This is a very good knot used by most of the Miramichi's anglers. I call it the Miramichi knot and it is similar to the Turle Knot but a lot stronger. It is designed to create a straight pull on any salmon up eyed hook but can be used on down eyed hooks too. You may find it harder to tie than the Turle Knot. Personnaly, I've found that the Miramichi knot gives a straight hitch to the fly making it easier to hook a salmon.

To tie the Miramichi Knot, pass the leader through the eye of the hook ( up on up eyed hooks) and allow the fly to slide out of the way. Hold the leader with both hands ( left on the fly side) and make a big loop to the left.
Next step is to make three smaller loops to the left behind the big loop and hold all four loops together between your left thumb and forefinger.

Pass the loose end of the leader through the four loops by the front.
Hold both ends of the leader with your left hand and pull the big loop with your right hand until the knot is tight.

Now bring the fly in the loop, drawing the knot snug on the upper side of the hook. Be careful to avoid catching the hackles of the fly. Pull the fly tightly into position between the fly head and hook eye. Trim the end of the leader.
