MEMOIR OF DANIEL TREADWELL. 



•Ml 



The following is a summary of the guns manufactured by Mr. Tread well : 



"Of the guns with a lining of steel, the wrought-iron bars being wound upon a previously 

 formed steel ring, eight were six-pounders of the common United States brou • pattern, and 

 eleven were thirty-two-pounders of about eighty inches' length of bore, and eighteen hundred 



pounds' weight. Six of the six-pounders and four of the thirty-two-pounders were made for the 

 United States. They have all been subjected to the most severe tests. One of Hie six- 

 poundcrs has borne 1,560 discharges, beginning with service chargi i and ending with ten 

 charges of six pounds of powder and seven shot, without essential injury. It required to 

 destroy one of the thirty-two-pounders a succession of charges ending with fourteen poundi 

 of powder and five shot, although the weight of the gun was but sixty times the weight of 

 the proper shot." 



Besides these, several guns were made on Mr. Treadwell's own account. 



The buildings in Brighton were never occupied for the purpose intended, nor 

 for any purpose, except for a short time in 1848 as barracks for the volunteer 

 soldiers of Massachusetts returning from the Mexican War. The machinery and 

 tools, together with the buildings, were sold in 1855, the land in 1864, and the
