| April 30, 1827 | 19 | 12 ¾ | On the 8th of May, an attempt was made to alter the dimensions of the Akaira, and had it escaped detection a few days longer it would have occasioned a failure; as it not only diminished the produce of the furnaces but the massets contained so much impurity that the produce of malleable iron became greater. |

| " 14, " | 21 ¼ | 12 ¾ | The effect of the hot weather became very perceptible in June, and I found it expedient to discontinue smelting on the 7th of that month, but in order to satisfy myself that there was no trick in the diminution of produce, I gave ore and charcoal to the bellowsman to smelt for their own benefit; they tried their best to obtain as much as they could and they got 13, 14, 14¾ and 18—the mean of which is 15—about the same quantity as they got for me. I was, therefore, satisfied that the diminution of produce was owing to the heat of the weather alone as the thermometer ranged from 120° to 122° in the sun, and from 108° to 110° in the shade. |
