pair of horses which, as they transported loads of stone 

 from place to place, were lean and dull. Mr. Maclure was 

 at that time in his meridian. Being a teetotaller, drinking 

 nothing but water and requiring only a moderate quantity 

 of the most common articles of food, his health was perfect, 

 and his frame robust and vigorous, as his temperance was 

 associated with much travelling and with mountain excur-

 forty years with an immense expenditure of money and an 

 unselfish devotion of time and effort without any personal 

 advantage, bore every mark of benevolence and good-will, 

 not only to his adopted country, but to mankind. Mr. 

 Maclure was a punctual correspondent. For about twenty 

 years, we exchanged letters, rarely, I believe, omitting a 

 year. His brother, who was his executor, kindly returned
