Before we embark on the subject of landscape—for our horizon is broadening rapidly—we might spend a few moments discussing the sketching of ruined castles and old houses, which so often form an excuse for an excursion or a picnic, and of which we usually desire to carry home some little momento in the shape of a sketch.
Do not attempt complicated subjects.
If the ruin is large and there are many turrets, many towers, flights of steps, and long passages, choose a modest fragment.
An angle of a wall against which twist the bony stems of ivy, one little window framing a patch of blue sky, a morsel of broken masrony, or a few steps—any of these will give you the materials you need.
