IMPERIAL UNITY [PART VIII in their opinion, they had not been in a position to make any such study of the question as to justify reliance on their judgement. The discussions on defence matters were, of course, confi- dential, but there was, as a matter of fact, nothing of any substantial importance to deal with so far as military defence was concerned, for the Conference of 1909 had settled in principle the lines on which Imperial co-operation in defence are to proceed, and therefore nothing more remained to be done on this occasion but to affirm the principles already accepted, and to report the progress already made in carrying out the resolutions of 1909. As regards naval defence much was done to render explicit the agreement arrived at in 1909.21 As regards commercial treaties a definite step was taken in the decision to attempt to secure the right of separate withdrawal from old treaties for the Dominions. But this is merely a carrying out of an old principle, nor does the Imperial Government seem to have conceded the right to any Dominion to conclude a treaty with a foreign country in which it would discriminate against the United Kinedom.2 1558 ‘ The change of government in Canada is expected to result in the reference to the people of the question of Canadian participation in naval defence ; see Mr. Pelletier, Canadian Gazette, lviii. 188; Mr. Monk, House of Commons, Nov. 23. 1911.

Negotiations for withdrawal had already been attempted with Austria and [taly at the wish of the Commonwealth, but unsuccessfully ; see Cd. 5745, p. 337. The negotiations have been begun, and a new treaty made with Bolivia. For a list of the treaties, see p. 1153, to which as affecting all or some Dominions fall to be added that of 1826 with France, that of 1883 with Italy, that with Morocco of 1856, that of 1888 with Mexico, and possibly one or two others ; cf.
