The accompanying figure represents a fruit ladder which I think about as convenient as any I have seen. The figure shows for itself and the ladder may be made of dimensions required and of any materials which are light and strong, but we use cedar poles. Take a good straight pole say fifteen feet long and four inches diameter at the base, and bore holes for the rounds; then with a saw split to within three feet of top and spread the base to three feet; then put in rounds of good strong oak and secure all in place by proper fastenings and you have a ladder with breadth of base sufficient to stand firm and a single point at top, which we find very convenient.
