 During the voyage, Hues made astronomical observations of the Southern Cross and other stars of the Southern Hemisphere while in the South Atlantic, and also observed the variation of the compass there and at the Equator. He returned to England with Davis in 1593, and published his discoveries in the work Tractatus de globis et eorum usu (Treatise on Globes and Their Use, 1594), which he dedicated to Raleigh. The book was written to explain the use of the terrestrial and celestial globes that had been made and published by Emery Molyneux in late 1592 or early 1593. Apparently, the book was also intended to encourage English sailors to use practical astronomical navigation, although Lesley Cormack has observed that the fact it was written in Latin suggests that it was aimed at scholarly readers on the Continent. In 1595, William Sanderson, a London merchant who had largely financed the globes'construction, presented a small globe together with Hues' "Latin booke that teacheth the use of my great globes" to Robert Cecil, a statesman who was spymaster and minister to Elizabeth I and James I. Hues'work subsequently went into at least 12 other printings in Dutch (1597, 1613 and 1622), English (1638 and 1659), French (1618) and Latin (1611, 1613, 1617, 1627, 1659 and 1663). In his book An Accidence or The Path-way to Experience: Necessary for all Young Sea-men (1626), John Smith, who founded the first permanent English settlement in North America at Jamestown, Virginia, listed Hues' book among the works that a young seaman should study.
