FOURTH SHOW AT GLASGOW, 1 844. 285 



conversation turned on the best means of making the 

 practical farmer acquainted with the recent discoveries in 

 science, and enabling him to apply these to the cultivation 

 of his own farms. Professor Johnston spoke hopefully of 

 the results of his labours, remarking, that wherever he went, 

 he had 200 or 300 farmers attending him, who seemed to 

 drink in with avidity the information supplied. At the 

 same meeting, Sir Chas. Fergusson referred to the circum- 

 stance that in Ayrshire a few gentlemen had purchased a 

 vessel, and sent it out for guano, as an illustration of the 

 new era that had opened up in the history of agriculture.
