The 1908 product was heavierand apparently better than much of that received during 1909 underthe name of asphalt oil A. The first table shows the analyses ofthe fluxing oil, so called, while the second shows the analyses of theasphalt oil A, so called. Many samples of asphalt oil A frothedwhen heated to 100° C, while this was not observed in any of the11 samples of fluxing oil examined during 1908. Fluxing Oil. [11 samples.].

These 2samples were much thinner than those received this year, and thosereceived late in 1909 were generally heavier and thicker than thosereceived earlier in the season, this being due apparently to the effortsof the company to sell a product within the Highway Commissionsspecifications.
