Rio Shells argument for rise

In Cordillera the dikes do not generally appear to have fallen into lines of faults

I do not think so many faults in Cordillera, as in English Coal field - because lowered & raised - so on - but gradually & simply raised

No Faults in Patagonia enormous extent; if lowered again & covered no sign of upheaval

The action of sea A.B. will be to eat in the land in line of highest tidal action, this will at length be checked by increased vertical thickness (DZ) of mass to be removed & from the resistance offered to the greater lateral extension of the waves by the part beneath the band of greatest action not having been worn away.

If the level of the sea was to sink by very slow & gradual movements to line (2). The part (0) which was before beneath band of greatest action would now by degrees be exposed to it & the result would a uniform slope to base of cliff (Z) to which point the waves would not reach. If now the ocean should suddenly

In Patagonia the blending of pebbles & the appearance of travelling may be owing to successive transportal from prevailing swell, (as Shingle travels on the Chesil bank V. De la Beche) Ask Capt. F. R: how the swell generally & during gales would tend to travel on a central line of Patagonia.

NB. Mr Lyell P. 211 Vol III talks of line of cliff marking a pause

When mentioning pumice of Bahia Blanca, mention black scoriaceous rocks of R Chupat. & fall of Ashes of Falkner, ?how far is the distance?

Fossil bones black as if from peat - yet cetaceous bones so likewise of miocene period. Mem Bahia blanca P. 204 Vol III. Lyell

Owing to open faults in mountains to elevated strata in eocene lakes of France, & unequal action of Earthquakes on Chili & delta of Indus my belief in submarine tilting alone, must be modified. Moreover, the Volcanos from sea there burst out, after rise as did those aerial Volcanos in Germany

In the Valle del Yeso it is probable that point of Porphyry has been upheaved in a dry form
