My Method of Execution.
CALCULATIONS AND APPARATUS.
My method of execution is the outcome of the experience of my
predecessors and myself, aided by suggestions from the doctors, and is
rather the result of gradual growth than the invention of any one man.
The Drop.
The matter which requires the greatest attention in connection with an
execution is the allowance of a suitable drop for each person executed,
and the adjustment of this matter is not nearly so simple as an
outsider would imagine.
It is, of course, necessary that the drop should be of sufficient
length to cause instantaneous death, that is to say, to cause death by
dislocation rather than by strangulation; and on the other hand, the
drop must not be so great as to outwardly mutilate the victim. If all
murderers who have to be hanged were of precisely the same weight and
build it would be very easy to find out the most suitable length of
drop, and always to give the same, but as a matter of fact they vary
enormously.
In the earliest days of hanging it was the practice for the executioner
to place his noose round the victim's neck, and then to haul upon the
other end of the rope, which was passed through a ring on the scaffold
pole until the culprit was strangled, without any drop at all. After a
while the drop system was introduced, but the length of drop given was
never more than three feet, so that death was still generally caused
by strangulation, and not by dislocation, as it is at present. One
after another, all our English executioners followed the same plan
without thought of change or improvement, until Mr. Marwood took the
appointment. He, as a humane man, carefully considered the subject, and
came to the conclusion that the then existing method, though certain,
was not so rapid or painless as it ought to be. In consequence he
introduced his long-drop system with a fall of from seven to ten feet,
which caused instantaneous death by severance of the spinal cord. I
was slightly acquainted with Mr. Marwood before his death, and I had
gained some particulars of his method from conversation with him; so
that when I undertook my first execution, at Edinburgh, I naturally
worked upon his lines. This first commission was to execute Robert
Vickers and William Innes, two miners who were condemned to death for
the murder of two game-keepers. The respective weights were 10 stone 4
lbs. and 9 stone 6 lbs., and I gave them drops of 8 ft. 6 in. and 10
ft. respectively. In both cases death was instantaneous, and the prison
surgeon gave me a testimonial to the effect that the execution was
satisfactory in every respect. Upon this experience I based a table of
weights and drops. Taking a man of 14 stones as a basis, and giving him
a drop of 8 ft., which is what I thought necessary, I calculated that
every half-stone lighter weight would require a two inches longer drop,
and the full table, as I entered it in my books at the time, stood as
follows:--
14 stones 8 ft. 0 in.
13½ " 8 " 2 "
13 " 8 " 4 "
12½ " 8 " 6 "
12 " 8 " 8 "
11½ " 8 " 10 "
11 " 9 " 0 "
10½ " 9 " 2 "
10 " 9 " 4 "
9½ " 9 " 6 "
9 " 9 " 8 "
8½ " 9 " 10 "
8 " 10 " 0 "
This table I calculated for persons of what I might call "average"
build, but it could not by any means be rigidly adhered to with safety.
For instance, I have more than once had to execute persons who had
attempted suicide by cutting their throats, or who had been otherwise
wounded about the neck, and to prevent re-opening the wounds I have
reduced the drop by nearly half. Again, in the case of persons of very
fleshy build, who often have weak bones and muscles about the neck, I
have reduced the drop by a quarter or half of the distance indicated by
the table. If I had not done so, no doubt two or three of those whom I
have executed would have had their heads entirely jerked off,--which
did occur in one case to which I shall again refer. In the case of
persons with scrofulous tendencies it is especially necessary that the
fall should be unusually short, and in these cases I have at times
received useful hints from the gaol doctors.
Until November 30th, 1885, I worked to the scale already given, but on
that date I had the awful experience above referred to, which caused
me to reconsider the whole subject and to construct a general table on
what I believe to be a truly scientific basis. The experience referred
to is dealt with in another chapter. The man with whom it occurred
was Robert Goodale, whom I executed at Norwich Castle. He weighed 15
stones, and the drop indicated by the first table would therefore be 7
ft. 8 in., but in consequence of his appearance I reduced it to 5 ft.
9 in., because the muscles of his neck did not appear well developed
and strong. But even this, as it turned out, was not short enough, and
the result was one of the most horrible mishaps that I have ever had.
As will be seen from the full report of this case, in another chapter,
the coroner exonerated me from all blame and testified to the careful
way in which I had done my work; but I felt that it was most necessary
to take every possible precaution against the recurrence of such an
affair. I, therefore, worked out a table of the striking force of
falling bodies of various weights falling through different distances;
which table I give on page 34. Working with this, I calculate that an
"average" man, of any weight, requires a fall that will finish with a
striking force of 24 cwt., and if the convict seems to require less,
I mentally estimate the striking force that is necessary, and then
by referring to the table I can instantly find the length of drop
required. To see how this new table works out we may take the case of
Robert Goodale again. As he weighed 15 stones his striking force with
a drop of 2 feet would be 21 cwt. 21 lbs., or with a drop of 3 feet
26 cwt. 7 lbs., so that if he were a man of ordinary build the drop
necessary would be 2 ft. 6 in. As I estimated from his appearance that
his drop ought to have been about one-sixth less than the standard, I
should have given him, working on this new table, about 2 ft. 1 in.
instead of the 5 ft. 9 in. which was actually given. This is an extreme
case, with a very heavy man, but all through the table it will be found
that the drop works out shorter than in the first table. For instance,
Vickers and Innes, the two Edinburgh murderers previously referred to
would have had their drops reduced from 8 ft. 6 in. and 10 ft. to 5 ft.
6 in. and 7 ft. respectively if they had been treated according to the
present revised table.
On August 20th, 1891, at Kirkdale Gaol, Liverpool, at the execution of
John Conway, an attempt was made to dictate to me the length of drop,
and a most unfortunate scene ensued. From seeing the convict, Conway, I
had decided that the drop ought to be 4 ft. 6 in., a little under the
scale rate; and I was surprised and annoyed at being told by Dr. Barr,
acting, I believe, under authority, that I was to give a drop of 6 ft.
9 in. I said that it would pull the man's head off altogether, and
finally refused to go on with the execution if such a long drop were
given. Dr. Barr then measured off a shorter drop, some ten or twelve
inches shorter, but still much longer than I thought necessary, and
I reluctantly agreed to go on. The result, everyone knows. The drop
was not so long as to absolutely pull off the victim's head, but it
ruptured the principal blood-vessels of the neck.

I do not know who was really responsible for the interference with my
calculation, but do not think that the long drop was Dr. Barr's own
idea, as the drop which I suggested was on the same system as he had
previously commended, and was almost identical with the drop that would
have worked out on the basis of his own recommendation in a letter to
the _Times_ some years ago. Dr. Barr's letter to me, written in 1884,
was as follows:--
1, St. Domingo Grove,
Everton,
Liverpool, _Sept. 2nd, 1884_.
Sir,
In compliance with your request I have pleasure in giving you a
certificate as to the manner in which you conducted the execution
of Peter Cassidy in H.M. Prison, Kirkdale. I may now report the
statement which I gave in evidence at the Inquest, "that I had
never seen an execution more satisfactorily performed." This was
very gratifying to me.
Your rope was of excellent quality; fine, soft, pliable, and
strong. You adjusted the ring, directed forwards in the manner in
which I have recommended in my pamphlet, "Judicial Hanging." You
gave a sufficient length of drop, considering the weight of the
culprit, and completely dislocated the cervical vertebræ between
the atlas and axis (first and second vertebræ). I have reckoned
that the weight of the criminal, multiplied by the length of
the drop, might range from 1120 to 1260 foot pounds, and I have
calculated that this _vis viva_ in the case of Cassidy amounted to
1140 foot pounds.
The pinioning and other details were carried out with due decorum,
I hope, whoever be appointed to the post of public Executioner,
may be prohibited from also performing the part of a "showman" to
gratify a depraved and morbid public curiosity.
JAMES BARR, M.D.,
Medical Officer, H.M. Prison, Kirkdale.
To Mr. James Berry.
A few days after Conway's execution I received a letter from a
gentleman in the South of London, shortly followed by a second letter,
and as they throw some useful light upon the subject I give them
in full--omitting the writer's name, as he does not wish it to be
published.
_August 22nd, 1891._
_Re_ the Execution at Kirkdale.
Sir,
As the accident attending the execution on the 20th inst. at
Kirkdale may be falsely, and very unjustly, charged to your
account, and at the same time be brought forward by a mass of
misguided people as a reason for the total abolition of capital
punishment, I think the following remarks on the subject of hanging
may not be out of place.
Some years ago, Dr. James Barr, medical officer at Kirkdale Gaol,
published a letter in the _Times_ regarding what he considered the
proper length of drop. He said that the length of drop ought to be
such as to produce a momentum of 2600 lbs., meaning by "momentum,"
the convict's weight multiplied by the velocity of his descent at
the end of the fall. Now, in estimating the convict's weight, I
conceive that you ought to leave out the weight (as far as you can
guess it) of his head, because the weight of his head is supported
by the noose when the jerk takes place, and, therefore, cannot
affect the amount of pull, or strain, on the neck. From what Dr.
Barr says regarding the 2600 lbs. momentum, it is easy, by a little
mathematics, to deduce the following rule.
To find length of drop in feet, divide the number 412 by the square
of the convict's weight of body in stones.
By the above rule I constructed the following table:--
Weight of body without head. Length of drop.
15 stones 1 ft. 10 in.
14 " 2 " 2 "
13 " 2 " 6 "
12 " 2 " 11 "
11 " 3 " 5 "
10 " 4 " 2 "
9 " 5 " 1 "
8 " 6 " 6 "
7 " 8 " 5 "
Convict Conway's weight, you are reported to have said, was 11
stones 2 lbs. Leaving 1 stone for the weight of his head, which
is perhaps more than sufficient, his hanging weight would be 10
stones 2 lbs, so that a drop of 4 feet and a few inches[B] would
have been, according to the doctor's rule, quite enough for him.
Regarding the value of the rule, I am, of course, unable to speak;
nor do I know, from what I remember of the doctor's letter, that he
meant the 2600 lbs. momentum to apply in all cases. Much depends on
the convict's build, strength of neck, etc.
Yours truly,
X. Y.
(Second letter.)
_August 25th, 1891._
_Re_ the Execution at Kirkdale.
Sir,
In constructing the table I sent you two days ago, I find that I
have made an absurd mistake. It arose from my carelessly taking a
stone weight as 16 lbs., instead of 14 lbs., which I beg you to
allow me correct. Instead of the number 412, I ought to have given
the number 539. The corrected rule based on Dr. Barr's momentum of
2600 lbs. is, therefore, as follows:--Length of drop, in feet, is
found by dividing the number 539 by the square of the number of
stones in weight of convict's body, exclusive of the weight of his
head. Thus, if a convict weighs 11 stones altogether, and we take
his head as 1 stone, we have length of drop = 539/100 = 5·39 feet
(5 ft. 5 in. nearly).
The table, corrected, stands thus:--
Weight of body without head. Length of drop.
15 stones 2 ft. 5 in.
14 " 2 " 9 "
13 " 3 " 2 "
12 " 3 " 9 "
11 " 4 " 6 "
10 " 5 " 5 "
9 " 6 " 8 "
8 " 8 " 3 "
7 " 11 " 0 "
In allowing, in the case of convict Conway, who weighed 11 stones
2 lbs., 1 stone for the head, I may be allowing too much; it is a
mere guess. If his head weighed 9 lbs., the drop ought to have been
4 ft. 10 in.
Yours truly,
X. Y.
P.S.--A mistake of 3 or 4 lbs. in estimating weight of head makes,
you will see, a considerable error in calculating the drop.
It will be seen that this calculation, which does not include the
weight of the head in a man's hanging weight, works out the drop to a
rather greater length than my own table, but the difference is only
small, and I have always found my own table give quite sufficient drop.
The Rope.
The apparatus for carrying out the extreme penalty of the law is very
simple. The most important item is the rope, which must necessarily
possess certain properties if the death of the condemned person is to
be instantaneous and painless.
For successful working the rope must, of course, be strong, and it
must also be pliable in order to tighten freely. It should be as thin
as possible, consistent with strength, in order that the noose may be
free running, but of course, it must not be so thin as to be liable to
outwardly rupture the blood vessels of the neck.
Before undertaking my first execution I gave careful consideration to
the question of the most suitable class of rope, and after trying and
examining many varieties, I decided upon one which I still use. It is
made of the finest Italian hemp, ¾ of an inch in thickness. Before
using a rope for an execution, I thoroughly test it with bags of cement
of about the weight of the condemned person, and this preliminary
testing stretches the cord and at the same time reduces its diameter
to 5/8 of an inch. The rope consists of 5 strands, each of which
has a breaking strain of one ton dead weight, so that it would seem
unnecessary to test it from any fear of its proving too weak, but the
stretching and hardening which it undergoes in the testing makes it
far more "fit" and satisfactory for its work than a new, unused rope
would be.
It has been said that I use a rope with a wire strand down the centre,
but the notion is so ridiculous that I should not refer to it if it
were not that many people seem to believe it, and that more than once
it has been stated in the newspapers. A rope with a wire strand would
possess no possible advantage that I can see, and it would have so many
practical disadvantages that I do not think anyone who had studied the
matter would dream of using such a thing. At any rate I have not done
so, and I know that neither Mr. Binns nor Mr. Marwood ever did. Mr.
Marwood used ropes of about the same quality and thickness as my own,
while Mr. Binns used a much thicker rope (about 1¼ inch diameter after
use), of a rougher and less pliable class of hemp.
Until the commencement of 1890 I supplied my own ropes, some of which,
however, were made to order of the Government, and I was able to use
the same rope again and again. One I used for no less than sixteen
executions, and five others I have used for twelve executions each.
These are now in the possession of Madame Tussaud. At the beginning
of 1890 a new rule was made under which a new rope is ordered to be
supplied and used for most of the executions in England, and to be
burned, together with the clothes of the person executed (which were
formerly a perquisite of the executioner) by the prison officials
immediately after the execution. In Scotland and Ireland I still
provide my own ropes.
The rope I use is thirteen feet long and has a one-inch brass ring
worked into one end, through which the other end of the rope is passed
to form the noose. A leather washer which fits the rope pretty tightly,
is used to slip up behind the brass ring, in order to prevent the noose
slipping or slackening after it has been adjusted.
In using the rope I always adjust it with the ring just behind the
left ear. This position I never alter, though of course, if there were
any special reason for doing so, for instance, if the convict had
attempted suicide and were wounded on the side of the throat, death
could be caused by placing the ring under the chin or even behind the
head. The position behind the ear, however, has distinct advantages
and is the best calculated to cause instantaneous and painless death,
because it acts in three different ways towards the same end. In the
first place, it will cause death by strangulation, which was really the
only cause of death in the old method of hanging, before the long drop
was introduced. Secondly, it dislocates the vertebra, which is now the
actual cause of death. And thirdly, if a third factor were necessary,
it has a tendency to internally rupture the jugular vein, which in
itself is sufficient to cause practically instantaneous death.
Pinioning Straps, Etc.
The pinioning arrangement, like the rest of the arrangements for an
execution, are very simple. A broad leathern body-belt is clasped
round the convict's waist, and to this the arm-straps are fastened.
Two straps, an inch and a half wide, with strong steel buckles, clasp
the elbows and fasten them to the body-belt, while another strap of
the same strength goes round the wrists, and is fastened into the
body-belt in front. The legs are pinioned by means of a single two-inch
strap below the knees. The rest of the apparatus consists of a white
cap, shaped somewhat like a bag, which pulls down over the eyes of the
criminal to prevent his seeing the final preparations.
[Illustration: Plan and elevation of the Drop.]
The Scaffold.
Until recently, the scaffolds in use in the various gaols differed very
much in the details of their construction, as there was no official
model, but in each case the local authorities followed their own idea.
In 1885, however, a design was drawn, in the Surveyors' Department
of the Home Office, by Lieut.-Col. Alten Beamish, R.E. Before being
finally adopted, the design was submitted to me; and it seemed a
thoroughly good one, as, indeed, it has since proved to be, in actual
practice. The design is supplied to the authorities of any gaol where a
scaffold is to be erected, from the Engineers' Department at the Home
Office; and, with a slight alteration, has been the pattern in general
use to the present day. The alteration of which I speak, is a little
one suggested by myself, and consists of the substitution of a slope,
or a level gangway, in place of the steps. I had found in some cases,
when the criminals were nervous or prostrated, that the steps formed a
practical difficulty. The slope, or gangway, was approved by the Home
Office, and was first used on April 15th, 1890, at Kirkdale Gaol, for
the execution of Wm. Chadwick. It was a simple improvement, but it has
turned out to be a very useful one.
At most of the gaols in the country the scaffold is taken to pieces and
laid away immediately after use, but in Newgate, Wandsworth, Liverpool,
and Strangeways (Manchester), it is kept standing permanently.
The essential parts of the scaffold are few. There is a heavy
cross-beam, into which bolts terminating in hooks are usually fastened.
In some cases this cross-beam stands on two upright posts, but usually
its ends are let into the walls of the scaffold house. Of course, the
hooks fastened to it are intended to hold the rope.
The scaffold proper, or trap, or drop, as it is variously called, is
the portion of the structure to which most importance is attached,
and of which the Government furnishes a plan. It consists of two
massive oaken doors, fixed in an oak frame-work on a level with the
floor, and over a deep bricked pit. The plan and section will explain
the arrangement. The two doors are marked A A and B B on the plan.
The door A A is hung on three strong hinges, marked C C C, which are
continued under the door B B. When the trap is set the ends of these
long hinges rest on a draw-bar E E, as shown in the plan. The draw-bar
is of iron, 1¼ in. square, sliding in strong iron staples, F F F, which
fit it exactly. When the lever D is pulled over in the direction of
the little arrow, it moves the draw-bar in the opposite direction,
so that the ends of the long hinges drop through the openings H H H,
and the two doors fall. To set the trap the door B B has to be raised
into a perpendicular position, until the other door is raised and its
hinges placed on the draw-bar. The arrangement is a very good one; as
both doors must necessarily fall at exactly the same moment. Their
great weight--for they are of three inch oak--causes them to drop very
suddenly, even without the weight of the criminal, and they are caught
by spring catches to prevent any possibility of rebound.
