LLANBERIS, izth July 1849. 



MY DEAR TALBOT At length since Monday last 

 we have had fine weather here, and I have worked so 

 hard that I am quite fatigued to-day, and stay at home 

 to despatch some maps, and knock off the arrears of 

 correspondence. I think the ground I am at present at

 entering into conversation, we walked down together. 

 It lightened the way a bit. Dined at nine.
