TURNIP. 
Turnips.were devoured, and of Turnips in the parts which were saved 
by repeated dressings.” 
On Sept. 18tli Mr. Jabez Turner, of Norman Cross, Peterborough, 
mentioned that a field sown with Trifolium incarncitum on August 30th 
was being much injured by some pest, and on Sept. 21st he forwarded 
specimens of Slugs which, with many others of the same kind, he had 
found that evening amongst the Trifolium , “ the plants of which have 
now nearly disappeared.” Mr. Turner further notes that the Trifolium 
was sown on Oat-stubble after Mangolds and Potatoes, and that the 
Slugs were smaller than the kind which usually does so much damage 
to Clover Ley Wheat. 
This Slug was the Limax agrestis, sometimes known as the Field 
Slug or Milky Slug, from its abundant viscous or milky slime. 
A great deal of loss both in garden and field would be saved by 
considering the above power of the Slug. 
Where a heavy dressing can be put on, as we may do on unoccupied 
land, so that wherever the Slug crawls there is the obnoxious stuff, it 
would soon exhaust its slime-producing power and perish ; but where 
there is a growing crop this can seldom be managed. Lime slakes 
rapidly in the dew of the morning or evening when the Slugs are out, 
which is the time for dressing, and if, as is frequently the case, it is 
thrown at a few days interval , it is too often waste labour. I have 
seen the Slug resting as comfortably in the slaked lime as if under a 
stone ; but, on the contrary, where the dressing is given as above at 
short intervals , there would be every reason to hope the pest would be 
got rid of.
