THE BELL ROCK LIGHTHOUSE. 



PART VII. 



the work having proceeded satisfactorily, the whole was 

 completed by the end of 1810, and the light was regu- 

 larly exhibited after the 1st of February, 1811. When 

 finished, the tower was 10 feet higher than the original 



design, being 95J feet to the top 

 of the cornice, and 127 feet to the 

 top of the lantern. The additional 

 height to which Mr. Rennie had 

 thought it necessary to carry the 

 lighthouse during its construction 

 had the effect of raising the total 

 cost to 6 1,3 3 II. ; but he believed 

 the increased outlay would be 

 fully justified by the greater secu- 

 rity given to the building, and its 

 increased efficiency for the purpose 

 for which it was intended. 



Notwithstanding the facts which 

 we have stated, showing that Mr. 

 Rennie acted throughout as the 

 chief engineer of the lighthouse 

 that he furnished the design, 

 arranged the details 

 of the building, settled 

 the kind of materials 

 to be used down even 

 to the mode of mixing 

 the mortar, and from 

 time to time made va- 

 rious alterations and modifications in the plans of the work 

 during its progress, with the sanction of the Commission-^ 

 ers his name has not usually been identified with the 

 erection of this structure ; the credit having been almost 

 exclusively given to Mr. Robert Stevenson, the resident 

 engineer, arising, no doubt, from the circumstance of 

 Mr. Rennie being in a great measure ignored in the
