The soil resulting from, and lying over this formation is 
naturally and very perceptibly inferior, to that produced by 
the disintegration of the trap rocks of the North Mountains, 
and the neighboring sandstone, its vegetation being less lux- 
uriant, and requiring for its culture greater labor from the 
husbandman. This is a fact which a traveller in passing 
through the country, cannot fail to observe. The soil has 
been much improved of late years, and the present state of 
agriculture in Nova Scotia, is much indebted to Mr. ohn 
Young, the author of a series of interesting and practical 
letters published in Halifax under the signature of “ Agrico- 
la,” and which resulted in the formation of several agricul- 
these dykes more particularly in another place, as also the 
patch of granite represented on the map in Annapolis coun- 
, which is undoubtedly subordinate to the clay slate, and 
all the other rocks in Nova Scotia... 5 
The bed of iron ore before alluded _ to is apparently six- 
teen feet wide, though from. its not having been explored at 
the time we visited it, so.as to present the contiguous strata 
of slate, we cannot state the exact width with certainty. 
Its direction, like that of the strata in which it is included, is 
north 60° east, and. is traceable for a considerable distance 
into the forest, until it is entirely obscured by the soil and un- 
derbrush.—’ on the surface from which considerable

it contains fifty per cent of pure iron, a very near pam 
tion to the truth, as proved on assaying the ore in the eruci- 
ple, and making an allowance for the carbon combini 
with it in the process. Some specimens of this ore in whi
