was then passed over a revolving cylinder, where it was further 
washed and the phosphate gravel separated from the stone. The 
other dredge appeared to work an Archimedes screw or some 
such device that brought up the mud; it was raised to the re- 
volving cylinder, where a separation of the mud and gravel was 
effected, as in the other dredge. The phosphate was culled and 
separated from the stone, as in the previous case. 
Localities for Phosphate of Lime in New Brunswick. 
These are few, but are of interest, as compared with similar 
deposits in other parts of the world. 
A deposit occurs in a bed of fossil shells (Lingulella), two 
or three inches in thickness, that occurs in the sandstones at 
Dunn’s Ledges, on the east side of Courtenay Bay, at its head. 
Lingulella shells are largely composed of phosphate of lime, and 
if they were in sufficient quantity might form an available source 
of phosphate; but the bed is too small to be economically avail- 
able. 
Another locality known to me is at Hanford Brook, in eastern 
St. John County. Here it occurs in scattered nodules in a bed 
with Cambrian fossils, and was collected by Messrs. W. D. 
Matthew and G. Van Ingen, when studying the Cambrian fauna 
of that place. The occurrence is very similar to that in the 
phosphate deposits of South Carolina, where we find fragments 
and casts of Tertiary bivalves; just as at Hanford Brook the 
phosphate nodules are replete with the detached parts of the 
trilobites of the much earlier Cambrian Time. 
These phosphate nodules in the sandy shales of Hanford 
Brook did not seem to me to be in quantity sufficient to be avail- 
able for the manufacture of fertilizers.
