The trains kept tho time, and pressure was regularly maintained. 
These experiments therefore go to show that native coal, though it be not off 
the first quality, serves to satisfy the necessities of our industry and thereby 
constitutes a great and useful wealth for our country. 
Not content with these results, however, I thought it desirable to accede to 
the request of Messrs. Norton, Megaw & Co., representatives here of the Baldwin 
Locomotive Works, and accordingly sent samples of the Santa Catharina and Rio 
Grande do Sul coal to their Works for further trials, which were the more ne. 
cessary because from the composition and nature of this coal it had been reco- 
gnized here that alterations were desirable both to the fire bars and smoke boxes 
of the locomotives, 
The following is the opinion which the Baldwin Locomotive Works sends us. 
«With reference to the two samples of coal from Santa Catharina and Rio 
Grande do Sul respectively, we have to say that analyses in our laboratory give 
the following results:

Observations.— The coal cakes on the bars. The Santa Catharina has the 
greater heating value but at the same time has the greater tendency to cake. 
In any case, however, there is not suficient difference between the samples to 
render two kinds of boilers necessary for using both of them with success». 
The Baldwin Locomotive Works afterwards submitted specifications of a 
locomotive adapted for the employment of native coal; an engine of 740 horse 
power with a speed of 25 miles por hour and capable of developing a traction 
force of 11,100 Ibs. or 5,095 kilograms. 
The modifications presented refer especially to the fire bars and smoke box. 
The Company state: The fire bars should be of the «finger» type so as to break the 
cake, 
The «:fingers{> should be about 8 inches long and there should be the 
greatest possible space between them, as the coal is in large lumps. The smoke 
box should be fitted with a low escapement ; this is essential, as otherwise the 
locomotive will not make steam. 
The Baldwin Company added the following, which those aware of the stan- 
ding of that Company regard as very important, viz: — «In conformity with the 
above conditions, we are able to construct locomotives for the successful use of 
the coal as per sample sent.»
