diminish the depth towards the sides. Maximum depth.
