To the uninformed public-at-large, there are basically 4 kinds of snakes, all potentially deadly. There are the snakes which are found in or around water, all of which are referred to as Water Moccasins There are those which are found in your yard and are over 2 feet long, all of which are referred to as "Chicken Snakes". There are those which are under 3 feet long and found in your yard and are all referred to as "Gardener Snakes" or Garden Snakes". And finally, there are those that rattle their tails and are referred to as "Rattlers". The presence of actual rattles on the tail is not a requisite feature. Everyone knows that the "Rattlers" that have rattles frequently interbreed with the ones that don't, so some don't have rattles but are equally deadly.
The first and last groups, the "moccasins" and "rattlers" are the most deadly. The proper protocal for dealing with these depends entirely on where you find it. If it's in your yard, you first must emit a blood-curdling scream (so as to warn anyone else within earshot), run and grab a hoe and return to chop it into at least 12 pieces, wait for sundown, then dispose of the pieces in the woods. If it is seen on the road, yell "SNAKE!". Then every effort must be made to run over it at least once. Make sure that you warn the people at the tire store next time you are having a used tire mounted because the snake may have left one of it's fangs in the tire, which will remain deadly to the touch for at least 5 years.
The other two groups, the "gardeners" or Garden Snakes" and the "chicken snakes" don't necessarily have to be killed, but the warning scream is still to be issued. If it is in very close proximity to your home, it is best to go ahead and kill it. A hoe works fine on these too, but you can use a big stick if you want to. It's good to have a few of these snakes around. Nobody really knows why for sure, but some Biologist guy told Delbert down at the filling station that a few years ago, so it must be right. Delbert is usually right about most things.
Make sure to take the pieces as far away from your house as you can right after sundown. If you don't the snake's mate will come looking for it and when it finds the pieces it will set out to bite anyone around. If you get bitten by any of them, as long as you pack some chewing tobacco on the bite right away, you probably won't die.
