"I'm afraid I don't know anything about perspective," pleaded Aldred. "I just drew it as I thought it looked. The cottage is so pretty, I felt I simply must paint it." "That is the right spirit. Go on and try, even if you don't always succeed. I am glad to see you make an effort to sketch out-of-doors. There is no teacher like Mother Nature, and the attempt to reproduce a living tree, or a house, on paper will do you more good than a hundred copies. Why did you make the lines of your windows run up, when they so clearly ought to run down?" "I don't quite understand," said Aldred, looking puzzled. "Give me your pencil a moment, and I will show you." "Oh, thank you!" cried Aldred, jumping up with alacrity. "Please take my camp stool, and then you will have exactly the same view as I have. It looks so different when one is sitting down." Mr. Bowden good-naturedly installed himself in Aldred's place, and, taking her paint-box and brushes, began to give her a practical lesson in sketching from nature. "The composition is not bad," he remarked, "but if you had brought in that far tree, which is considerably taller than the cottage, it would have raised the subject on the left-hand side of the picture, and given a pleasanter result. Shall I put in a touch to show you what I mean?" "Oh, please!--as many as you like. It would be such a help to watch you!" replied Aldred. "Very well, then. In the first place, I make the lines of your perspective slope down to their right vanishing point. Is not that better? Now, a dab of brighter blue in the sky, with a raw edge to give the effect of that white cloud. The trees need massing together, with a greater depth of shade to give roundness to them, and a branch just indicated here and there among the foliage. The stubble field needs a tone of richer and warmer yellow, while a few stooks here in the foreground would be the utmost improvement. Look how I am blocking them in, with strong light and shadow, and two or three ears marked definitely at the top, to show against the dark of the hedge beyond. There! Go on working yourself at the field and the distance. Paint moistly, and don't spare your cobalt blue." "It's like magic!" said Aldred, reviewing the improvement in her sketch with immense satisfaction. "I hardly know how to thank you. I'm afraid I've been wasting your time dreadfully." "No matter, if it has helped you," said Mr. Bowden, picking up his sketch-book. "I must go now, though, for I want to catch the effect of the late afternoon light on those marshy pools beyond the cottage. Don't forget the hints I have given you," and with a friendly nod to Keith he walked rapidly away, and was soon out of sight.
