To sum up what the author has written in reference to the 

 "Mispec Group" it may be said that there is reason to think it has 

 an important bearing on the age of the plant beds above and below 

 it, geologically. 



That it has yielded no determinable land plants may be due to 

 its continental origin and the coarseness of much of the material of 

 which it is composed. It appears to be Lower Devonian, being 

 younger than the land plants from the "Fern Ledges" near St. John 

 and older than those from Perry in Maine, both of which have been 

 described by Sir. J. William Dawson. 



The group has been observed at various points from St. John to 

 L'Etang Harbour and on both sides of the Laurentian Complex, 

 which forms a ridge on the hills back of St. John, being in all cases 

 a distinct formation unconformable to the rocks above and below.
