Put whole wheat flour into a bowl, and make a well in the middle.
Dissolve yeast and malt syrup in tepid water, pour this into the well, mix in about a third of the meal, cover the bowl with a cloth, and leave in a warm place for two hours.
Add the salt and mix in the remaining flour from the sides of the bowl.
Put mixture into a greased tin and proof, covered, for an hour; bake at 350 degrees F for 45 to 60 minutes.
