Garrion Tower and Mauldslie Castle, 30th May, 1903 

 (Conductor, Mr. John Renwick). — The forenoon was showery, and 

 only eleven members and friends turned up. A veiy heavy 

 shower was experienced at Garrion Tower, but the rest of the 

 day was dry and warm. The party went by rail to Ayr Road 

 Station, a place which derives its name from the fact that it is 

 on the road from Edinburgh to Ayr via Strathaven. This road 

 was made about 1817, when the bridge over the Clyde at 

 Garrion was opened. Before that time there was no bridge 

 over the Clyde between Lanark and Hamilton, a distance of 

 fourteen miles. 



The name of the station has recently been altered to Dalserf, 

 that of the parish in which it is situated. 



The valley of the Clyde is here very deep; the station, about 

 seven furlongs in a straight line from the river, and not near 

 the summit, is about 250 feet above the stream. 



This was the Society's first visit to Garrion Tower, but three 

 members had visited it in 1900, and had measured four fine 

 trees, all of them worthy of a place in the list published in the 

 British Association Handbook, 1901. The figures relating to 

 these and to others measured on this occasion are: —
