leaves 1,700 slugs are said to have been taken in two days.’ One 
writer who had these leaves strewed over a crop of young parsnips, 
used a similar bait (savoy leaves) says that he destroyed 36,423 slugs 
at the leaves (besides 2,000 more killed incidentally) between 
7th October, 1841, and zoth May, 1842. Bran is much in favour 
as a bait. As an observer remarked in 1880, slugs seem to ‘scent 
it from afar and troop to it’; he had seen from twenty to thirty 
assembled round quite a small heap;* and previously another 
observer had remarked that it seemed to attract the creatures from 
all quarters, so that small quantities put down as baits became 
covered with them, ‘often a complete mass.’* Brewers’ grains, 
perhaps, are even more attractive. As stated in 1878, slugs will 
come to a handful of grains ‘from all directions,’ fifteen or twenty 
Pp 
had kept an account of the number thus trapped —_ the season, 
which, in May, had amounted to about 13,000.7 In 1889, the 
creatures’ liking for grains, and in fact for anything soaked in beer, 
s 
a pdivoiinesbis distance to get it.’* Beer or porter sweetened with 
Moist sugar is said to be ‘an effectual trap ;’ and when exposed in 
gardens in small vessels about two inches deep, many slugs and 
Snails, it is stated, drown themselves in it.® A six-inch flower 
saucer, half-filled with skim-milk and filled up with water when the 
milk turned sour, left on the ground on one occasion for four days, 
was found to contain more than 250 slugs, from a quarter of an inch 
to two inches in length, all dead.” It has been suggested, among 
others by Mr. C. T. Musson, that collectors might resort to similar
