other words, the Kindle party was not sufficiently interested to collect or a least to report upon the algae of the region. One must, therefore, wonder
if the alleged absence of them from Lake Melville is based upon an energetic and intelligent effort to find them ; for, in view of the demonstrated presence
near the head of the Lake of the maritime flowering plants, it is quite unbelievable that the marine algae do not likewise extend to the head of Lake Melville.
The only extensive report which I know on the marine algae of the lower St. Lawrence is that of Kemp,1 but it is surely a most significant fact that the truly marine species extend in the St. Lawrence up to the limit of the strictly maritime flowering plants. Thus at Murray Bay, near the inner limit of the maritime flowering plants, such genera of algae are found
as Cladophora, Enteromorpha, Chorda, Chordarie, Ectocarpus, Delesseria, Phyllophora, Polysiphonia, Rhodomela, etc., etc., and near the inner limits of Poa eminens, Stellaria crassifolia and Senecio pseudo-arnica such genera of marine algae as Laminaria and Agarum occur.
It should be perfectly evident, then, that the marine algae extend quite as far as the strictly maritime flowering plants ; and as these same species of flowering plants reach nearly to the head of Lake Melville, it is only reasonable to believe that the marine algae must also be present in the waters near the head of the Lake.

It is shown that Dr. Kindle has not hesitated to guess at the identities of plants, and that his guesses are too often erroneous.
It is shown that the statements of habitat in the Kindle report are so largely at variance with the statements by the most accurate Canadian and American botanists that no reliance can be placed upon them. Of the three species specially emphasized by him as occurring only from the Narrows eastward and, therefore, to his mind “ salt-loving ” plants, two are most emphatically not plants of saline habitats, and the third, instead of stopping at the Narrows, actually extends to the head of Lake Melville.
It is demonstrated, largely on evidence collected by Dr. Kindle's party, that several of the maritime plants known from the Hamilton Inlet region extend westward nearly to the head of Lake Melville. These plants elsewhere in Eastern America occur only on the ocean-margin or about the Gulf of St. Lawrence or the lower River St. Lawrence. Their occurrence at the head of Lake Melville is evidence that Lake Melville is an arm of the sea.
It is shown that in other regions, notably the lower St. Lawrence, the distribution of the strictly maritime plants, which we positively know from near the head of Lake Melville closely coincides with the distribution of the marine algae. It is, consequently, impossible to avoid the conclusion that Dr. Kindle's contention, that marine algae do not occur far up Lake Melville, is based on a preconception rather than upon a vigorous attempt to find the algae there.
