state presents a noble area for the solution of problems 

 connected with the varied meteorology of temperate re- 

 gions. The directions for this extensive undertaking 

 were prepared by Mr. De Witt. 



Among the interesting results already obtained, direct- 

 ly applicable to our numerous works of internal improve- 

 ment, is the approximation to the actual quantity of rain 

 and snow that fall in various situations, and the effect of 

 altitude or of clearing forests, on this. Among the high- 

 er scientific results, are the deductions to be hereafter 

 made from the simultaneous appearance of the Aurora 

 Borealis in the northern latitudes of Europe, and in this 

 state. Observers in Great Britain are already noticing, 

 with great solicitude, this striking occurrence. 



To another subject, Mr. De Witt devoted equal atten- 

 tion. This was the variation of the magnetic needle. 

 In a report to the Board of Regents, it was stated, "that 

 it was very desirable that observations should be annu- 

 ally made on this, in as much as the boundaries of lands 

 are usually described according to the courses indicated 

 by the needle, and there are no rules by which its varia- 

 tions can be ascertained, for any interval of time, ac- 

 cording to which such bounds may be retraced where the 

 land-marks have been obliterated." As, however, the 

 Regents could not make the duty of observing impera- 

 tive, it was resolved that they would recommend the 

 same, and for this purpose a series of directions were 

 drawn up by Mr. De Witt. Several of the institutions 

 have complied with the request, and there is no doubt, 

 but that as they acquire proper instruments, all will at- 

 tend to it. 



In connexion with the subject of education, I must
