The second single change in every Peal must be made between those two bells, and in the same place where the first single change was made; and the whole Hunt, half Hunt, and quarter Hunt, will in course lie in the same places at the second single change, where they lay at the first: either the half Hunt, or quarter Hunt, are alwayes one of the two bells which makes every single change. But there are many other wayes to make the single changes, viz. to make them between the half Hunt, and quarter Hunt, at any dodge, where those two bells do dodge together next before a bob, &c. of which I need not say any thing more in this place, having already set down all those wayes which are most easie and convenient to be practised.
In Ringing this Peal of Grandsire bob, (with any whole Hunt, half Hunt, and quarter Hunt) if there's no single change made within Eighteen-score changes from the beginning of the Peal, the bells will in course come round in their right places, just at the end of Eighteen-score changes.
In any Peal of Grandsire bob, where the first is a double change, and made at the back-stroke, the last change of the Peal (which brings the bells round in their right places) is a treble change, and made at the fore-stroke.
The Seven-hundred and twenty changes of Grandsire Bob may be Rang without making any single change therein, which way of Ringing it, is call'd Grandsire Bob True: that is, the changes are all true trebles and doubles without any single change therein. There are made two double changes (contrary to the course of all the double changes in the Peal) to supply the place of the two single changes, which two are called True changes; and to be made divers wayes, and at several places. The first true change in any Peal may be made at the first, second, or third double bobs either at the first or second bob-change of each. At the first bob-change of any double bob it may be made, by moving the Bell in fourths place down under two Bells at once into the seconds place, and the two hindmost Bells must make a change at the same time: for Example, in the Eighteen-score of treble, second and fourth before set down, at the first bob-change of the first double Bob, the Bells stand thus, 143526. Now the true change is made, by moving the Bell which lies in fourths place down under two Bells at once into seconds place, and the two hindmost Bells are at the same time to make a change thus, 154362. At this place it may be made another way, by moving the hindmost Bell down under two Bells at once into the fourths place, and the two Bells in second and thirds places are at the same time to make a change thus, 134652. At the last Bob-change of each double Bob, it may also be made two wayes; one of which, is to move the Bell in fourths down into the seconds place, and the two hindmost Bells at the same time to make a change, as I shewed you before: But the best and easiest way is to move the bell which lies in fourths place up over two bells at once into the tenors place, and the two bells in second and thirds places to make a change as at a bob: for instance, at the last bob-change of the first double bob in the Eighteen-score before set down, the figures stand thus, 143652. Now the bell in fourths place must be moved up behind, and the two bells in second and thirds places are to make a change, 134526. The second True change in every Peal must be made just Eighteen-score changes from the first, in making of which, these Rules are to be observed. If the first true change in any Peal is made at the first bob-change of a double bob, then the second true change must be made at the first bob-change of the third double bob, accounting from the place where the first true change is made, but not reckoning that for one of the three: or if the first true change is made at the last bob-change of a double bob, then the second true change must be made at the last bob-change of the third double bob, accounting from the place where the first true change was made, but not reckoning that for one of the three. And the second true change in every Peal must be made in the same manner and place as the first, the true and single changes in Grandsire bob, are both to one and the same effect (i.e.) to alter the course of the extream bells; for in making these changes, the whole hunt, half hunt, and quarter hunt are to continue their constant course without variation, neither of those 3 bells being any otherwise concerned therein, than at the change which should have been made, if the single or true change had been forborn.
There is another way to Ring this Peal of Grandsire Bob, by a course differing from the former. When the whole Hunt leads, the half Hunt lies in fifths place, and the quarter Hunt in fourths place, then the next change is a single bob; and when the whole Hunt leads, and the half Hunt lies in fifths place, and the quarter Hunt in thirds place, then the next change is the first bob-change of a double bob; the bobs and dodge-changes herein are made in the same manner, as those in the former way: But the bobs herein are called by a Rule differing from the former, viz. when the whole Hunt and half Hunt do lie together before the bells, and the quarter Hunt (lying in fourths place) dodges with the bell in thirds place, then the second time the whole Hunt comes before the bells (from that place) there is made the first bob-change of a double bob, the second bob-change being made the next time the whole Hunt leads after. When the whole Hunt and half Hunt, do lie together before the bells, and the quarter Hunt (lying in fifths place) dodges with the bell in tenors place, then the second time the whole Hunt leads (from that place) is made a single bob.
There are two single changes in the Seven-hundred and twenty, the first single change in any Peal may be made at the first, second, or third single bobs, at which places it must be made between the 2 hindmost bells; or the first single change may be made the next time the whole Hunt leads after the first, second, or third single bobs, at which places 'tis alwayes made between the two hindmost bells. The first single change may also be made the next time the whole Hunt leads after the last bob-change of the first, second, or third double bobs, where it must alwayes be made in third and fourths places. But in some few Peals it happens, that the bells will come round at the fore-stroke the next time the whole Hunt leads after the third single bob, and also after the last bob-change of the third double bob, which falls out according as the first bob-change in each Peal is made, either nearer the beginning, or farther off.
The second single change (in every Peal) must be made Eighteen-score changes from the first, in making of which, these Rules must be observed.
If the first single change is made at a single bob, then the second single change must be made at the third single bob from the place where the first was made. Or if the first single change is made the next time the whole Hunt leads after a single bob, then the second single change must be made the next time the whole Hunt leads after the third single bob, accounting from the place where the first single change was made. And the same Rule is observed in making it after a double bob.
The second single change in every Peal must be made in the same place, and between those two bells which made the first single change: But (in Ringing this Peal) if you make no single change, the bells will in course come round at the end of Eighteen-score changes.
The way to begin several of these Peals, is as follows.
