The search for the El Dorado came afterwards, and is still urging men north to the Yukon, south to the Cape, and in a south-easterly direction to "Westralia." Besides the general treatment in the text and the special details in the Appendix, I have also attempted to tell the story once more in a series of maps showing the gradual increase of men's knowledge of the globe.

It would have been impossible to have included all these in a book of this size and price but for the complaisance of several publishing firms, who have given permission for the reproduction on a reduced scale of maps that have already been prepared for special purposes.

I have specially to thank Messrs.
Macmillan for the two dealing with the Portuguese discoveries, and derived from Mr.Payne's excellent little work on European Colonies; Messrs.

Houghton, Mifflin, & Co., of Boston, for several illustrating the discovery of America, from Mr.J.Fiske's "School History of the United States;" and Messrs.

Phillips for the arms of Del Cano, so clearly displaying the "spicy" motive of the first circumnavigation of the globe.
I have besides to thank the officials of the Royal Geographical Society, especially Mr.Scott Keltie and Dr.H.R.Mill, for the readiness with which they have placed the magnificent resources of the library and map-room of that national institution at my disposal, and the kindness with which they have answered my queries and indicated new sources of information.
