and each piece is commonly found to contain from four to eight 
wireworms, and often Julus worms (“false wireworms,” or snake 
millipedes). In the spring of 1883, a field growing Spiraea 
japonica was thus treated, 
with the result that about 
80,000 wire-worms and Julus 
worms per acre were captured 
and destroyed. 
The Eelworm. — The 
stem-eelworm, Tylenchus 
devastatrix, is familiar to 
English farmers on account 
of its presence in clover 
plants smitten with clover 
sickness, and in oat plants 
suffering from tulip-root. Dr. 
Ritzema Bos has discovered 
it in a number of other plants, 
which, for tlie convenience of the reader, we have arranged in the 
following tabular form. : —

Besides the foregoing, there are enumerated several species of 
Narcissus, Scilla, and Hyacinthus, and also a moss {Ilypnum 
cupre.ssiforme), making in all thirty-six species, belonging to sixteen 
natural orders. It would appear, therefore, that the stem-eelworm 
is likely to be widely diffused in gardens, arable fields, and grass 
lands, whilst it is highly probable that further investigation will 
add to the list of plants liable to be infested by this minute pest. 
In the case of some species the eelworm seems only occasionally to 
wander into the plant, and not to disfigure it, whilst in other cases 
it becomes parasitic in great numbers and leads to plant-sickness.
