^phe fpikes ftick into their gums, and$make them fo fore, that they are in danger of being ftarved. The
llpleman, who related to me this faft, informed me,.that on the road he had a bill put into his hand, fignifying,
Mt at fuch an inn travellers might depend on having good hay for their cattle, without any mixture of
