August—are within 2° of being as warm аз these months are оп the 
average at Chiswick, 500 miles farther south. 
* During the short nights in the far north, the earth does not be- 
come so much cooled as in more southern latitudes; vegetation there- 
fore continues night and day without interruption, in other words, a 
lower and continuous degree of warmth produces the same effect in 
Norway that а higher temperature, interrupted by proportionably colder 
nights, produces in countries lying more to the south. Corn and other 
plants will ripen under a much lower temperature, and in a much 
shorter time, in Norway than in countries farther south." 
Four-rowed Barley was exhibited from the model farm of Ladegaard- 
soen, Christiania. It was sown on the 21st of May; gérminated the 
29th of that month; eared the 12th of July; flowered the 20th of 
July; and was harvested the 24th of August. Weight, 50 lbs. 6 oz. 
per bushel. 
‘Dr, Schübeler remarks that “ Corn, or other seeds, brought from a 
southern to a northern climate require, at first, a longer time to ripen 
than the same species which have been cultivated there for some time, 
but after the lapse of two or three years, the plants obtained from 
foreign seeds generally acquire the same ripening peculiarities as their 
corresponding species, which have been cultivated for a longer time in 
the country." | 
From this it may be inferred, that if a certain variety of early pea, 
for example, were brought from a cold situation to a warm, it would 
ripen, or be fit for use, earlier than that same variety grown from seed 
matured in a warmer locality. In the case of early peas, all are 
anxious to obtain the very earliest known sort; and the knowledge of 
ny means by which that could be produced, even two or three days 
earlier, would be considered important, whether for a gentleman’s table, 
or for the market. The experiment is worth trying. Some early pea 
might be grown and ripened for seed on a north border, and some of 
the same sort on a south one; and let both be sown under equal cir- 
cumstances on the south border. If the advantage is in favour of the 
cool grown seed, a useful principle would be established. 
Change of seed from а cold to а warm climate, and vice versá, has 
an effect, it appears, not only as regards earliness, but also with respect 
to bulk and weight. Dr. Schübeler has observed that “ So long аз а 
plant is not cultivated farther northward than it is able to attain its 
full development, the seed increases in size and weight for the first 
two or three years, the nearer it approaches this limit; but it dimin- 
ishes in like manner, if cultivated several degrees farther south. The 
greater the difference in latitude between the respective places, the 
more marked is this difference.” 
According to this, an improvement in bulk and weight of corn would 
result from employing seed for a northern locality that had been 
ripened in a southern ; and for northern slopes of farms, seed that had 
been produced on their south-lying aspects.
