On arrival at Pollok the party was met by Mr J. Campbell 
Murray, factor on the estate, and Mr J. Boyd, the forester. 
The nursery at Cowglen was first inspected. This was found 
to be well stocked with broad-leaved trees of various kinds, 
and with seedling conifers for the proprietors Highland estate 
of Corrour, Inverness-shire. From the South Lodge the party 
drove through the fine park stretching along both sides of the 
river Cart. The old trees are in a dying state, but it was noted 
that clumps of young ones had been planted to take their 
place. A visit was also paid to the creosoting-tank. This is 
constructed on what is known as the “open” plan, ze., the tank 
consists of an open boiler in which the timber and creosote are 
placed, and the temperature of the latter raised to a little over 
212. Fahrenheit, at which it is kept for forty-eight hours or 
thereby. Many samples of creosoted timber, both broad-leaved 
(oak, ash, elm, beech, sycamore) and coniferous, were shown 
to illustrate the effectiveness of the process, and Mr Boyd 
had cross-sections of larch and Scots pine prepared to show 
how the creosote did not penetrate the heart-wood, but that 
the sap-wood was completely impregnated with it. The boiler, 
which is egg-ended, is 25 feet long by 5 feet in diameter, 
and can therefore take in a large quantity of material at a 
time. The party then proceeded to Pollok House, where they 
were entertained to luncheon by Sir John Stirling-Maxwell. 
Mr Murray, who presided, on behalf of Sir John, welcomed
