insignificant dimensions. I have myself taken tbe measurements 

 in the spring of the present year, with the tape and with the 

 quadrant, so that I can speak with some certainty on the point. 

 The sloping side is 270 feet ; the circumference of the bottom 1632 

 feet ; the diameter of the base 544 feet ; the diameter of the top 

 40 feet ; the perpendicular height 130 feet ; and the angle of ele- 

 vation 27|° : so that with an altitude and circumference of base 

 nearly identical with those of Silbury, it is only the inferior size of 

 the platform on the top and the consequently lower angle of 

 inclination, which bring its cubical contents below those of our 

 "Wiltshire mound. But not to linger over this modern colossus 

 of graves, interesting though it is to compare it with our ancient 

 giant among tumuli ; 1 now bring my somewhat lengthy paper 

 to a close, leaving it to the Members of the Wiltshire Archaeological 

 and Natural History Society to form their own opinions on the 

 subject : only I would bespeak the respect of all Wiltshiremen 

 for Silbury, which deserves our reverence from its antiquity, 

 our admiration from its size, and our awe from the mystery which 

 envelopes it.
