 Norfolk, stretching for miles their sandy wastes, with here 

 and there a stunted growth to mark the effort of nature to 

 reckim them, have been transformed into broad fields of life- 

 sustaining crops ; and the fens of Lincolnshire, reeking with 

 malaria, have been changed into the granary of England. 

 Thirty years ago and the Whitworth guns were the terror 

 of the world, but the canny Scotchman, loading them with 

 canister filled with seeds, aimed them at the beetling crags, 

 which, lifting their towering heads far into the empyrean, 

 defied ascent by man, and lo ! the shells, bursting amid the 

 clouds, scattered the seeds far and wide, and to-day his 

 grace the duke of Athol looks with pride upon the wooded 

 heights of Craigybarnes.
