Glass whale-ol! lamps with enclosed reservoirs and tight-fitting burners were an American 

 innovation. The earliest (like that shown at far right) were simple blown-glass devices. 

 After the mechanical pressing of glass was introduced in 1826, lamps were made with 

 blown fonts and pressed bases. Second lamp front rieht was made at Sandwich, Mass., 

 about 1830; the others are somewhat later.
