Colledge Bob the fifth. When the Treble leaves the two hind bells, they dodg until it comes there again. And when it leaves the two first bells they lie still one change, dodg the next, and so by turns until it comes down there again; during which time the bells in the third and fourth places dodg except when the Treble hindereth them.
By these methods each of them will go 120 changes, and by making of bobs they will go 240, 360, or 720. In the first of them the bell in the second place lieth still at the bob-changes, and in the other four the bell in the fourth place always lieth still.
To ring 240. Every time the half-hunt dodgeth behind a bob must then be made, as in these peals here prickt; where, in the first peal the 4 is the half-hunt, and in the other four peals the 2 is the half-hunt.
To ring 360. Every time the half and quarter-hunts dodg together behind, a bob must then be made.
To ring 720. Every time the half-hunt dodgeth behind a bob must then be made, except when the quarter-hunt dodgeth there with it, and then not.
In the 360 or 720 of each peal the 2 may be the half-hunt, and 4 the quarter-hunt or others at pleasure.
The Experiment.
Triples and Doubles. The Treble is the whole-hunt, but never hunteth up farther than the fourth place, for the four first bells go Doubles and Singles; and every time the Treble leads an extream is made in the third and fourth places, according to the common course of doubles and singles upon, four bells; which course of doubles and singles must be continued, the two hind bells in the mean time dodging, until the making of the first Parting change, which will separate the two hind bells; and then the four first bells go the same course of doubles and singles again, the two hind bells dodging as before, until the making of the second Parting change, and so successively. The Parting change is a double change on the four middle bells, and made at the leading of the Treble. The first Parting change may be made either at the first second or third leading of the Treble, observing, that whatsoever bell in the first Parting change moves down to the Treble, when the Treble leads and that bell lieth next it again, the second Parting change must then be made. And whatsoever bell in the second Parting change moves down to the Treble when the Treble leads, and that bell lieth next it again, the third Parting change must then be made, and so successively. There being five Parting changes in the Peal, and as many half-hunts, each of the bells (the Treble excepted) taking that place one after another; and consequently, the five persons that ring them must call the Parting changes one after another as their turn comes, according to the aforesaid rule.
Changes upon Seven Bells.
The methods upon five may be prickt upon seven, observing but the true difference of proportion in the changes; that is, doubles upon five bells must be triples upon seven; doubles and singles upon five must be triples and doubles upon seven, &c.
