Ixodes ricinus and Lyme disease


This charming looking insect is Ixodes ricinus or the hard bodied tick. (The penny is 15mm in diameter.)

It preys on mammals by sucking their blood and storing it in its abdomen. It particularly likes rabbits, sheep, deer and sea kayakers. This year seems a bad season for them and it is worth examining yourself after walking through vegetation like bracken. They climb it in wait and anticipation of feasting upon their next victim.


Traditionally people have pulled then out with their nails or tweezers, burned them off with a cigarette or attempted to suffocate or stun them using Vaseline or alcohol. Unfortunately all these methods cause the little creature to dig further in and to puke its stomach contents into the victim's blood stream. This partially digested blood is a heady cocktail that contains another of God's creations, a spirochete bacterium called Borrelia burgdorferi sensu lato. This causes a condition called Lyme disease in humans. Believe me (and I am a doctor), Lyme disease is something you would much prefer not to have.

Public service announcement: if you get a red ring spreading out from a tick bite you should seek medical advice, mention you have been bitten by a tick and you are concerned about Lyme disease.

A much safer way to remove the injurious, illegitimate and far from insignificant insects is to use a little rotating hook such as the O'Tom, available from all good veterinary surgeries. You slide the tapered fork behind its bloated abdomen then slowly twist without pulling. The tick can resist a pull by digging in with its jaws and fore feet but it's helpless against gentle rotation. Some favour anticlockwise and others clockwise rotation. My own experience is that both are equally effective.

Are you curious what to do with the now pitifully struggling insect which you have untimely ripped from its natural element? Well, this might not be good for your Karma, but the following is my humble suggestion. I take some delight in burning the hapless former parasite.

If only it was so easy to get revenge on the Scottish midge.

Ayrshire agate



This banded agate was found on the south Ayrshire coast under the cliffs on which Culzean Castle stands. Agates form as nodules within cooling lava. As the lava weathers the nodules are released and get broken open by wave action. They are also found on Ayrshire's raised beaches which are used to grow Ayrshire potatoes. Hunters of the semi precious stones will often follow the tractors which plough the fields.

Tiderace Seakayaks.



Tiderace Seakayaks is a new name on the UK sea kayaking scene. Aled Williams (formerly of Rockpool kayaks and designer of the delectable Alaw and Alaw Bach) has decided to rename his new company (formerly known as In-Uit Kayaks) in respect of the tradition and culture of the Inuit people who come from the Arctic territories of Alaska, Canada and Greenland. Michael, who has spent a great deal of time with these people, has already drawn attention to the appropriateness of the name. I am sure Aled chose the name out of respect to the Inuit origins of our sport. I am equally sure that Aled has made the correct and sensitive decision to rename the company.

I like the name Tiderace and here is Kenny paddling an Aled designed boat in a tide race: the Cuan Sound.

Crossing to Scarba


Leaving the fertile grassy slopes of the

Garvellachs, we headed south east for Scarba. It is a barren and rocky isle with few places to land. We stopped here for a second luncheon whilst we waited for a favourable tide in the Corryvreckan. In this view the Garvellachs can be seen in the middle distance with Mull beyond.


The GPS track of our route.


From the Garvellachs the horizon to the south east is blocked by Scarba on the left and Jura on the right. From this distance the Gulf of Corryvreckan, which lies between, them looks like a sheltered sea loch.


There is a raised beach on top of a line of cliffs which surround most of Scarba's coast. This means that even if you can find a landing spot, access to the interior is barred by the cliffs. No wonder the 5th century monks chose the Garvellachs!

Eithne's grave.


This simple stone, incised with a Celtic cross, can be found on a peaceful knoll, high above the monastery on Eileach an Naoimh in the Garvellachs.


We have wandered and spent time reflecting here several times before traversing the tides of the Grey Dogs or the Corryvreckan. I have always enjoyed the contrasting emotions experienced on such sea kayaking trips.

The grave is thought to be the last resting place of St Columba's mother, Eithne.
