MORNINGTON BRANCH OF THE PORT PHILLIP FARMERS' SOCIETY.
The number of teams and ploughs assembled on the ground amounted to 15; viz., eight horse and seven bullock ploughs, being three in excess of last year ; and it is but justice to state, that in the display on this occasion a very decided improvement was evinced, both as to the quality of the teams and the care and skill of the workmen contesting for the prizes.
On the completion of the work allotted to the various competitors, the Judges, Messrs Dick, Wade and Leckie, proceeded to their inspection, and handed in their awards, as follows :

Most of the leading gentry and agriculturists of the district, together with a sprinkling of the fair sex, visited the field during the progress of the match, and in the evening were hospitably entertained by the worthy proprietor.
The vice chair was occupied by A. Patterson, Esq., to whose exertions in the capacity of hon. secretary the success of the society Is in a great measure to be attributed. A variety of excellent speeches followed, in the course of which frequent allusions were made to the fact of the grain-growers of the district taking some of the principal prizes, in competition with those of Adelaide and Victoria, at the late show of the Port Phillip Farmers' Society, and all present expressed their satisfaction at the results of the second annual ploughinig match of the " Mornington Branch."
