Various other lines were from time to time claimed by Great Britain, each one extending the frontier of British Guiana farther and farther to the west. The British Colonial Office List, a government publication, in the issue for 1885, put the area of British Guiana at about 76,000 square miles. In the issue of the same list for 1886 the same statement occurs in reference to British Guiana with the change of area to "about 109,000 square miles." Here was a gain of 33,000 square miles without any statement whatever in explanation of how this additional territory had been acquired.

After the failure of repeated efforts on the part of Venezuela to secure an adjustment with England, she finally came to the conclusion in 1882 that the only course open to her was arbitration of the controversy. She persistently urged arbitration, but Great Britain refused to submit to arbitration any but a comparatively small part of the territory in dispute. In 1887 Venezuela suspended diplomatic relations with Great Britain, protesting "before her British majesty's government, before all civilized nations, and before the world in general, against the acts of spoliation committed to her detriment by the government of Great Britain, which she at no time and on no account will recognize as capable of altering in the least the rights which she has inherited from Spain and respecting which she will ever be willing to submit to the decision of a third power."

After repeated efforts to promote the reëstablishment of diplomatic relations between Venezuela and Great Britain and after repeated offers of its good offices for the purpose of bringing about an adjustment of the controversy, President Cleveland finally determined to intervene in a more positive manner with a view to forcing, if need be, a settlement of the controversy. This resolution on the part of the American executive, with a full statement of its views on the general principles involved in the dispute, was forwarded to Mr. Bayard for transmission to the British government in Mr. Olney's dispatch of July 20, 1895.[244] After reviewing the history of the controversy Mr. Olney stated in the following concise form what he considered the important features of the situation as it then existed:

1. The title to territory of indefinite but confessedly very large extent is in dispute between Great Britain on the one hand and the South American republic of Venezuela on the other.

2. The disparity in the strength of the claimants is such that Venezuela can hope to establish her claim only through peaceful methods—through an agreement with her adversary either upon the subject itself or upon an arbitration.

3. The controversy, with varying claims on the part of Great Britain, has existed for more than half a century, during which period many earnest and persistent efforts of Venezuela to establish a boundary by agreement have proved unsuccessful.

4. The futility of the endeavor to obtain a conventional line being recognized, Venezuela for a quarter of a century has asked and striven for arbitration.

5. Great Britain, however, has always and continuously refused to arbitrate, except upon the condition of a renunciation of a large part of the Venezuelan claim and of a concession to herself of a large share of the territory in controversy.

6. By the frequent interposition of its good offices at the instance of Venezuela, by constantly urging and promoting the restoration of diplomatic relations between the two countries, by pressing for arbitration of the disputed boundary, by offering to act as arbitrator, by expressing its grave concern whenever new alleged instances of British aggression upon Venezuelan territory have been brought to its notice, the government of the United States has made it clear to Great Britain and to the world that the controversy is one in which both its honor and its interests are involved and the continuance of which it cannot regard with indifference.

The greater part of the dispatch was taken up with a discussion of the bearing of the Monroe Doctrine upon the case and the most striking feature of it was that the Monroe Doctrine was appealed to by name. Mr. Olney's statement of the Monroe Doctrine is worthy of the most careful consideration as it was the fullest and most definite official construction of its meaning and scope that had been given to the world. He said:
