reduces the grubs numerically, particularly if the ground 
has been dug level, so that the mixture gets washed into 
the soil equally. 
Gas Lime. Applied in the proportion of 40 bushels to 
the acre, this will kill nearly all grubs and insects, and 
will also manure the ground; but it must be ploughed in 
deeply before sowing. It is desirable that the ground 
should remain vacant for some time after.

are frequently, but erroneously, termed Black Beetles. In

the length of the body; the female has only rudimentary

Traps. ‘The ordinary beetle traps sold at shops, if 
baited with honey or sprinkled with beer, will catch large 
quantities. Basins, containing beer, or beer and water, 
and having a few sticks placed against the sides to 
form a road, will also be found successful; soda water or 
champagne bottles, partly filled with beer and water, or 
weak honey syrup, and sunk into the earth, will prove very 
effective traps if not too often disturbed.

COCOA-NUT FIBRE REFUSE. This is a mos | 
useful and inexpensive material, extensively employed by 
gardeners for various purposes. It is described as being 
free from any acid, saline, or tannin principle. The more - 
recent or fresh it is, the longer it will last, and the 2 
better it is for all purposes. Being very light and easily - 
worked, it forms one of the best materials for plunging 
small pots in, either in the propagating house or frame, _ 
in winter and spring, or outside, at any time. Cuttings _ 
of tender bedding plants are propagated by thousands _ 
annually in Cocoa-nut Fibre, as they root into it very - 
quickly. It may also be used for potting such plants as 
these, but not for any subjects that are to be potted _ 
permanently, as it retains too much moisture, and de - 
composes so quickly, As a surface covering for flower- 
beds in summer, and for affording protection to 
roots of somewhat tender plants during the winter mo
