    The main purpose of this paper is to resolve an open problem stated by Graham, viz. Knowlton-Graham partitions of order \(m\) do exist for all \(n\) in the range \((\begin{smallmatrix} m+ 1\\ 2\end{smallmatrix})\leq n\leq J(m)\). The proof involves a construction of \(0-1\) matrices having row and column sums without gaps.
