These details point without much doubt to Picea. and most probablj^ 

 to P. nigra. Reference to previously determined localities show that this 

 species also occurs in the Don Valley. Toronto,' at Hamilton, Ontario, 

 and in the Leda clays at Montreal.- It is also to be observed that the 

 occurrence of this wood together with Larix americana in the Pleisto- 

 cene is quite in accord with their occurrence within the same area of 

 distribution at the present time.^ 



The external aspect ot this specimen shows conclusively that it had 

 been subject to the prolonged action of running water, and in the water- 

 worn character of the surface we have one of the best of evidences that 

 it represents drift material. 



DiSTICHITM CAPILLACEUM. 



The iraterial represented by numbers -t-t and 45 was found, upon 

 boilino-, to I'esolve itself chiefly into determinable mosses. The least com- 

 mon of these proved to be Distichinm capillaceutn. The fruit was entirely 

 wanting, but the leafy stems were in the majority of cases lemarkably 

 well preserved, so that there was no difRculty in instituting a direct 

 comparison with existing species. The locality where this material was 

 found is well within the range of distribution of the species indicated, 

 since specimens in the Herbarium of McGill University show that it is 

 found in abundance at the mouth of the Moose River, and presumably, 

 therefore, throughout the greater length of the river. 



Hypni'M recur vans. 



By iar the greater i)ortion of the peaty masses already referred to 

 consists of Hijpnum recurvans. In this, as in the case of Distichium, the 

 plants are remarkably well preserved, and it is possible to refer them to 

 existing species without much difficulty, since the sti'ucture of the leaves 

 is complete. The plants are, for the greater part, suflficiently large to 

 show the characteristic branching of Hijpnum, and although the fruit is 

 altogether wanting, the leaf characters define the species clearly. 



LyCOPODII'M, S[). 



Specimen 44 was found to contain a short section of a rhizome with 

 roots attached. The structure wan quite transparent through decay, 

 and showed a distinct central vascular axis. The structure was clearly 

 that of a lycopodiaceous plant, and in all probability the remains of a 

 Jjycopodium.
