To anyone who has made a careful study of aeronautics and its possibilities in the commercial world it is evident that South America offers unusual opportunities for development by aircraft, and of all South American countries Peru, on account of its climate, its rich natural resources, its geographical position and its peculiar topographical configairation, is almost ideal. To fully appreciate the significance of this remark it is necessary to have a very clear conception of all those factors which go to make aerial transport a commercial possibility.

The question of whether it is possible to construct very large aeroplanes equal or superior in efficiency to the smaller aeroplanes already in existence is a subject that must be occupying the minds of people connected with aeronautics.

The subject has been considered by various aeronautical engineers and scientists in the pages of the ROYAL AËRONAUTICAL JOURNAL and elsewhere.

A few of the statements of conclusions arrived at are quoted from the AËRONAUTICAL JOURNAL of 1917 in an appendix.

In England there is no doubt that the late Colonel Cody was the pioneer of the large aeroplane, as although his plane would be considered to be of moderate dimensions to-day, yet it was large in relation to its contemporaries.
