Bowl Speed and Control
The speed that the bowl travels towards the head is generated by
-          the pendulum arm swing and
-          the forward body movement.

Bowl speed is both a mental process and a physical process.
Concentrate on how far then how fast – focus on the finishing point
Adjust the delivery speed according to the result of the previous bowl
If your bowl is too long slow the delivery process down
If it is too short quicken the delivery process
Speed of the bowl is controlled by arm speed which in turn controls body movement

REFLECTIONS OF A NEW BOWLER
When I contemplated playing bowls, I knew not what to do.
About how to enter a game, I didn't have a clue.
I arrived in time for my first game, I think they called it fours.
Took all the bowls out of my bag, I didn't know the laws,
The other guys explained to me, "You've made a silly blue."
I said, "what's the point of having four if you're only using two." 

My opponent whispered in my ear, "In time you'll work it out,
But here's a thing you'll learn right now, it's up to you to shout."
I rushed into the bar and yelled, "Eight pots of beer, I think,
You'd better make it Tui, is it the stuff they drink?"
I brought the tray back to the green and handed drinks around,
The coin was tossed, the mat went down, my coin was never found.

You only had to buy two drinks you stupid bloody cluck."
"You should have told me sooner pal, I could've saved ten bucks."
We all shook hands, the day was fine, the green was running fast,
"I've never played this game before, do you mind if I go last?"
The skipper looked me up and down, he began to fear the worst,
"If you’re a novice bowler mate, it's best if you go first." 

I took a run up to the mat as nervous as could be,
It hit his foot, ran up his leg, rebounding off his knee.
"You're just a little quick my son", I saw my skipper mime,
"You've got another bowl mate, try underarm this time."
My team mates tried to counsel me, "Calm down, you'll get the ticket."
I've just turned sixty two ," I said, "and just retired from cricket."

If I played a bowl that fell well short the skip went off his rocker.
But when he did a similar thing, he was trying to play a blocker.
If I played a bowl well past the head, he said, "You'll get the knack."
If the skip did the same as me, "It's in case they trail the jack."
"Now listen old son", he said, his face was stern and gritty,
"Your job in this game of bowls is drawing to the kitty". 

I apologised for my mistakes and took in what he said,
"I'm sorry Mr Skipper, sir, I must have lost my head."
My first attempt at playing bowls was really quits a farce,
The skipper kept on telling me, "You've got to take some grass".
I stood and watched the other bloke as he took his turn to bowl,
It was then I learnt that taking grass was not the sort you roll.

Law 28.6         Bowl displacement by a bowl from a neighbouring rink
If a bowl at rest is in danger of being moved by a bowl from the neighbouring rink any player at the head can choose whether to lift the bowl at rest to allow the other bowl to pass and then replace it, as long as this action would not influence the outcome of the head, or stop the bowl from the neighbouring rink. 

NB:  If your team’s bowl is coming through the neighbouring rink, inform them to watch their head. Do not go rushing into their head unless you are invited to assist
