a criterion for the character of their present white population or the
condition of the slaves. Those laws were enacted for the most part in
seasons of particular alarm produced by attempts at insurrection, or when
the black inhabitants were doubly formidable by reason of the greater
proportion which they bore to the whites in number and the savage state and
unhappy mood in which they arrived from Africa. The real measure of danger
was not understood but after long experience, and in the interval the
precautions taken were naturally of the most jealous and rigorous aspect.
That these have not all been repealed, or that some of them should be still
enforced, is not inconsistent with an improved spirit of legislation, since
the evils against which they were intended to guard are yet the subject of
just apprehension."[8]

Wherever colonial statutes were silent the laws of the mother country
filled the gap. It was under the common law of England, for example, that

the poisoning of their master, duly convicted of petit treason, and
executed--the woman as the principal in the crime by being burned at the
stake, the man as an accessory by being hanged and his body thereafter
left for years hanging in chains on Charlestown common.[9] The severity of
Anglo-American legislation in the seventeenth and eighteenth centuries,
furthermore, was in full accord with the tone of contemporary English
criminal law. It is not clear, however, that the great mitigation which
benefit of clergy gave in English criminal administration[10] was
commensurately applied in the colonies when slave crimes were concerned.
Even in England, indeed, servants were debarred in various regards, that of
petit treason, for example, from this avenue of relief. On the other hand
many American slaves were saved from death at the hands of the law by the
tolerant spirit of citizens toward them and by the consideration of the
pecuniary loss to be suffered through their execution. A Jamaican statute
of 1684 went so far as to prescribe that when several slaves were jointly
involved in a capital crime one onl
