Gravenstein tree, spreading form. With a single exception, in which two trees had particularly good advantages, the growth on the mulched areas was less than on corresponding cultivated plots. On cultivated soil there was little increase in growth from the use of either manure or com- mercial fertilizer; while on the mulched land the growth was noticeably (2 to 5 inches) greater, as a result of adding plant foods. These facts would indicate that there is enough plant food in the soil to produce a fairly satisfactory growth if the mechanical treatment is such as to render it available, and other plants are not allowed to rob the 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 Maine.
