THE WHEAT CULTURIST. 



" But procure seed from Canada, Sweden, or anymore 

 northern locality, where the temperature in the average 

 is colder, and the time of first growing later in the 

 spring, Knd harvest still later, in consequence of the 

 lower average of summer heat,' and the more time 

 needed to supply the heat required; take seed wheat 

 from such a situation to one where the growing season 

 commences earlier by reason of the requisite heat being- 

 earlier present, and it will not only commence its growth 

 as much earlier as the germinating degree of heat ear- 

 lier surrounds it, but will ripen much earlier generally, 

 as the average heat is higher by reason of having been 

 subject to the whole amount of the great thermal ele- 

 ment necessary to its maturity in a shorter or less period 

 of time. ! Thus, on this question, theory and facts ap- 

 pear to adjust themselves consistently together ; and our 

 decided conclusion is, that from farther north is the di- 

 rection seed wheat or corn, or in fact any cereal, should 

 be r procured, if the object be to secure earlier maturity 

 in the -resulting product. Cereals that ripen early far 

 north, will naturally and with general certainty mature 

 earlier when cultivated considerably farther south."

No FACTS TO PKOVE IT. 



Old wheat-growers will contend earnestly, that facts 

 are against this theory. If they are, I have not had the 

 good. fortune to meet those facts. If it can be shown 

 by well-conducted experiments that seed wheat should 

 be procured in a southern latitude, then we will believe 

 it. But, in order to establish such an assertion, excel- 

 lent seed must be obtained in every instance, and the 

 test made fairly, for several successive seasons.
