96 THE REPORT OF THE No. 36 



Several other remedies are, however, to be found. In reading I happened 

 to come across several of them, a few of which are herewith described to bring 

 this study to an end, and thinking that it might interest you. 



In his book, " Recettes et Procedes," Tissandier recommends the following 

 mixture, spread on the ground. 



Caustic soda 40 gr. 



Quicklime 960 gr. 



Belief in " Les meilleures Recettes " say that in order to destroy slugs, it is 

 sufficient to spray the spots visited by these parasites, with a solution of 600 

 grammes of carbonate of soda dissolved in one litre of water. 



Mr. Anadyx surrounds the stem of vegetables with a border of old newspapers 

 and slugs disappear. ("La Nature," 1904.) 



Mr. Noel, of the Rouen laboratory of agricultural entomology, after several 

 tests, states that the most efficient destructive agent is copper arsenite. He prepares 

 it in the following manner: He mixes 1 kilogram of coarse wheat bran, 100 

 grammes of copper arsenite and about 250 cubic centimetres of water. When 

 the whole has assumed the form of a consistent paste, little balls are made and 

 distributed on the ground where slugs are expected to be found. After one 

 week, they will practically all have disappeared. (La Nature, 4910.) 



In order to attract slugs, Mr. Hardys covers cabbage leaves with rancid 

 butter and places them here and there in the garden; the next morning they 

 are thoroughly covered with slugs which are then easily destroyed. 



Finally, if the chickens are allowed in the garden, they can render valuable 

 services, but they must not be given dead slugs as food; they should be burnt 

 and buried deep. 



We did not have the necessary time to try all these remedies ; but we place 

 them before you for consideration. No doubt several experimentalists in this 

 assembly will want to give them a trial. The result of their experiments will 

 certainly be both useful and interesting.
