The President remarked that persons engaged in testing the properties of plants adapted for feeding stock in this colony were engaged in work beneficial to the whole community, and therefore he welcomed the paper now contributed by Dr. Curl. At the time he observed with regret that no mention was made of the condition under which Dr. Curl's experiments were performed, such as quality of soil, time requisite for the maturation of the plant, mode in which fed off, and other elements necessary in order to form a correct opinion of the value of each kind. Not more than two or three of the species mentioned in the paper were adapted for mixed pasturage, although most would doubtless be found of value as fodder. He remarked that Agrostis solandri, recommended by Dr. Curl, was a collective species, chiefly consisting of two New Zealand grasses, Agrostis æmula and A. billardieri. Poa aquatica was merely a synonym for Glyceria aquatica although the two are given by the author as distinct plants. Glyceria fluitans was a grass of undoubted value, as was proved by the condition of horses and cattle feeding upon it, wherever naturalized in the colony. Referring to Dr. Curl's use of the term “acclimatized,” he stated that a fallacy was involved in the popular acceptation of the term, as there was no evidence to show that plants or animals possessed the power of gradual adaptation to peculiarities of climate or soil other than those for which they were originally fitted. This was generally recognized by scientific men, who used the term naturalized instead of acclimatized.

8. “On a further Occurrence of the Australian Tree Swallow (Hylochelidon nigricans) in New Zealand,” by Walter L. Buller, C. M. G., D. Sc. (Transactions, p. 360.)

The author remarked on the extraordinary fact of such a bird performing a journey on the wing of upwards of a thousand miles without a break or rest.

Dr. Hector wished to be informed whether this bird was gregarious in its native country, and whether it had come over singly or in flocks?

Mr. Martin Chapman gave some interesting particulars of the breeding habits of the tree swallow, as observed by him in Australia, where it is not gregarious like the sparrow. He advocated its introduction and naturalization in this country.

Dr. Buller stated that a flight of these swallows had been seen at Wakapuaka, near Nelson, in 1856, when specimens were obtained by Mr. Lee, one of which is now in the Otago Museum.

The President said that he believed the bird was of more frequent occurrence in New Zealand than was commonly supposed, and he mentioned the circumstance of a pair being shot at Auckland some time ago. With regard to the proposed troposed introduction of this
