it would do very well for the end of a 
drawer knob. This is a very simple piece 
of carving in relief, and will not tax the 
skill of the operator very much. It is so 
simple that explanation is unnecessary. 
The beginner must remember one thing, 
and that is, never to use sandjDaper on 
carved work. All lines and angles should 
be left sharp and well defined, and this 
feature cannot exist if sandpaper is used 
on the work, as it will most assuredly 
destroy it. 
We have now said sufficient to give the 
beginner a fair start in the art of carving, 
and we hope he will continue to practice 
it until he becomes ambitious to try his 
skill on something more difficult, when 
we will, in a future chapter, be pleased to 
give him further aid. 
A DRIVE. 
BY MAEY H. WHEELEE. 
Up from her cavern a water-sprite eame 
For a drive on the moonlighted lake, 
And her transparent garments, all bright as a flame, 
Left a luminous trail in lier wake. 
Her ear was a diatom, shapely and strong. 
Which shone iridescent in gleam, 
And with bands of conferva she guided along 
Her tandem-hitched rotifer team. 
As, rearing and plunging, her steeds with a dash 
Went rapidly circling by, 
Through the sparkling water she went like a flash 
Of electrical light from the sky. 
The Daphnia held up her hands in surprise, 
" Bly eye ! " cried the Cyclops, " that's gay ! " 
And the Hydrachna winked with her two pairs of eyes. 
While the Cypris went swimming away. 
But alas for this turnout so jaunty and nice! 
When the moon marked the full midnight hour, 
A trout gobbled up the whole team in a trice, 
And the water-sprite fled to her bower!

possibly very young, and did not thrust 
out its cilia in two distinct tufts, as Cohn 
describes, although it may have had the 
power of doing so. At times it sprang 
quickly backwards and forwards, bring- 
ing its head where its tail was before. 
This object required for its comfortable 
elucidation a power of about six hundred 
linear. 
Among the common water plants, 
which are worth examining as the prob- 
able abodes of rotifers or infusoria, is the 
pretty little thing called "star- weed," 
some of which was obtained from the 
last-mentioned ponds, and on examina- 
specimen was only about 1-200". It was lion yielded a specimen of a tube-dwell-

AS usual the Kentish Town ponds were 
productive of objects, and among 
them were several rotifers not found i:»re- 
viously. The first of these was a very 
small worm-like thing, with one eye, a 
tuft of cilia about the mouth, and two 
toes at the tail end. Had it not been for 
the jaws, which were working like fingers 
thrust against each other, and Avhich were 
unmistakably of the Rotifer pattern, the 
animal might have been supposed to 
belong to some other class. According 
to the " Micrographic Dictionary," the 
Lindia torulosa is 1-75" long, but this
