These analyses, we think, will show conclusively, that quick 
sand has no fixed chemical composition ; that it differs too greatly 
in different localities, for its composition to be of any use what- 
ever as a guide in pointing it out. We examined closely, and 
compared the three specimens, taken from near Rome, with a 
large number of specimens of ordinary sand, from different locali- 
ties, with a view to see if there was anything peculiarly different 
in the form and fineness of the particles, but were unable to detect 
any essential difference whatever. But on subjecting them, with 
other specimens of sand, as well as soils, marl and clay, to similar 
condition, adding more than enough water to saturate them, they 
were all found to conduct themselves in a similar manner. 
In conclusion, then, we say, that if all such deposits as are sus- 
ceptible of assuming a partially fluid form, when subjected to the 
proper conditions, be included under the head quick sand, then 
our definition of it will be: any bed of earth which will receive 
into its mass enough more w-ater than it can take up, chemically 
and by cohesive attraction, to cause it to assume, when agitated, 
a partially fluid, or flowing state. 
POMOLOGY. 
The attention of our readers is called to the Pomological Rules 
adopted by the Executive Committee of the New York State 
Agricultural Society. The necessity for an uniform and estab- 
lished system, whereby originators or discoverers of new native 
vai'ieties of merit, and authoritatively introduce them to the public 
attention, has long been felt by horticulturists. Our readers are 
doubtless aware, that more attention has of late years been given 
to the introduction from abroad of new fruits, and also to the dis- 
covery and collection of new native varieties of merit than ever 
before. This has induced unprincipled men, for the sake of gain, 
merely, to rename old and discarded varieties, and to recommend 
new but worthless native seedlings, with attractive titles, as of
