llen from 944 to 572,
though, according to the increase of the population, it would have been
naturally 1,076.

Another heading on the prison records is "Juvenile delinquency," which
may include any form of youthful offense not embraced in the other
terms. Under this, in 1860, were two hundred and forty (240) females; in
1870, fifty-nine (59).

The classification of commitments of those under fifteen years only runs
back a few years. The number of little girls imprisoned the past few
years is as follows:--

1863......................408
1864......................295
1865......................275
1868......................239
1870......................218
1871......................212

CRIMES CHECKED AMONG THE BOYS

The imprisonment, of males, for offenses which boys are likely to
commit, though not so encouraging as with the girls, shows that juvenile
crime is fairly under control in this city. Thus, "Vagrancy" must
include many of the crimes of boys; under this head we find the
following commitments of males:--

1859..........2,829
1860..........2,708
1862..........1,203
1864..........1,147
1865..........1,350
1870..........1,140
1871............984

In twelve years a reduction from 2,829 to 994, when the natural increase
should have been up to 3,225.

Petty larceny is a boy's crime; the record stands thus for males:--

1857..........2,450
1859..........2,626
1860..........2,575
1865..........2,347
1869..........2,338
1870..........2,168
1871..........1,978

A decrease in fourteen years of 502, when the natural increase should
have brought the number to 2,861.

Of boys under fifteen imprisoned, the record stands thus since the new
classification:--

1864..........1,965
1865..........1,934
1869..........1,873
1870..........1,625
1871..........1,017

Of males between fifteen and twenty, in our city prisons, the following
is the record:--

1857..........2,592
1859..........2,636
1860..........2,207
1861..........2,408
1868..........2,927
1870..........2,876
1871..........2,936

It often happens that youthful criminals are arrested who are not
imprisoned. The reports of the Board of Police will give us other
indications that, even here, juvenile crime has at length been
diminished in its sources.

ARRESTS.

The arrests of pickpockets run thus since 1861, the limit of returns
accessible:--

1861............466
1862............30
