express their resentment, in conformity with the popular 

 feeling against the .oppressive measures of the British

 took care should be strictly kept even by those who

 services of Thompson less necessary to him. In the 

 mean while the boy, more engaged, we must venture to 

 say, in his scientific experimenting than in the cause of 

 demonstrative patriotism, came very near to losing his 

 eyesight, if not also his life, by an alarming accident. 

 He had undertaken to prepare some fireworks for use 

 in a public jubilation over the news of the repeal of the 

 Stamp Act. While grinding his materials in a mortar, 

 a terrific explosion, probably caused by some grains of 

 sand in the compound, involved his head, hands, and 

 breast in its fearful consequences. He suffered a long 

 confinement and much pain, and was regarded as very 

 fortunate in escaping permanent injury. 



The following correspondence shows that young 

 Thompson was at home, probably in a state of con- 

 valescence, at the time of its date :
