 temperature was some 10"^ liigherin one place than

 10 and 15 days in tiie maturity of the wheat in 

 favor of the higher mean temperature. {See table.)

This table proves all that "we have contended for 

 — that a reduction of the zero point and an increase 

 of the jnean temperature will hasten the maturity 

 of plants. We readily admit that the increase and 

 diminution of the days, according to the table, are 

 not always in the same exact ratio with the increase 

 and diminution of the zero point and the mean 

 temperature, but the slight variation may be readily 

 accounted .for, as either resulting from sowing 

 ditferent kinds of wheat, or from the dryness or 

 dampness of the season. The same variations are 

 not so palpable in corn as in wheat and barley. 



AYe deny the assertion of your correspondent, 

 that apples and pears hang longer on the trees here 

 than they do at the nortli. This assertion is dis- 

 proved by a single comparison of catalogues, which 

 show that most of the apples and pears of the same 

 kind ripen from four to six weeks sooner here than 

 they do at the north. Now, as a matter of fact, do 

 trees south vegetate that much sooner than they do 

 at the north ? We would suppose there was no 

 such difference. Then liow are we to account for 

 this difference in maturity? Simply by the differ- 

 ence in the zero point and mean temperature* We 



* If our mean temperature is less than it is at the north, then 

 apples and pears will of course remain longer on the trees here 

 than at the north, not otherwise. 



are now eating fine Secl'el and Doyenne Sieulle 

 pears. The latter will not be ripe before October 

 at the north. Then, if wheat, fruits, etc., taken 

 from the south will mature earlier at the nortl;, ;is 

 intimated by J. B. C, why can you not cultivate 

 the Lagrange, Smock Free and Ward's Late peaches, 

 which ripen here in Se])tember and October? 

 Simply because the season is too short for them at 

 the north, and they will not ripen in September 

 and October there, a.s is proved by the catalogue of 

 1858 of Messrs. Ellwanger & Barry, of Rochester, 

 N. Y. Consequently, removing them north, so tiir 

 from hastening their maturity, only procrastiimtes it 

 The doctrine we are attempting to inculcate i^ 

 not new ; it is as old as the time of Columella, 

 where it will be found more than once referred to. 

 But it is impossible to discuss it in an article ot 

 suitable length for your paper. Consequently, we 

 have not done anything like justice to it, important 

 as the subject really is. But before we close, we 

 must make one remark as to the experiment of 

 your correspondent, because he does not inform us 

 whether the wheat experimented with was the same 

 kind or not, nor whether it was planted at the 

 same time or not, nor whether it was planted upon 

 the same or a difierent kind of land. Until this is 

 done, the experiment is really worthless, for, from 

 the time of the same old author down, we have 

 been told and know by experience that different 

 kinds of wheat require different lengths of time to 

 mature. _ Consequently, all experiments should be 

 made with the same kind of wheat, planted on the 

 same kind of land and sown at the same time. 

 When all this is honestly done, this theory will 

 prove to be a stubborn fact.
