Graft wrapping machines are coming into use in some of the larger nurseries because they economize time and cost and do work said to be superior to hand wrapping. In a circular describing the "Reed-Bell" machine the following passage (condensed) occurs :. FlU. 191—WHIP GRAFTS WITH TOO MUCH CALLUS An account carefully kept during se^'eral weeks of a grafting season shows the machine-wrapped grafts cost, on an average, fi\'e cents a thousand for twine, 11 cents for wrapping, a total of 16 cents a thousand; a saving of 34 cents a thousand o\-er calico wrapping. But what is of more importance, the tension of the thread may be adjusted to wrap the graft so tightly that it may be taken bj^ the root, thrown or shaken without risk of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Kains, M.
