that a grievance to be redressed is what the words " the dissatisfied
party" contemplate. The clause does not, I think, mean that
whenever there is a difference there must be an arbitration. One
alternative is expressed, viz., settlement by agreement. The clause
supposes that something is done which will stand or prevail unless
steps are taken by the party who objects. That dissatisfied party
is required to arbitrate and not to litigate. But I think he need
do neither and, in that event, he obtains no relief. The thing which
stands may be a progress or other certificate of the architect and
under the express provisions of the contract that carries with it a
liability to pay. If the party dissatisfied with the source of that
liability, viz., the certificate, does give notice, then "unless the
matters in dispute have been otherwise settled, such matters shall
be submitted to arbitration in the following manner." The clause
proceeds to prescribe the manner. After doing so, it provides
(a) that the award shall be "final and binding," and (b) that
"neither party shall be entitled to commence or maintain any action
upon any such breach or dispute until such matter shall have been
referred or determined as hereinbefore provided." The last expres-
sion appears to me to refer to the words "' submitted to arbitration
in the following manner." The sequence in which the successive
directions and restrictions contained in the clause are set out
produces upon a reader the impression that, first, the party dissatis-
fied must give notice, then, unless there be agreement in the mean-
time, there shall be a submission, and the result is to be a binding
award and the exclusion of the alternative, namely, litigation. The
natural way of understanding these successive statements is that
they ensue from and are contingent upon the action of the dissatisfied
party. He has his course pointed out to him and, if he takes it,
he can relieve himself of any liability otherwise flowing from an
