Bailey has shown that there is no convincMiig evidence of the 
presence of Ordovician strata in New Brunswick, and that much 
of what has been called Ordovician is either older or younger. 
This d(!monstration is given added importance by the fact that 
across the border in Maine, no Ordovician strata have yet been 
recognized. 
Gaspe. — This region is of unusual interest, for it was the first 
locality cited by Pana in support of his Taconic revolution. 
Dana based his early opinions largely upon the wi. tings of 
Logan, who supposed that the rocks of the Quebec Group were 
uno'mformably overlain by the Gaspe limestone.- 
J. M. Clarke, who has probably spent more time studying the 
exposures at Gaspe than any other geologist, has come to a dif- 
feient conclusion. This is best expressed in his article in the 
International Geological Congress Guide Book,' which carries a 
sketch of the geological structure as interpreted by him. In 
brief, his researches in this field have shown him that the whole 
series of Devon 'an limestones has been thrust over the strata 
fy^ " the Quebec group. 
\ 'Mth regard to the geological relations of the rocks of the 
Perct ■ siection, Clarke writes on page 102 of the paper quoted 
above:' "The uniformity of the inclmation in the steep fold is 
expresses <^ by the coincident dip of all the older beds, 80°— 85° 
SE. and this fold, steeply inclined to the north, involves beds 
from (Canibrian) Lower Ordovician into upper Lower De- 
vonian." 
And on page? .^^«^ he writes: "The mass [Bonaventure conglom- 
erate] everywhere .sheets the upturned broken and eroded edges 
of the vertical Ordovician-Lower Devonian clifTs, and it here 
reaches its northernmost hrait in recognizable expression." 
Conclusions. — Thus the conclusion that the Ordovician was 
closed by a period of folding cannot be supported by conclusive
