There is evidence on all sides that the people of Michigan are deeply interested in nut culture. Some have invested in pecan lands in the Far South; no doubt some own Persian (English) walnut, almond or filbert orchards on the Pacific Coast; and others are at the point of planting nut trees in Michigan. Everybody would go nutting in fall if he could. Michigan leads all other northern states in what its institutions and some of its people have done toward developing the nut industry.
Some thirty years ago the Lake Shore and Michigan Southern Railroad Company showed its interest in nut production, when it planted many miles of chestnut trees along its tracks running north from Adrian. Between 1888 and 1892 there were planted on the grounds of the sub-experiment station at South Haven, a number of pecan trees of Iowa and Missouri seed, Japanese walnuts, a number of filbert plants and a collection of almond varieties. At about the same time, Prof L. H. Bailey set out half dozen pecans and Japanese walnut trees on the campus of the Michigan Agricultural College. Later, Professor L. R. Taft added several seedling Persian (English) walnut trees to the group.
In traveling over the southern part of Michigan, one cannot go far without seeing signs of interest in nut trees. Everywhere the black walnut has been spared or planted. In certain sections it is to be found about practically every farm house or at least near enough by to furnish the winter supply of the family nuts. The chestnut is less common in any part of the state than is the black walnut, not appearing to any considerable extent except in the lower southeastern corner. It has not fared well in the state either as a native or planted tree. The Persian or so-called English walnut has attracted considerable attention from time to time, and under especially favorable surroundings one occasionally finds thrifty specimen trees. The pecan, the Japanese walnut, European hazel or more popularly called the "filbert" have all been given limited trials at various times. Even the almond has had a day in Michigan. Quite possibly the pistache has been through the same experience; but if so, the fact is not generally known. That species is from arid Asia and wholly unlikely to succeed in the latitude of Michigan although a young tree of a Chinese species ornamental because of its fine feathery foliage, green in summer but which takes on a brilliant hue in fall is, or was the last we know, doing well on the private grounds of Dr. Robert T. Morris, near Stamford, Conn.
Among the kinds of nut trees from which we can select varieties for planting in Michigan, there are eleven or more distinct species. With such a range as this, one might ask, why not go into nut growing in Michigan on the same scale as in the growing of apples and peaches. There are probably better reasons why this is not being done, but two very good ones are that there are not enough available trees of good varieties to plant more than a single orchard of respectable size in the state; and the other; it would not pay to put good Michigan land to nut trees of such varieties as are now available even though they could be had.
If nut trees can't be had and wouldn't pay if they could then why publish an article on "Nuts for Michigan Planting," is probably what will run through the minds of most readers of these lines. It is certainly a logical question, but there are at least ten reasons why nut trees should be planted in Michigan.
1. The forests of Michigan have reached the point of depletion such that for the sake of future generations, trees of some kind other than fruit must be planted.
2. While planting, we may as well select those capable of performing more than a single service; in other words, trees of maximum possible use. Oaks, poplars, ashes, pines, elms, etc., all have their places, but not one in the group can produce anything of food value to humankind.
3. Nut trees of most kinds, rightly used, are valuable for timber purposes and are very effective in the landscape.
4. Members of the walnut family including the hickories are especially appropriate along the highways and city streets. They are sturdy, long-lived and not easily damaged by storms or neighbor's boys.
5. Nuts are among the very best of the meat substitutes. They contain much of the same food elements as do meats, although in different proportions. Some contain starch and to that extent can be used as are the cereals and Irish potatoes. Nuts are the only vegetable product grown in Michigan, which in raw condition afford a complete and fairly well balanced food for human beings. Every pound of nut food that can be raised from a tree along the street or in the fence corner on the farm is clear gain, and that much added to our national food supply.
6. Nuts are rapidly assuming importance as factors in the lists of American foods.
7. Many species of nut trees are adapted to some parts of Michigan. By planting the best that are now available, and by constantly being on the lookout for better sorts, superior varieties will be certain to develop in a short while, the same as has been the case with all older orchard fruits and farm crops.
8. Whoever intelligently plants nut trees performs a distinct public service. He will receive the gratitude of more than the present generation.
9. Among all kinds of trees, none are more appropriate for memorial purposes to the men who did not come back from France, than is the black walnut. That species itself took a valiant part in warfare. It furnished material for gunstocks the same as in previous wars, but in the World War it rendered what was considered by eminent authority, a greater service in supplying propellors for aeroplanes. The shells of the nuts contributed their part toward the making of carbon for gas masks, and no one knows the extent to which walnut kernels made up the delicacies sent from home to the boys in the trenches. With such a service record as this, the black walnut is entitled to a memorial of its own. Its value as a timber tree, as an ornamental, and as a food producer, together with its great range of adaptability from North to South and East to West, should justly entitle it to recognition as a National tree.
10. Michigan has a law providing for the planting of nut trees along its highways. Thus, the state has officially put its approval on the idea and has become a leader in the encouragement of this great kind of economy and thrift. It has taken a step toward conservation in a direction which is highly developed in certain parts of Europe. The product is sold to the highest bidder and the income used in the upkeep of the road system. In that manner the roadways of those sections take care of themselves. In this country millions of dollars of state and federal moneys are being used this year, (ending June 30, 1921), in the construction and upkeep of public roads.
Desirable as it would be to accomplish these ends, it could not all be done at once. Even though there were an abundance of available trees of tried kinds, it would take a long time to plant them and to care for them until they might become of profitable bearing age, also public opinion would need to be remolded in order to insure their care and protection. Still it can and will be done. The movement is already on; the Michigan law began to operate soon after being passed, and the Division of Forestry at the Agricultural College is raising the trees for planting. Public opinion regarding the care of the trees and their product will take care of itself when the value of the trees and their products becomes apparent. Both in California and in Oregon not only nut but fruit orchards and vineyards, grow beside the roadways with no protection other than that of public opinion; and what has been done in one part of the country can be done in others as well.
The eleven species referred to as being available for Michigan use are as follows: The almond, beechnut, butternut, chestnut, filbert, (hazel), pecan, shagbark hickory, shellbark hickory, black walnut, Japanese walnut, and the Persian or so-called English walnut.
Taking these up in order we will consider first the
