tulip poplar, Liriodendron tulipifera" (p. 361). The southern 

 limit of Piniis banksiana in Maine is Penobscot Bay and that of 

 Picea alba, Casco Bay, points that can be located in "The northern 

 portion of Maine" only by one woefully careless in his statements. 

 If the sentence quoted above be taken literally, the northern limits 

 of Liriodendron should be found in the northern portions of the 

 three states mentioned. According to Sargent's, and other tree 

 manuals, the northern limits of the Tulip, in England, may be ap- 

 proximately determined by drawing a line from the northeast 

 corner of Rhode Island to the southwest corner of Vermont. If 

 this were the southern limit of the New Brunswick Area, then 

 the forests of White Oak, Black Oak, Chestnut and the hickories 

 of southeastern Vermont and eastern Massachusetts would be 

 placed in the same phytogeographical entity with those of New 

 Brunswick where none of these species occur! If the southern 

 limit of the Banksian Pine were the boundary, then the greater 

 portion of the Green Mountains and the White Mountains would 

 be excluded from the New Brunswick Area, a thing which the 

 author did not do, as shown by the parenthesis, "including their 

 mountain ranges" in the first sentence of this paragraph. 



If, as Harshberger states, the forests of New Brunswick and 

 Nova Scotia are identical, he may give an erroneous impression 

 of both, but he surely does for those of Nova Scotia (p. 362). The 

 mixed forest is the prevailing type, but Sugar Maple and Paper 

 Birch are not the dominant members. Taking the Province as a 

 whole, the Beech is more prevalent than the Sugar Maple and the 

 Yellow Birch is more abundant than the Paper Birch. And, more- 

 over, the conifers (Red Spruce, Balsam and Hemlock) and not 

 the hardwoods are the dominant members of the mixed type. 

 The author must have been only looking at the peat bogs and their 

 low separating sandy ridges when he got the idea that Black 

 Spruce, White Pine and Larch were the controlling members of 

 the forest in Minas Basin (p. 364). The only place specifically 

 mentioned in Minas Basin is Grand Pre, and this is unfortunate 

 from the standpoint of forest description for, as the name sug- 

 gests, the place is a prairie. The forests in sight, however, on the 

 tops of the adjacent mountain ranges, are of the mixed type with 

 Red Spruce and Balsam predominating. The description of 

 other places mentioned in Nova Scotia are nearly as far from
