Inthisstage,then, the melted space is no longer a dome; it assumes the form of a little balloon or roinid bubble of air, surrounding the flower-bud. At the same time, the ice beneath, having frozen again, almost touches the stem, so that the bud seems to occupy a small, clear area of its own in the midst of the sheet, with ice above, below, and all around it (No. 3). You would say that growth under such circum- stances, in almost icy-cold air, was impossibleâbut if you examine the ice-sheet at the edge of the ne've'f you will find it studded by hundreds of such.
