In reading the past reports of this Association, I find one thing

lacking. One becomes interested in a report dated, let us say, 10 or 20

years ago, which contains an account of a project then started. It had

great possibilities. What was the outcome? We do not know. No mention of

it has appeared since. Did it fail? Let us say it did. Why? The answer

to this final query is almost, if not quite, as important as would be an

account of the means employed to make it successful--if it succeeded.

I should like to know, for example, whether anything remains of the

Neilson-Post project in Michigan and what its history has been. I should

like to hear more, also, about the outcome of many of Mr. Gerardi's

intensely interesting and original experiments, such as his method,

described in the 29th Annual Report, of asexual propagation of heartnut

trees on their own roots; or his method of artificially creating

beautifully marked burls on black walnut logs by systematically and

repeatedly scoring the bark. These and many others. Which experiments

were successful and which were not? Mr. Gerardi's original and

adventurous mind is the sort that should be probed for the benefit of

those who come after us.

My report today is my own short and tentative contribution to such a

resume.

In the 1938 Report, on page 73, you will find my ambitious and

optimistic "Farm Plan for Nut Tree Planting." In it I tried to outline a

plan which could be used by any practical farmer with but slight

sacrifice of useful land. Its last sentence reads as follows: "Meantime,

I shall have kept practically all my land in profitable use all the

time." Well, that depends upon what is interpreted as "profitable use."

Tree growth is surely profitable.

The plan, in substance, was as follows: First, plant 20 acres in a

modified forest formation to selected seed, mostly black walnut, the

trees to stand 8 feet apart in rows 22 feet apart. Use the space between

the rows first for truck gardening and later for an interplanted row of

some fast-growing species for timber. No grazing permitted. Second,

plant another 20 acres to a nut orchard using grafted trees of named

varieties spaced 80 feet apart. Protect from livestock and permit

grazing. Finally, plant seed in another 30 acres, spaced 80 feet apart,

the seedlings to be eventually topworked to the wood of promising

discoveries from the first plot. Protect and cultivate or graze.

What has been the outcome of this plan to date? The proposed plan worked

very well in a 20-acre plot where a meadow was planted to an orchard of

grafted trees, mostly pecans and Carpathians, which were protected by

cattle guards, but was not completed in the seedling 20-acre plantation

where the trees stood 8 feet apart in rows 22 feet apart. No grazing was

permitted there, but berries and truck crops were put out. I couldn't

keep it up. The reason: a World War, and lack of help for the intensive

type of farming required for the project. Finally, when I attempted to

interplant the rows with fast-growing trees, weeds choked out most of

them in spite of my own efforts. My own physical and time limitations

defeated me in the interplanting undertaking.

This leads up to an enumeration of my mistakes. First, I did not start

early enough in life. The elements of health and strength have their

part in success. Then, too, let us see what might have been the result

if I had started at the age of 20. Remember, in this first tract of 20

acres I planned a forest plantation of selected black walnut seedlings,

some chosen for nut quality and some for large, straight timber growth.

A tract of 20 acres planted 8 x 8 x 22 feet will hold about 4500 trees.

Allow for thinning and other reductions. If only 1250 trees should reach

log size in 50 years, that is, by today for me, at an average of $50

each, they would come to $62,500--a very tidy estate.

Just now there are perhaps 2500 well grown trees in the good portion of

the ground in this 20 acres. Pleasantly enough, they do not now seem to

need the interplanting of faster-growing trees in order to develop

upright growth but are pushing each other up as they stand, 8 x 8 x 22

feet apart. In this planting, then, there is evidence of successful

timber growth in the good ground but of almost complete failure in the

poor ground.

Another failure is to be noted in my original plan for cattle guards.

These guards were 12 feet in diameter, and about 6 feet in height. These

were satisfactory for sheep after I had installed pipe for posts, but

not for cattle. Trees grow horizontally as well as vertically. Cattle,

reaching for these side shoots, reached over the guards and pushed in

and under. I later reduced the guards to a 6-foot diameter of stronger

woven fence-wire with 6-inch stays, not 12-inch, and raised the height

to not less than 10 feet. The cattle may now nibble off the side shoots

if they wish but the vertical growth is protected. Above 10 feet the

trees can spread out without danger.

Others say, "Permit no grazing at all." This statement, I think, should

be made with certain qualifications. Where bluegrass bottom is used for

the orchard planting of pecans or black walnuts, there is a possible

slight reduction in growth from lack of cultivation, but this loss will

be nowhere nearly proportionate to a farmer's loss of pasturage. And

even in my 8 x 8 x 22-foot planting of seedlings, though no grazing was

permitted while the trees were young, now the older trees are large and

strong enough in the good soil to take care of themselves. Some lower

branches are rubbed off but they should be off anyhow. Also, thank

heaven, the weeds are at last kept down by grazing, the grass is

utilized and, most important of all, the hazard of grass fires is

entirely wiped out. I know of a neighbor's planting destroyed in this

way and I shall always fear fire. I should not permit grazing in a

general purpose woods lot where young growth is constantly coming on.

Failure three: I have failed completely to interest my tenant in my

project. Each mowing or clean-up job is just a chore to him. I can't

blame him. Why should I expect anything else? With a World War on hand,

and with his son in the army, and with two farms to care for, the

immediate bread-and-butter jobs come first and my mowing suffers.

However, the wonderful trees somehow continue to grow in spite of weeds

and wars, perhaps a bit more slowly than they otherwise might, but I am

in no hurry.

The last war casualty was my original plan to make a further orchard

planting of seedlings in loco, ready to be top-worked to the wood of

some outstanding find among the selected seedlings. It has not been

done--period.

I think I do have one or two rather outstanding nuts among the

seedlings, but this leads up to another casualty which must be faced by

all of us--a temporary one, fortunately, namely, crop failures due to

the weather. The larger trees began to bear at age seven. Then, three

years ago we had a drouth. For the two years since then, we have had

summer in March and winter in May. The catkins were mostly killed and

the pistillate bloom was delayed in growth upon the new wood until most

of it came too late for even such pollination as was so sparingly

available. Thus we have had no generally good nut producing season for

three years in our part of Ohio. As a result, my truly outstanding nut

is still in hiding, and I am waiting for a good season to bring it out.

Another disappointment with me has been the Carpathians. They partially

winter-kill each winter. Their trunks still live and send up shoots. I

let them stand, hoping for an eventual hardening of the wood. I regard

them not as failures but as not yet proven.

For purely experimental purposes I planted apple and peach trees close

up to the walnuts. Whichever won out was to stay. Both are there yet.

There is as yet no sign of the results of toxicity. They stand,

literally, arm in arm.

One success I feel may safely be chalked up. In selecting seed for my

original planting, some were chosen for better nuts, as stated, and some

because of the magnificent growth of the parent trees. One such tree

gave me seedlings that are definitely superior in growth to other trees

which stand in equally good soil--in fact, in adjoining rows. This is

noteworthy.

As for the seed selected for nut quality, because of the three poor

producing seasons now past, the result is not so apparent. I can only

say that, out of some score or more sources, the nuts produced upon such

seedlings as have fruited tend to resemble the qualities of their

parents. They all show some variations. Each nut tree is a new

individual but with a family inheritance strongly enough marked to make

the planting of seedlings, when done in large quantities, from the best

parents, a sort of gamble in which the percentage is in favor of the

gambler--which is, as you should know, unusual.

One utterly complete failure must be noted. I shall never again plant a

black walnut seed or tree in any but good soil. Even the best

inheritance cannot prevail against hardpan or worn-out soil.

I was unfortunate, when I made my first and largest planting of seed, in

not knowing about the Northern Nut Growers Association. So I advertised

for local nuts, paying double for the seed I accepted. So far as the

seed which was selected because of the timber growth of the parent tree

was concerned, I am well satisfied. But nut quality was only fair; far

below the quality of our named varieties. Then, through the fine

missionary work of Harry Weber, I was introduced to the NNGA. All my

replanting since then has been from seed bought from the member's

plantations. Next year I expect some of them to come into bearing.

Most of you are chiefly interested in grafted or budded trees, and this

is as it should be. Where sure results and the best possible nuts are

the aim, one would be utterly foolish to plant a seedling. Upon the

other hand, where plantings are made in great quantities, as is the case

with foresters, state or federal agencies, colleges and other

institutions--and with occasional individuals like myself who find their

greatest interest in this particular exciting gamble, I think it is

fairly well demonstrated that the percentage of success can be turned in

favor of the planter by intelligent selection.

But where can the best seed be found? The answer is as plain as the nose

on your face. The best possible source is in existing plantations of

named, proven varieties. As a farmer, I should not use a cross-roads

maverick when I can use a registered Jersey, Hereford or Angus. As a

planter of black walnuts, or any other nuts, either for timber or wood,

I should not pick up my seed haphazardly from cross-roads trees. Every

nut produced by planters of orchards of the best named varieties should

be in active demand by state and national agencies for their own

plantings, and the seedlings from them should be available for the

widest distribution to the public. This urgent demand for better seed

will make existing plantations of proved varieties more profitable and

will fill our forests and farms with far better trees.
