Editor's Notes

Hello ,

Hope all is well with you and you are ready for the Wilderness Survivor.

In the last issue of this newsletter I wrote about a very useful piece of outdoor gear, a water filter bottle. But how to make your own water filter? In a wilderness survival situation you maybe not have a water filter bottle.

Enjoy your reading!

Have a safe and fun wilderness trip - Respect and protect the wilderness !

Have you heard about RSS feed?

Then you probably know that for you it could mean Real Simple Subscribing Ė RSS !

RSS is a real simple way for you to subscribe and read the content published at the Wilderness Survival Skills and other of your favorite web sites. "Fast and easy"! No need to click "Get Mail."

It give you as a user total control. Donít want the subscription anymore? You delete it in a second. Total control includes total anonymity, no worries about giving out your e-mail address.

If you have not used RSS yet, you are in for a pleasant surprise...

RSS reader

First you need an RSS reader ! There is two different types of RSS reader. You can use a special software that reads the RSS feeds or a web based RSS reader. There is free version of both alternatives.

Do you want a free RSS reader?

How it works

For each new addition to the web site you receive the updates immediately through your RSS reader. You will see the headline, a short description and a link for you to click, IF you want to read the whole page.

You will see the content without needing to visit the site. That allows you to scan efficiently. Because I guess you will subscribe to more RSS feed then from the web site.

Why do you need an RSS reader? Because each RSS feed is in a non-HTML format called XML. RSS readers can interpret and display that coding, but Web browsers can't. Soon, RSS/XML readers will be part of every browser and e-mail software. But for now, you need a separate reader.

Lets get started!

Visit the Wilderness Survival Skills web site and look for the little orange XML/RSS button!

How to make your own water filter
in a wilderness survival situation.

Always look for clean water. But in a wilderness emergency situation you may face the fact that the only water available is dirty muddy water. To get safe water to drink you need to purify it. But before you can purify it, you've to remove all "visual" particles from the water - you've to filter it.

There are a number of different ways to filter dirty water. One simple way is to make your own sand and gravel filter.

1. To start with, you need a container.

Use whatís available.

If you can find a large, empty can, use it. Punch 5-10 holes around the bottom of the can. A large plastic bottle is also fine. Cut the end of the bottle off evenly.

If there is no container available you have to use what material the nature can provide.

Can you find birch bark? If so make a cone of birch bark. The cone will need to have a fairly small hole in the bottom. Tie the cone with cordage to keep it from opening up. Put a few stones in the very bottom, to help hold your filtering materials in place.

2. Then fill your container with layers of sand and gravel from the bottom to the top.

For sand and gravel use both fine and coarse layers. The bigger the filter, and the more layers you have in it, the better.

If you use a bottle or cone you need to stop the sand to get out of the container. Find some filter material you can place at the bottom. For instance:

- a couple of centimeter (inches) of pebbles,
- a grass mesh, make sure itís nonpoisonous grass, or
- cotton material

If you are lucky and have activated charcoal, make a layer between the sand and the gravel layers. Charcoal helps to remove bacteria and such. Whatís activated charcoal? Read more!

3. Collect some water.

Pour your collected water through the filter. Catch it in another container at the bottom. Look at the water that comes out of the filter. It should be clear! If not you may have to pass the water through the filter more than once.

4. As the last step, you have to purify your water. The water may still contain harmful bacteria that your filter did not remove.

Boil your water or use water purification tablets. Boiling is the most certain way of killing all microorganisms.
