“…62 'The winds, to which the name of monsoon was originally applied, extend from the Equator to the Tropic of Cancer, embracing all the northern part of the Indian Ocean.' 63 Some geographers mark the beginning of each season when the sun crosses the Equator, so for them the southwest monsoon begins in March or, more generally, April. However, early in the nineteenth century it was 'found that the monsoons followed in the wake of the sun's movements north and south so that they usually set in about May and November, instead of the equinoctial months'.…”

Much is made by some about the supposed superiority of the navigation of one country over another, but the skills of those early mariners, of both the East and the West, were remarkably similar. In the early fifteenth century Arab, Chinese and European methods were fairly basic, with only a primitive compass for directional orientation and other instrumental aids to navigation all in their infancy. Indeed, the age-old 4-Ls of seamanship-lookout, lead, 1 log, 2 and latitude-had not all yet evolved. Many arguments are based on faulty assumptions because of misunderstanding nautical usages and applying modern terms, resulting in an assumption of advanced navigational knowledge in the early fifteenth century.A Chinese sage said words must be used correctly. If not, people will become confused, so take warning about using modern nautical terms for ancient practices. Two of the leading English experts on Eastern navigation, J. V. Mills 3 and G. R. Tibbetts, 4 admit limitations in navigational terminology. It is with the utmost respect that the following suggestions are made.
