His reaching New Mexico seems to be the turning-point for his long and 

 perilous wanderings ; he was well treated by the Indians, and soon heard rumors 

 of the Spaniards which led him to turn his steps south, and in 1536 to reach the 

 goal of his hopes, with his companions, the City of Mexico; whence they em- 

 barked for Spain, which they gained ten years after the fated expedition had left 

 it to conquer, as they fondly expected, a new country across the seas. 



But Alvah Nufiez Cabeza de Vaca had won one title, which as she grows 

 in wealth and fame will be one for history to value : i. e. The first white man to

There is no problem likely to be presented to the statesmanship of our 

 ■country in the next century, that requires as much deep analyzing wisdom as 

 the one that demands homes and employment for the young men and women 

 who are forming so vast a proportion of our population. To see this subject as 

 it advances and increases in importance and magnitude we must look into the 

 past and present, and from them anticipate the future. 



I will give the population of the United States in 1780 and at the various 

 decades since, with the per cent of increase in each period of ten years :

In the century past the population has increased at an average of 33 per 

 cent compounded every decade. In that century, too, that population had hard- 

 ships and impediments to surmount that may not impede progress or delay the 

 increase of the next. In that century, the active and inventive mind of the 

 American mechanics and scientists has invented, and constructed, and patented 

 312,000 improvements on the old order of things, that the burthens and labors of
