This Canadian amber is transparent, varying from pale 
yellow, red to dark amber in color. Walker (1984) re- 
ported that the smallness of the amber grains (58% being 
less than eight mesh and only 3% larger than two mesh) 
was a point of difference from that of the generally larger 
masses characteristic of Baltic amber. He suggested that 
this might indicate conifers of types yielding little resin 
when wounded, in contrast to those which produced 
resin copiously in the Baltic forests. 
Eleven spectra were run on amber from Cedar Lake. 
Ten of these spectra were of specimens from the Harvard 
University Entomological Collections. All of these gave 
the same pattern represented by H 316 (Plate XVI), 
although some spectra were sharper than others. Also 
the pattern of amber from Cedar Lake, Manitoba, is 
similar to Ambrite (H 226, Plate XVI) from New Zea- 
land (USNM #7312). Both of these spectra, in turn, are 
similar to resin from A gathis australis, the Kauri pine 
(H 265, Plate XVI). Since 4. australis is noted for its 
capacity to produce large quantities of resin, it is a logi- 
cal source for fossilized resin from New Zealand. A 
possible Araucarian source, such as 4 gathis or related 
araucarians, for this Canadian amber is interesting and 
suggestive. More resins of members of the Araucariaceae 
need to be analyzed, before a definite correlation is made. 
Also the possible presence of A gathis australis (called 
Dammura australis Lamb.) in the Kreischerville, N.Y., 
deposits is noteworthy. Certainly, in the Potomac (AI- 
bian), Raritan (Cenomanian-Turonian) and Magothy 
(Early Cenomanian) Formations along the Atlantic 
Coastal Plain, members of the Araucariaceae were com- 
mon, and an araucarian-type resin could well be ex- 
pected. Araucarian leaf remains, i.e., 47aucarites longi- 
folia, are reported from Upper Cretaceous beds in the 
Rocky Mountains (Lance) by Dorf (1942), although
