cslaWIsliment where the necessary repairs may be ef- 

 fected. 



The plate of the piston for the Azof Avas moulded 

 with care. The grain of the material shewed that it 

 was of good quality. This observation applies to the 

 clutch box as well as to the other pieces of machinery 

 exhibited. As for the railing, it would perhaps have 

 bettpr not been exhibited, for articles of this nature the 

 moulding of which is indeed a very delicate operation, 

 require intense heat to produce even surfaces. It is 

 probable that the sand used fir moulding this piece 

 was not of the proper kind, it cooling the moult before 

 the mould was filled. Moreover, the moulding of flat 

 ornaments is made with unprepared sand and the ap- 

 pearance of the railing seemed to indicate that kiln 

 diied sand had been used. 



IIoAvever it may be said that the Exhibition of cast- 

 ings was interesting in as much as we just observe, 

 that if shcAved the immense ressources to be derived 

 from the recasting of iron, particularly in the manu- 

 facture of sugar. The Society theiefore thought it fit 

 to award a Medal to Messrs. Barron. 



One or two models of ships Avere exhibited and were 

 deserving commendations for the exactness of their 

 shapes and dimensions. 



Amongst the specimens, results of the application of 

 mechanical arts, Avere shin^^les prepared by the suav- 

 mill, Avhich should be classed among the most interest- 

 ing productions. ' 



The substitution of machinery to manual labour, ex- 

 pensive and difficult to obtain, should certainly be the 

 constant aim of colonial industry. Noav the shingles 

 produced Avere Avorthy of notice on account of their 

 shape, and, perhaps also, on nccount of their price. 

 The application of stCKm to their nianut''acture, must 

 considerably diminish their cost. 



Now, in directing our attention to a scries of models 

 exhibited by Major Martin av.^ sec that he prnposes : 



1. To adopt a chain to bring tlic canes to the rolierS, 



2. An apparatus to skim the pans and empty ihem.
