Karim:
        
        
          Mr. Beaver, you said that you construct the
        
        
          dam to build a home. But I cannot see anything that looks
        
        
          like a home. There is only a pile of logs. Where do you
        
        
          build your home?
        
        
          Mr. Beaver:
        
        
          You are right. You cannot see our home
        
        
          from the outside. We build it like this on purpose so that
        
        
          it is a safe haven. While constructing the dam, we also
        
        
          prepare our home on the banks of the pond, close to the
        
        
          shore. Our home looks like a pile of wood from the
        
        
          outside. But this should not fool you; we design the
        
        
          inside carefully. First of all, security is of great importance
        
        
          to us. For that is why the only entrance to our home is
        
        
          underwater. Of course, not everyone can easily enter it.
        
        
          We pass through secret tunnels to go in and out.
        
        
          Karim:
        
        
          This is great. Your house is like a castle
        
        
          surrounded by ditches. It is virtually impossible to enter.
        
        
          Mr. and Mrs. Beaver laugh at Karim’s remark.
