Dolgelli. Next morning Byers and I had a scramble 

 till 6 P.M., when I got a return car as far as the cross- 

 roads near Ffestiniog. I slept at Ffestiniog, and next 

 morning walked up Cwm Orthin and over Cynicht to 

 Cwm Gwynant, near Beddgelert. I had never been 

 on Cynicht before, and learned a few things for the 

 Memoir. I then walked to the top of the Pass, where 

 I found a return car and reached Llanberis at

 necessarily into more current or running English. 

 This will be submitted to you in good time. I have

 given me a single note about the latter.' 



To the same correspondent, on the i3th August, he 

 sends thanks for congratulations on the birth of a son 

 on the 6th of that month, and adds : ' I hope to be at 

 Llanfairynghornwy for a day by Thursday at latest en
