<P>PROBLEM TO BE SOLVED: To provide a guidance channel for rescuing small animals and animate beings, inhabiting a village forest and arable land, because they often light on an agricultural irrigation channel or a side ditch channel and fall thereinto, when they migrate from places where they have long lived, for the purpose of feeding and breeding. Ž<P>SOLUTION: The guidance channel is formed by splicing an L-shaped block B so as to form the guidance channel in a side ditch block E forming the channel. Fill on an inclined plane for escape is formed by mixing dry clay with removed soil, collected on a channel construction site, in the guidance channel. Thus, the small animals and animate beings, falling into the agricultural irrigation channel or the side ditch channel, can escape by getting into the guidance channel while being guided by the odor and feeling of soil in the places where they have long lived, because they remember the odor and feeling.
