1. Sites inhabited
Worms are seen in extraordinary numbers on commons and chalk-downs. I have seen worms in black peat in a boggy field; but they are extremely rare, or quite absent in the drier, brown, fibrous peat. On grassy paths worm-castings may often be seen. On dry, sandy or gravelly tracks, hardly any worms can be found.
2. Nocturnal
At night worms may be seen, but usually with their tails still inserted into their burrows.
3. Wander from the burrow
On one occasion, five tracks were counted crossing a space of only an inch square.
4.Structure
The body of a worm consists of 100 - 200 almost cylindrical rings or segments.
5. Senses
The whole body of a worm is sensitive to contact.
6. Mental qualities
They pass the winter either singly or rolled up with others into a ball at the bottom of their burrows.
7. Food and digestion
They will eat particles of sugar and liquorice.
8. Calciferous glands
When a gland is completely filled with a single large concretion, there are no free cells, as these have been all consumed in forming the concretion.
9. Manner of prehension
A vacuum is produced beneath the truncated slimy end of the body.
10. Protection of burrows
A leaf being dragged a little way into a cylindrical burrow is necessarily much folded or crumpled.
When worms cannot obtain leaves, they often protect them with little heaps of stones. Whatever the motive may be, it appears that worms much dislike leaving the mouths of their burrows open.
11. Intelligence
The condition of 89 triangles (65 narrow and 24 broad ones) which had been drawn in by the apex was observed. The bases of only 7 of them were at all creased, being at the same time generally dirty. Of the 82 uncreased triangles, 14 were dirty at the base.
12. Excavation of the burrow
This is effected in 2 ways: by pushing away the earth on all sides, and by swallowing it.
13. Earth swallowed as food
Why the worms should have burrowed into the chalk in some places and not in others, I am unable to conjecture.
14. Depth of the burrow
Worms usually live near the surface, yet they burrow to a considerable depth during long-continued dry weather and severe cold.
15. Construction of the burrow
The burrows run down perpendicularly, or more commonly a little obliquely.
16. Ejection of their castings
I have watched worms during the act of ejection, and when the earth was in a very liquid state it was ejected in little spurts, and when not so liquid by a slow peristaltic movement.
17. The collapse of old burrows
It is certain that old burrows collapse in the course of time.
18. Their wide distribution
How they reach such isolated islands is at present quite unknown.
19. Brought up by worms
Objects of all kinds, left on the surface of pasture land, after a time disappear, or work themselves downwards.
20. Undermined by worms
The straightness and regularity of the lines formed by the embedded objects and their parallelism with the surface of the land, are the most striking features of the case.
21. Number of worms
There must exist 53,767 in an acre of garden.
22. Annually accumulated
Their chief work is to sift the finer from the coarser particles, to mingle the whole with vegetable debris, and to saturate it with their intestinal secretions.
23. Burial of the remains
Archaeologists are probably not aware how much they owe to worms for the preservation of many ancient objects.
24. Disintegration and denudation
Swallowed stones serve as millstones.
25. Aided by worms
A worm had bored through a flat circular disc of recently ejected castings, and heaped up a fresh vermiform mass in the centre.
26. Ledges on hillsides
If the accumulation of disintegrated and rolled worm-castings were to become confluent along horizontal lines, ledges would be formed.
27. Castings blown to leeward
Recent castings were found after a heavy gale blown up the slope.
28. Ancient mounds
A bed, even a vey thin bed, of fine earth is eminently favourable for worms.
29. Anciently ploughed fields
In attempts to ascertain how long crowns and furrows last, obstacles of many kinds were encountered.
30. Mould over the chalk
Castings ejected on chalk downs suffer some loss by the percolation of their finer matter into the chalk.
