Seite 126 - I ascertained, in 1829, some facts which throw light on the rate at which the sea gains upon the land. It was computed, when the present inn was built, in 1805, that it would require seventy years for the sea to reach the spot : the mean loss of land being calculated, from previous observations, to be somewhat less than one yard annually.
Seite 115 - From the very marly character of the Contorted Drift when traced westward it seems not improbable that that portion of the deposit is continuous with and passes laterally into the Great Chalky Boulder Clay. The general structure of Norfolk and Suffolk appears to show that the whole of the contortions are of one age, that of the greatest glaciation, or of the Great Chalky Boulder Clay, and it is probably to this period that the disturbances on the coast may be referred."* The remarks made by Mr.
Seite 126 - ... succeeding period less matter to remove when portions of equal area fell down. Between the years 1824 and 1829, no less than seventeen yards were swept away, and only a small garden was then left between the building and the sea.
Seite 113 - Fisher has spoken of such drift as " an ancient manufacture of ' whiting ' on a magnificent scale."* Mr. Reid observes that " The masses of reconstructed Chalk so common in the Contorted Drift are probably nothing but a later stage of the transported boulders, in this case so shattered and mixed with clay that they form a sort of transition to an ordinary Boulder Clay. From the very marly character of the Contorted Drift when traced westward, it seems not improbable that that portion of the deposit...

It was computed, when the present inn was built in 1805, that it would require seventy years for the sea to reach the spot : the mean loss of land being calculated, from previous observations, to be somewhat less than one yard annually. The distance between the house and the sea was fifty yards ; but no allowance was made for the slope of the ground being from the sea, in consequence of which, the...
Seite 57 - ... that there was a constant supply of arctic species brought by every tide or storm, while at the same time the southern forms had to hold their own without any aid from without ; and if one was exterminated, it could not be replaced. In this way, of two species, a southern and a northern, equally fitted for any station, the northern would have the best chance of surviving, and would probably exterminate the southern. The fact that not a single southern species appears for the first time in the...
Seite 128 - ... of the changes referred to upon our eastern coast. The period was probably within some few years after the Norman conquest, since shipping, it is acknowledged, came up to Norwich as late as the year 1078. Woodward, in the tract already quoted, says:
Seite 95 - ... he thinks I struck the right key for explaining the formation of this bluff. I think these cavities ought to throw some light upon the mode of accumulation of the Boulder-clay which envelopes the bluff; for when I saw them, they had been apparently exposed to view by its removal. They must therefore have been formed and filled in the interval between the formation of the bluff and its envelopment in Boulderclay.
Seite 83 - a difference as great as between the south of England and the North Cape at the present day, and sufficient to allow the seas to be blocked with ice during the winter, and to allow glaciers to form in the hilly districts.
Seite 79 - Lyell's works all cont&in essentially the same account of the Cromer Till and Contorted Drift. In 1845 Joshua Trimmer published a paper in the Geological Society's Journal, and in 1851 he gave a further account of the beds, suggesting that the contortions had been formed by the melting...
