is pledged to a United States extension policy,
from which lie will not and cannot flinch. He
must be a diplomatic, if not a revolver and rifle
" fillibuster ;" probably ho will practise the
former, and wink more successfully than even
PIERCE at the latter. It seems evident, there-
fore, that, in the event of his election, England
must make up her mind to one of two things ;
either to accept the notice to quit, and leave
America, Cuba, and perhaps ultimately Jamaica
included, to the " regenerating " virtues of
WALKER. and his fellows, or to take henceforth a
firm position, and not yield an iota more. It is
clear that the insatiable spirit of slavery exten-
sion will endure no opposition till it has converted
the free Republics of Central Ana:rica into mar-
kets for the infernal slave-breeding interest.
Northward the resistance to extension of slave
territory is gathering strength, and probably will
soon become irresistible ; but the treachery and
violence which absorbed Texas, and converted a
free into a slave Republic, can easily accomplish
the same result with the feeble Republics in
question, and probably with Mexico also.
We may add that of the first six resolutions of
the " platform " one-half is directed against the
religious and political exclusiveness of the Know-
I nothings ; the other half to endorsing the latest
successes of PIERCE and the more rabid slave-
holders against the Free States. They especially
ratify the principles of the plausible Kansas Ne-
braska Act, by which the Missouri compromise
was abrogated, the formation of slave states
north of the parallel 39 deg. 30 min. permitted,
and the way paved for the brutal proceedings of
PIERCE and the Missouri slaveholders in Kansas
at the present time. Our readers can now judge
for themselves of the political merits of Mr.
Paßeds probable successor. We say probable,
because it is just possible, though not very likely,
that the disgraceful attack on Mr. SUMNER, and
the outrageous proceedings of the slavery Presi-
dent and his southerners, may unite parties in the
north against the nominee of the Democratic
Convention.

It is touching, yet gratifying, to read the last
Manifesto of the Poles, which appeared in The
Sun of yesterday. Again they compose themselves
to the attitude of patient hope in a righteous
PROVIDENCE, and of patriotic rejection of the in-
sulting and ensnaring Amnesty offsred them by
the new Russian EMPEROR. They feel deeply
that they were passed over at the Treaty of Paris,
and that semi-official Russian organs can speak of
this as releasing their Master from all compacts
in regard to Poland. They place, however, the
Amnesty in its true light. Its only distinction
from former snares of the same kind is that it does
not require them to undergo a judicial trial, but it
requires them to recant the errors of patriotism,
and it places them, for three years, under the sur-
veillance of the ignorant and brutal police of
Russia, before it gives them the poor civil rights
to which a Russianised Pole may aspire.
But the Amnesty does not, like many nobler
modern amnesties, merely require of them the
recognition of the existing Government—does not
recall their brother patriots from Siberia—does
not re-establish on their ancient footing the Uni-
versities of Warsaw and Vilna—does not provide
opportunities for the inculcation of their national
religion and teaching their national language—
does not give any hope of an internal and more or
less national Administration—and does not, above
all, even advert to the restoration of the rights
which were solemnly guaranteed the Poles by the
Treaty of Vienna. On the contrary it does, or
the EMPEROR'S speech does, refer to those rights
as "day-dreams !" Even peaceful Russian CzAits
cannot change their nature. They cannot become
respecters of national rights. Born in ambition
and shapen in cunning, selfish oblivion of the just
claims of others, and comfortable appropriation of
the fruits of crimes they might not like them-
selves to have committed, is the best that can be
expected of them. The "mild EMPEROR" at
Warsaw could not forbear from threatening the
Polish gentlemen whom he had summoned to
dance with him—from closing a compulsory fete
with the warning that he could punish all who
dreamed" of "happiness for Poland," except
ruder the blessed rule of the ROMAN-OFF family.
Saint ALEXANDER 11. is to be their chosen bene-
factor, or—Siberia and the knout for them.
Pleasant music, certainly, for the finale of a ball !

However the unwashed, unkempt, untended,
sprawling, pavement encumbering children of the
very poor contrive to reach the age of puberty
is, doubtless, to many a somewhat recondite
pussle. Admitted a large annual mortality
among them, the fact of a wonderful proportion
emerging from the sea of dangers and troubles
in which their infancy may be said to have been
spent still remains. The children of the rich
and well-to-do classes, notwithstanding every
care and attention, supply victims to disease and
accident in a far from satisfactory ratio, if the use
of that word may be prinitted in such a connection.
Ttiis ought not to be the case, judging by the
light of science and the laws of analogy. Never-
theless, it is so, and who is able to account for it ?
Is dame Circumstance after all a kinder stepmother
to the infant poor than she has been reported ?
Or are the advantages she holds out to the rich
not duly appreciated or turned to proper account?
Or does PROVIDENCE temper the wind to the shorn
lamb—in other words, make up for human ne-
glect by supplementing defective care ?

Who will undertake to tell Ili ? Whoever is in-
clined to do so may as well go further when he is
about it, and tell us how it comes to pass that the
mortality of London, comparatively speaking, so
little exceeds that of many of our pr.win,“.l-
- ? If he can do the one he can do the
other. Look at the position and condition of
London. Rising from the foetid banks of a pol-
luted stream, rank with malaria, interlaced or in-
terwoven with miles and miles of streets, squares,
and alleys, each with its peculiar garbage and select
hotbe I for fevers, the searching and purifying
winds of heaven might seem therein imp tent
to discharge their office. We leave the stagnant
marshes in the vicinity entirely out of count.
Water such as the lovers of the grateful element,
as its parkles cheerfully from the crystal fount, de-
light to quaff, there is none. The best we have
is only to be had after miles on miles of meander-
ing by dusty roads, over sunken meadows, past
brick kilns, smoking oppressive odours, and be-
neath a lazy length of vapid sunlight. For the
rest, what does Mr. SIMON say of them ? This is
ials description of the water supplied by one public
company, and taken from the corrupted and cor-
rupting Thames. It is " not only brackish with
the influence of each tide, but contaminated with
the outscourings of the metropolis, swarming with
infusorial life, and containing unmistakeable
molecules of excrement !" Enough. Turn to
the private pumps. What is said of the waters
obtained from them ? " Generally throughout
Loudon bad must be the condition of superficial
well waters, everywhere filtering from a dangerous
proximity to cesspools and sewers, everywhere
loaded with nitrate of ammonia, everywhere con-
taining evidence that they represent the drainage
!
of a great manure bed, and everywhere liable at
