Sometimes this material is as fine as pulverized lime- stone, but more often it is rather coarse, and hence slow acting. Magnesian limestone in general is equally as good as pure limestone for liming. Pulverized limestone is considered best to use on sandy 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 Weir, Wilbert Walter, 1882-.
