REPORT OF THE CHEMIST. 101 
1. Cypris shields, fragmentary shelly particles. 2. Quartzose, horn- 
blende, porons calcareous rock, particles of quartz, scales of mica, round 
elay casts. 
Soil No. 3, (from the box,) lighter-colored than No. 2, less absorbent 
and adhesive, otherwise in texture closely reseinbling No. 2. Hlutria- 
tion disclosed, 1. Dark green amphibole grains, feldspar fragments, red 
sand-rock, mica scales. 2. Cypris shields, flattened, discoid, helical 
shell, (planorbis ?) 
There are few masses in these soils larger than coarse sand, so that 
they are good examples of material deposited in tolerably deep and still 
waters, the material derived chiefly from bhornbiendic and feldspathic 
clay rocks. There does not appear to have been any trausport of lime- 
bearing rocks, the lime found by analysis being that of the testaceous 
fresh-water coverings alluded to.

Along with the moisture are reckoned very slight amounts of vegetable 
matter which were in the soil, not, however, sufiivient to tinge the solu- 
tion of soda carbonate acting upon the soil for ove hour at a boiling 
temperature. There was here and there a slight bunch of fibrous roots 
as of grass. 
Saline matters soluble in water, solutions slightly alkaline.

It is evident on inspection of the analyses that these soils are not infer- 
tile. They are not wanting in any of the elements of soil which the 
Majority of plants require, and the inspection of the coarser parts of 
the clay shows that the mineral matter of which it is made up is of 
that character to supply by its degradation a reasonable amount tor
