small branches are used for hoops of tubs, &c.; the larger wood for cricket bats. 
From its lightness it is sometimes used, in this country, for waggon axles, From 
the facility with which it may be bent without breaking, itis in demand for 
boxes for druggists, perfumers, de. ‘

Nat. Ord. Magnoliacee. 
Called also the Tulip tree, and sometimes, though erroneously, Yellow Poplar. 
A remarkably beautiful tree, probably, taking all the dimensions, the largest we 
have in the Province. It attains a height of 140 feet, and the trunk is sometimes 
found as large as 8 feet in diameter in the Western States. It is extensively 
diffused, occurring in rich soils, and is most abundant in the western peninsula 
of Canada. Flowers in May and June. Trunk nearly cylindrical, and of uniform 
thickness to the height of 60 or 70 feet. But for the difficulty of raising, this 
would form probably the finest ornamental tree we have. The timber is valuable 
for building and cabinet purposes, forthe latter probably more used than that 
of any other tree except the white pine. From its cleanness ‘and: freedom from 
knots, and non-liability to warp or shrink, it is much used in railway car and 
carriage building, chiefly for the pannelling, being both easily wrought and durable 
and susceptible of a fine polish.

REMARKS ON THE FAUNA OF THE QUEBEC GROUP OF 
ROCKS, AND THE PRIMORDIAL ZONE OF CANADA. 
ADDRESSED TO MR. JOACHIM BARRANDE. 
BY SIR W. E. LOGAN, 
DIRECTOR OF THE GEOLOGICAL SURVEY OF CANADA. 
[A question of great geological interest, relating to the occurrence in Canada, of 
a Primordial Zone—synchronous, or partly so, with that recognised by Barrande 
in Bohemia, by Angelin in the Scandinavian Peninsula, and by the Officers of the 
British Survey, under Sir Roderick Murchison, in England—has occupied for 
some time the attention of our leading Geologists. More than two years ago, the 
able Palzontologist of our Geological Survey, felt constrained to acknowledge, on

tions of interesting papers, from the Comptes Rendus, the Annales des Sciences Naturelles, 
Poggendorf’s Annalen, and other French and German periodicals; together with occasional 
articies extracted from the proceedings of the Royal Society and other sources of a less acs 
cessible kind,—E. J. C.
