tlie land and the husbandman, and it is a fact that needs no further proving. 
Now, if we are to put any reliance in that indefatigable agricultural chemist, 
Liebig, all plants absorb from the atmosphere, and decompose a large amount 
of carbonic acid by the leaves, (and this theorizing becomes fact in practice ;) 
if so, it is evident that those of large and succulent foliage and low growth 
will draw freely of this gas, and not unlikely but they will deposit a super- 
abundant portion in the ground beneath, from the downward current of the 
sap ; consequently, it is reasonable to suppose that, if spinage, lettuce, &c., 
precede peas, Lima beans, corn, &c., the latter will be benefited by the pre- 
vious action of the former. Our own experience testifies to the truth of 
such presumption, and may be an excuse for the recommendation. 
With regard to the quantity of produce on a given space, there is a great 
difference, according as a skillful or negligent succession is kept up ; indeed, 
so great is this, that one man will only clear one hundred dollars per acre, 
while another can more than quadruple the amount at market prices, and 
simply by the way in which the different crops are made to succeed each 
other, — one is contented to take one. per year, while the other obtains two, 
and in some instancs even three. Perhaps an example or two may help to 
ilustrate how this latter may be accomplished. Suppose a plot has to be 
sowed with early peas ; at the time of sowing, a row of radishes, or spring 
spinage, may be drilled in midway between the peas ; these will be off before 
the latter are far advanced ; and when the peas are up, a crop of beets for 
fall and winter use, may be put in the same place. The general successions 
of peas may be accompanied by early lettuce in the same way, and the 
ground afterwards prepared for celery, which may be planted from the seed 
bed before the pea haulm is removed, and so on. A little close calculation 
of this nature will show many more instances of a similar character, and 
enable the cultivator to make the most of a limited space. 
There is always a dearth of good vegetables in the earlier part of the 
season ; and an advantage is to be gained on this account, by choosing the 
earliest varieties, and forwarding some of the most necessary crops. Some 
peas, for instance, are ready a week or ten days before others, and these may 
be hurried on, by sowing them three or four weeks before those on the open 
ground, in shallow boxes, or on pieces of grass turf, placed in a close cold 
frame, or late grapery, and afterwards planted out in a warm, sheltered situa- 
tion, when the weather becomes favorable. The best for first early that we 
have "yet tried are, Warner's Early Conqueror, Warner's Early Emperor, 
and Smith's Early. For general crop there is none better than the Cham- 
pion of England, which is a good bearer and unsurpassed in flavor. Sweet
