MY GARDEN, 



When worms get into pots the plants are damaged, and to prevent 

 this the gardener stands his plants on ashes or on boards. The Earth 



or Lob Worm (fig. 993) is 

 about eight inches in length, 

 is hermaphrodite (Nos. 2

 viridis], which is discarded by the angler, and which 'lives under stones 

 in the field. 



In my garden there is great abundance of the Brandling (Lnmbricus 

 fcetidus). It is marked alternately red and yellow ; it lives in manure 

 heaps, and has an unpleasant odour, which clings to the hands after 

 touching it. It is a favourite bait for perch. 



LEECHES. 



We have Leeches in our lake. I have not determined the species, 

 but one kind is possibly the Hirndo piscium. 



FRESH-WATER SPONGE. 



We have one fine species of Fresh-water Sponge, which grows upon 

 the wall near the flood-gates, and also on the walls of the mill ; it is
