Abstract: Combustion of horizontally-stacked fireplace logs is expedited and facilitated by maintaining the adjacent logs in a spaced-apart relationship, at least until proper combustion of the individual logs has been initiated. This enables the surfaces of the individual logs to rapidly reach combustion temperatures upon exposure to open flames from paper or other burning tinder or exposure to an underlying bed of glowing embers. The spacing of the logs can be readily accomplished by use of spacer devices. Preferred devices are members having a generally Y-shaped configuration in vertical cross-section so that the member has (i) a trunk portion adapted to be interposed in an upright position between two adjacent laterally positioned logs to provide spacing therebetween, and (ii) a pair of upwardly and outwardly extending arms forming an upper surface adapted to support or cradle another such log above, between and spaced from those two laterally positioned logs.
