Abstract
More than 25 years ago John Leech [2] published the following beautiful problem: find, whenever possible, trees on n vertices with positive weights on the edges, such that the (n/2) weighted distances among the n vertices are exactly the numbers 1, 2, 3, ..., (n/2). This paper makes a modest progress on this problem.
