land and ranges from Central Europe to northeastern Asia, ['hints 

 Hollandica variety superba Rehdr. is a very graceful elm, and a very 

 large example grows on the edge of the lawn in front of the Ell- 

 wanger & Barry office on Mt. Hope Avenue. The circumference 

 is 18.35 feet, and the height is 70 feet. It is said to have been 

 planted not over sixty years since. This is an extraordinary girth for 

 a tree to attain in that time. At five feet from the ground it breaks 

 into seven large boles, and has an enormous spread. 



.There are numerous splendid examples of the American Elm, 

 Ulmus Americana Linn., in the vicinity of Rochester, and throughout 

 the Genesee Valley. We will call attention to four individuals that 

 are somewhat notable. In the grove in Genesee Valley Park there 

 is a very large American Elm with a wide spreading head, and in 

 perfect health. The circumference is 16.8 feet, and the height is 

 perhaps 100 feet. A good example of the vase form of the Ameri- 

 can Elm grows on the Latta Road about one mile west of Charlotte. 

 The girth is 12.3 feet, and the height is 90 feet. A fine individual 

 of the umbrella type of American Elm grows on the state highway 

 about two miles east of the village of Avon. The circumference is 

 16.2 feet, and the estimated height is 110 feet. On the farm of 

 Mr. W. G. Markham, two miles north of Avon there is now the 

 lingering remnant of the "Markham Elm". This was a landmark 

 in its day. All that remains of the tree is a large limb from the 

 north side of the base and this is supported by a stout brace. This 

 elm was first seen and attracted the attention in 1764 of William 

 Markham who was a soldier in the colonial army and the great 

 grandfather of the present William G. Markham. It was at that 

 time a tree of extraordinary size. It is stated that during this known 

 period of its history in four Markham generations no perceptible 

 change was observed in its size. In the spring of 1893 the north 

 side of the tree was blown down. Mr. Markham had this sawed 

 across, and he counted three hundred and seventy-five rings. From 

 the portion beyond which he counted, there was a large decayed area 

 towards the center of the tree which he estimated proportionately, 

 and he felt confident this elm had lived about six hundred years. 

 The trunk was 45 feet in circumference three feet above the base, 

 and at noon the shade of the branches extended over one acre. From
