Almost ten years later, after Burn's death in 1796, Murray began an ambitious scheme of planting that would eventually include 120,000 Larch and Scots Pine. The Duke was of the opinion that the planting should be both pleasing to the eye and profitable. He was eventually to become known as "Planter John", planting over 15 million trees throughout his estates during his lifetime. At the Falls of Bruar he also laid out the path that is still in use today, constructed the two bridges as viewpoints over the falls, and built a large number of huts and shelters. The huts were disliked by some visitors, and eventually fell into disrepair: only the partial remains of one stone hut can still be seen. William Wordsworth objected to the neatness of the paths when he visited in 1815, but the harsh lines of these have mellowed over the years. During the Victorian period many Rhododendron were planted to enhance the landscape.
