1916. Friend. — Are White J^or??is Injurious ? 47 
and I do not think anything has been done to banish" the 
worms out of it. They are found mostly about carnations 
and primroses. We are on the top of a hill, and the garden 
has a south aspect, and are well sheltered by trees, mostly 
beech. The rock here is Silurian, and there is no limestone 
nearer than Armagh, 14 miles off, consequently there is an 
entire absence of lime in the soil. I think your suggestion 
that the worms do not begin the attack is probably correct. 
I will try the lime and let you know the effect." 
Since the publication of my last paper in 1913, no further 
enquiries have reached me. It remains only to offer one 
or two concluding remarks. 
1. The range of plants which have been reported to suffer 
from worms is somewhat wide. Asters, carnations, lilies, 
primroses, fritillaries, and a number of other flowers have 
suffered, while of field and garden crops we have celery, 
tomato, swede turnips and others. Seeds are also said 
to suffer. The English list is much more extensive. 
2. The Enchytraeids found under suspicious circum- 
stances also vary greatly. Long ago Vejdovsky reported 
Achaeta from roots of Corydalis and other plants. At 
least three species of Enchytraeus {E. alhidus, E. Buchholzii, 
and E. parvulus) are suspect, while Fridericia agricola, 
F. galba, and F. hegemon may be placed in a similar category. 
3. The researches of Southern and myself during recent 
years have placed the study of Enchytraeids on a firm 
scientific basis, and it will not be a difficult matter in the 
future to give a satisfactory opinion whenever Oligochaets 
are submitted for examination. 
4. An earnest appeal is therefore made to all who are 
interested in the subject to supply material whenever 
available. Plants which are affected should be placed in 
tin boxes with as many specimens of the worms as possible. 
Boxes should not be punctured to supply air, as the worms 
crawl out and die. They can live indefinitely on the amount 
of air contained in any well -secured box, and will travel 
safely if a little moss is inserted when necessary to keep 
stones or dry soil from injuring them. Correspondence 
should be addressed to me as under.
