_To Destroy Slugs_.
A correspondent of the _Gardener's Magazine_ states, that after in
vain trying salt, lime, and dibbling holes for preserving young
cauliflowers and cabbages from slugs, he succeeded by spreading some
well cut chaff round the plants under hand glasses, and some round the
outsides of the glasses. The slugs in their attempt to reach the
plant, find themselves immediately enveloped in the chaff, which
prevents their moving, so that when he raised the glasses to give the
plants air, he found hundreds of disabled slugs round the outside of
the glasses, which he took away and destroyed.
_To make Kitchen Vegetables tender_.
When peas, French beans, &c. do not boil easily, it has usually been
imputed to the coolness of the season, or to the rains. This popular
notion is erroneous. The difficulty of boiling them soft arises from
an excess of gypsum imbibed during their growth. To correct this,
throw a small quantity of subcarbonate of soda into the pot along with
the vegetables.
