FLOWERING PLANTS. 

 Growth of an Oak. — When looking at the grave of my 

 grandfather (a Halifax man) at Tarporley, Cheshire, a short 

 time ago, I found that an Oak tree planted near the grave by 

 mv father and grandfather in 1833, had increased in diameter 

 since then 17 inches. It is now 543'4 inches in circumference 

 three feet above the ground. — Harper Gavthorpe, Barrow-in-
