  may impose an easement on the land to continue during the time that the lease
  
  exists or for any shorter period.
  (b) A is tenant for his life of certain land with remainder to B
  
  absolutely. A cannot, unless with B’ consent, impose an easement thereon which
  
  will continue after the determination of his life interest.
  (c) A, B and C are co-owners of certain land. A cannot, without
  
  the consent of B and C, impose an easement on the land or on any part thereof.

  term of five years and B of a field Y for a term of ten years. A's interest

  a right of way terminable with A's lease.
