Wow, this is me, doing a blog like a really modern person!

This posting is mainly for Jared, to show him the canal and the lock system in France. In the old days they used to move lots of cargo around by barges (big flat boats) pulled by horses.  They made canals for the boats to go on, and they built locks to help the boats go up and down the hills. I went for a bike ride along the canal, and took photos of a boat going through a lock, to show you how it works.  Now the canals are used mostly by people on holiday who own or hire boats, and the paths beside the canals are used for walking and cycling. The locks are really cool, and lots of people watch whenever a boat goes through one, and if you’re really lucky the lock-keeper will let you help (especially boys around 8 years old!) I helped the lock-keeper close this one after I took the pictures.

This is a lock-keeper's house.

Sometimes the lock-keeper lives in the house, sometimes they just stay there during the day to let the boats through.

the top of the lock

This is where the boat will enter if it comes from up-hill

This is where the boat will sit when it is going up or down.

The bottom of the lock

This is where the boat will come out if it is going down-hill.

Here comes a boat!
Here comes a boat!

This boat is coming from up-hill, and it needs to get down the hill.

so the lock-keeper starts to open the top gate...
so the lock-keeper starts to open the top gate…
she turns and turns to open the first gate...
she turns and turns to open the first gate…
she gets one gate open...
she gets one gate open…

and then she runs around to the other side to open the other top gate.

The boat drives into the lock...
The boat drives into the lock…
slowly and carefully....
slowly and carefully….
it's a big boat...
it's a big boat…
so it's a tight squeeze!
so it's a tight squeeze!
The lock-keeper closes the top gate again.

The boat owner has to help her because there aren’t any 8 year old boys around.

they turn and turn the levers....
they turn and turn the levers….
and finally get the top gates closed again.
and finally get the top gates closed again.

So the boat is now in the lock, and is at the level of the water up-hill. They need to let it down to the level of the water down-hill!

so she starts to let some water out the bottom of the lock
so she starts to let some water out the bottom of the lock
and as the water comes out the boat sinks down
and as the water comes out the boat sinks down
If you look at the boat and the people's heads
If you look at the boat and the people's heads
you can see the boat dropping down...
you can see the boat dropping down…
and down, until it's at the level of the down-hill water!
and down, until it's at the level of the down-hill water!

So now it’s time to open the bottom gates to let it out.

so again the lock-keeper has to open the gates herself
so again the lock-keeper has to open the first gate
and then the second gate all by herself
and then the second gate all by herself

because there are no eight year olds around to help.

but when it's done the boat can leave the lock
but when it's done the boat can leave the lock
downhill...
and sail off downhill…
happily...
happily…

Hope you get to come to France and help with a lock sometime J
