How to set the partes of Maister Hoodes staffe together to serue such Astronomicall vses as doe chiefely belong to the Mariner. Chap. 14.

FIrst put the neather ende of the Transame mar∣ked with the 45. degrée into the double socket, so as the Transame may stand right vppe, and that the notch of the socket may méete euen with the sayde 45. degrée, and turne the skrewe that the socket may stand fast at that degrée, that done put the yarde into the crosse socket, so as the notch of the sayd crosse socket may lie iust vppon the 45. degrée of the yarde, and there

make it fast by turning the skrewe: then put on the vane, which to serue Astronomicall vses must be set at the highest ende of the Transame, in such sort as the vpper edge of the vane pearced with the hole may stande eauen with the first point or stréeke of the saide Transame, and when the Transame standeth on the left hande of the yarde, then the vane must be placed on the right side of the Transame: But if the Transame doe stande on the right hande of the yard, then the vane must be placed vpon the left side of the Transame: And the yard and Transame would be so set together as the degrées of the Transame procéeding downeward from one to 45. may looke towards you, that is to say, may stand right before your face: And the degrées of the yarde procéeding from 45. to 90. would lie vpwarde, so as the ende of the yarde marked with 90. may point to your breast or be set to your eye as occasion shall require, for such Astronomicall vses as heere doe followe.
