Double Camellias may be Propagated by Cuttings. —Double Camellias 
may be propagated by cuttings, but like the Yorkshireman’s mare which had 
only two faults, being very shy to be caught, and good for nothing after she was 
caught, the Double Camellia is difficult to strike, and good for nothing after 
it is struck. Single flow'ers are natural flowers, double flowers are only monsters, 
and require extra care and extra nursing. An industrious step-mother or foster- 
mother is requisite in such cases; as in rearing a favourite calf, w r e are sometimes 
obliged to give him the milk of two cow's. So to rear a favourite sheep, we put 
it to a more industrious ewe than its natural mother. All budding and grafting 
is founded on this principle, and the process of grafting is merely the striking 
oft’ cuttings in wood, instead of striking them in the soil. The expense is the 
same, and the result affords superior flow'ers, and superior fruits. 
A bud or graft comes sooner into flower and fruit than a cutting or seedling, 
and a promising seedling fruit tree will do better cut off and grafted upon its 
own stock than if not grafted at all. This simple practical result throws great 
light on the science of Vegetable Physiology. The pith and wood being divi¬ 
ded, they never unite again, but the sap in the graft unites with the sap in the 
stock, and plasters over the w'ound as it were, which is still visible in the oldest 
trees w'hen sawn down the centre. In cutting up old apple-trees this winter, I 
have been able to distinguish the difference between whip, tongue, and crown- 
grafting, all of which are blemi hes, but of no more consequence than the twigs 
w'hich are cut off the stem to make the tree a standard instead of a dwarf. Thus 
we see a graft or cutting is ripened, or ripe for the production of flowers or 
fruit, but the cutting from so many fresh roots becomes in a manner changed in 
its nature, and is indeed a new' plant. Whereas the bud or graft is merely trans¬ 
ported to a different soil, and flourishes in proportion to the congeniality of the 
stock. On this point hangs all the mystery of grafting, &c. For instance, the 
codling on the crab, or the crab on the codling is too great a cross. J. Howden. 
Mode of Taking Impressions of Leaves. —For the information of your 
correspondent H. C. page 90, I send you an account of taking impressions of 
leaves on paper. I can answer for its efficacy. Take a sheet of paper which 
has been previously oiled, and move it slowly over the frame of a lamp or 
candle until it is uniformly black all over. On this lay flat the leaf of w'hich 
the impression is desired, with the underside downwards, cover it with a piece of 
clean paper, and in doing so, be careful to adjust the leaf, that it shall not be 
folded. Then hold the paper firm with one hand, and with the other gently 
rub in every direction over the leaf. Its veins will now be charged with black, 
lay it on w'hatever is intended to receive the impression, and again place clean 
paper over it, repeat the gentle friction, and you will have the desired fac-simile.

Where can I buy the Skinless Oats ?—In one of your late numbers, 
you speak very highly of the Skinless Oats lately introduced into this country, 
and consequently as yet very scarce. I should be obliged, if you would inform 
the public in your next Register , where they can be purchased, and at what price 
they may be obtained. If I can procure but one pint of them, and can have an 
equal, or one half of the increase that I have got this summer from three grains 
of wdieat, I shall soon have enough to supply the parish. In the spring I found 
some ears of wheat growing in my garden near the wall trees; their presence in
