growth, and less vigorous. Almost identically like the red cedar, 

 which in the Middle and Southern States is a large and vigorous 

 tree, gradually becomes smaller and smaller toward the north 

 until it disappears as a low scrubby specimen. 



Those trees referred to appear also more sparsely toward 

 the he'ad of the lake. Reference is here made to the Sassafras, 

 the Tulip Tree, Nyssa multiflora and the Beech. Tulip Trees 

 introduced into the more fertile Morain are winter-killed, except 

 when planted under very favorable conditions, and even then are 

 subject to being killed by frost at any time. Sassafras comes 

 under the same class. 



That the two trees in the Waukegan Cemetery survived the 

 winter of 1898, and the one on the grounds of Mr. Douglas was 

 killed, was due to the fact that this killing freeze was followed 

 by severe rains. The Douglas tree stood on level ground, and 

 consequently had a wet foot. Those in the Waukegan Ceme- 

 tery were planted near the gutter of a roadway considerably 

 lower than the point at which the trees stood, and the soil ab- 

 sorbed but little of the rain that fell. It is also evident that 

 where the trees have been planted closer to the shores of Lake 

 Michigan, and thereby subjected to the lake and the moist-bring- 

 ing lake fogs, they survive better than those farther inland. A 

 study of the natural vegetation within a few hundred feet of 

 the shores of Lake Michigan will tell the story. 



The Beech (Fagus ferruginea), found in groves twenty or 

 more miles north of the Wisconsin State line, has been dis- 

 tributed toward the head of Lake Michigan within a short dis- 

 tance of Chicago. The two groups, one west of Waukegan, 

 and one at Highland Park, twenty-four miles north of Chicago, 

 are supposed to be native.' The other tree referred to is found 

 in a private garden, and smaller specimens are found in gardens 

 farther toward the head of the lake. 



The late Thomas Douglas, who was born in Waukegan 

 when Indians still existed within a short distance of the city, 

 at that time a village, was of the opinion that the Beeches at 

 Highland Park had been brought there by the pigeons which 

 at that time, and still later, infested these forests by the millions. 

 The pigeons were fond of beech-nuts, and it is not at all im-
