IJT HAS been conclusively proven that dynamite is an exceed- 
ingly valuable aid in the successful growing of trees. Those 
■who have tried it are thoroughly convinced that no method 
of excavating the hole in which to plant a young tree is so 
economical, quick, or productive of desirable cifter-results 
ds blasting with dynamite. 

Sometime ago it was the prevailing idea that dynamite w^as unneces- 
sary for tree planting unless the soil chanced to be underlaid with hard- 
pan, in which case the explosive was regarded as valuable for breaking 
through the hard soil. It has been found by experiment, however, that 
trees thrive better when planted in blasted holes than in hand dug holes, 
even when no hardpan is encountered. 

The explanation of this is simple. It is because the explosion of 
the dynamite loosens up the soil for yards around the spot, kills all 
grubs, worms or other animal life likely to injure the young tree and 
thus makes root growth easy; whereas, digging the hole with tools tends 
to pack the earth around the roots and retard their growth. 

Scientific agriculturists have discovered that water is the most 
important element in all kinds of plant growth. Soil which is of the 
natural consistency to allow water to circulate freely through it and still 
retain or conserve it so that it is available at all times for growing plants, 
may be considered as ideal for agricultural purposes. Few soils possess 
this natural consistency. Other soils, which may be classified as good- 
average, or fair, must have artificial preparation in order to make them 
produce the results that may be expected from the rarely-found perfect 
natural soil. 

Few persons understand the principle of plant growth. It is not 
necessary, as many suppose, that the root of a plant shall come in actual 
contact with all of the plant food elements of the soil needed for the 
sustenance of the plant or tree. Plant roots have the power to draw 
from the surrounding soil the necessary elements of plant food, provid- 
ed the soil is of such a character as to permit the passage of these 
elements through it. Water or moisture is the carrier of these plant 
food elements through the soil and into the plant roots. This will in- 
dicate the importance of a porous soil which will permit the free 
passage of water through it in order that plants growing upon the sur- 
face may be properly nurtured for rapid and healthy growth, and it is 
because the action of an explosive on soil causes it to become thor- 
oughly loosened and aerated that trees planted in blasted holes show 
so much stronger and healthier growth than trees planted under old 


p* yj 

In order to give those who may not understand the subject an idea 
of the scientific principles of plant growth, we will quote Mr. W. J. 
Spillman, Agriculturist in charge of Farm Management Investigations, 
Bureau of Plant Industries, U. S. Department of Agriculture. He says 
in a recent bulletin: 

"Plant food is dissolved in water. While a plant is growing, a 
constant stream of water flows up through it and evaporates at its 
leaves. For every pound of increase in dry matter made by the 
plant, from 300 to 500 pounds of water flow up through it.^ 

"Plants in their growth make use of thirteen elements, nine of 
"which they secure directly from the soil. These are called the 
mineral plant foods. They are phosphorous, potassium, calcium, 
magnesium, sodium, iron, silica, chlorin and sulphur. Soil consists 
mainly of small particles of rock. Nearly all kinds contain more or 
less of these mineral plant foods. Every year the soil w^ater dis- 
solves off a thin surface layer from each particle and plants appro- 
priate this water, thus securing their mineral plant food. Hydrogen, 
another important element of plant food, is also secured from 

"In order to produce a ton of hay on an acre of land, it is neces- 
sary that the growing grass pump up from that ground approxi- 
mately 500 tons of water. In ■ order to supply this enormous 
quantity of water, the soil must notonly be in a condition to absorb 
and hold water well, but must be porous enough to permit water 
to flow freely through it. 

"In addition to acting as a water carrier for plant life, soil must 
permit a proper circulation of air through it. Nearly half of the 
volume of ordinary soils is accupied by air spaces. Soil which be- 
comes so compact as to stop the air passages, is too wet for most 
crops arid needs drainage, for plant roots must be supplied with 
air and the soil must be porous enough to permit of its free circula- 
tion. One of the most important objects of plowing is to loosen up 
the soil and mix fresh air with it." 

Orchardists and nlirserymen who have had long experience in 
planting trees in holes prepared by dynamite blasts, have learned that 
compact subsoil is broken up by the blasts, which enable the land, thus 
made porous, to absorb plenty of water in rainy Weather and store it up 
for the use of growing plants in dry weather. As Mr. Spillman says, 
this water in ascending to the plant roots, carries with it the many 
necessary soluble fertilizing elements.

Few persons realize the depth of tree root expansion. In one of 
the " Farmers' Bulletins " issued by the United States Department of 
Agriculture, is shown a view of a cross section of orchard land which 
we reproduce on the opposite page. Note the scale on the sides, indicat- 
ing that this tree has sent its roots downward 21 feet into the soil. 
This is natural growth. Under normal conditions a healthy tree will 
seek its food in this way; but suppose a layer of hardpan is encountered 
at a depth of five or six feet? The roots must then spread out laterally 
for twenty feet or more. The result of this unnatural sidewise growth 
is that each tree in the orchard is compelled to go over into the feeding 
supply of its neighbor and consequently does not receive the necessary 
amount of plant food to properly nurture it and eJlow of its rapid growth. 
Its yield of fruit is also lessened by this forced encroaching of one tree 
on the feeding ground of its neighbor. Then too, a brief dry spell ex- 
hausts all the moisture from the thin feeding ground of such a tree 
stopping its growth or killing it. 

Dynamite blasting proves a simple and effective remedy for this 
condition. The blast breaks up the hardpan and permits the roots to 
take their natural downward course into the lower strata of soil in 
which plenty of plant food elements are available. Under these con. 
ditions, one tree is not interfered with by another; each one receives the 
benefit of all of the soil allotted to it at the time the surface was meas- 
ured and laid out at planting time. 

It must not be assumed from the above that dynamite blasting is 
beneficial only when the top soil is underlaid with hardpan. It is of the 
utmost importance to assist a tree, especially a young one, to send its 
roots out into its feeding bed as easily and rapidly as possible. The 
more porous and loose the soil, the more rapid will be the growth. 
Even in the loamy soils of Oregon, generally admitted to be the most 
perfect for fruit tree culture found in the United States, blasting has 
proven extremely beneficial in forwarding the growth of young fruit 
trees as is shown in the letter of Orcharc^'-' Pci.viey, which appears on 
page 9 of this booklet. 

The main object to be sought in tree planting, is to so prepare the 
ground that the growing tree can absorb as large a percentage of mois- 
ture as possible from the soil which it occupies. Loosening and aerat- 
ing the soil accomplishes this purpose. A Cornell University authority 
advises that a tree planted in soil properly prepared, can absorb 69% 
of the moisture contained in it.

This Interesting Letter from an Oregon Orchardist, Proves the Efficiency 

and Economy of Dynamite for Tree Planting 

and Cultivating. 

Du Pont Powder Co., Grants Pass, Oregon, May 12, 1911. 

Wilmington, Delavi^are. 

Gentlemen: — In reply to your inquiry as to our success witK orchard trees set in 
dynamited holes, I am sending you photographs of four trees that ans'wer your question. 

Figures 5 and 6 are Bellflower apple trees; Figure 5 -was set in a spade dug hole, and 
Figure 6 in a dynamited hole. 

Figures 7 and 8 are Bing cherry trees; Figure 7 "was set in a spade dug hole, and 
Figure 8 in a dynamited hole. 

These four trees -were part of a shipment of year old nursery stock received and set 
out the latter part of March, 1909. The photographs w^ere taken about the 15th of April, 
1911, two years after setting out, just as they -were coming into leaf. 

Bellflow^er apple tree Figure 6 w^as pinched back in June, 1909, about ten weeks after 
planting. It Tvaa shortened in by removing some two feet of growth from each main lateral 
the following November. In 1910 it had the same treatment. It is a very vigorous tree 
Tvith healthy foliage and fine color. 

Bellflow^er apple tree Figure 5 had as good ground to grow in, but w^as spade set and 
made such small gro'^vth it needed neither pinching back nor pruning. Not a bit of gro'wth, 
not a leaf has been removed from the head of this tree since planting. The trunk ia less than 
a half inch in diameter, while the dynamite set mate to it, tree No. 1, has several branches 
thicker and finer than the trunk of Figure 5. 

The Bing cherry trees. Figures 7 and 8 have the same identical history as Bellflower 
apples Figures 4 and 5, with the exception that w^e did not shorten in at fall pruning Figure 8 
as much as we did apple No. 6. 

We have heavier tops and taller trees of these varieties in the orchard, but these trees 
arc t-wo favorites, very typical of their kind and strike a favorable average for the lot of five 
hundred. From 2S0 apple trees so set 'we got a perfect stand, not one of which is missing 
or replaced. 

V/e use dynamite for making holes in planting trees on our very best and deepest 
ground, as well as the poor spots. It is much cheaper than hand labor; it is much quicker 
when speed is a most important point and delay -will cause the loss of many trees. It insures 
every advantage to the tree getting a good start.

After tne orchard is staked, one man ■with a shovel removes a circle of surface soil 
from ahout the stake, usually five cuts or so, w^hioh is laid to one side to use in filling the 
hole to proper level before setting the tree with the roots carefully pruned back. 

A second man follows the first with a crow bar and w^orks the hole down where the 
stake comes out. If a stone or anything of the sort is encountered -we dig it out. If a spot 
of hard sediment or hardpan is encountered the hole is put through. These holes are about 
eighteen inches deep. We use one stick of dynamite properly fitted with 18 incbes of besl 
fuse for the average hole. It ia dropped to the bottom of the hole, tamped down, then fuse is 
lighted. There is very little stuff thrown up, the force going down and out. The holes are 
allowed to stand probably over night, or part of the next day, are probed with a crow bar, 
and, if satisfactory, the sides are broken in, the top earth at one side filled in, and the hole ia 
ready for the tree. 

We have set all our trees in wet weather, which insures a storage of moisture under 
the tree. If one were compelled to set in dry earth a generous supply of water should be 
added to settle the hole prior to throw^ing on top earth that makes the bed for the tree to set 
on. Twice each spring a circle should be worked up to a fine mulch about the depth of a 
spading fork. This circle of mulch should be kept loose, unbaked and free of weeds the entire 
growing season. 

Last November we had occasion to remove some filler trees. Grimes, Golden apples, 
seven months after setting out, one of which "was spade set. They -were taken up with the 
greatest care so we could get the roots out intact just to prove to ourselves what difference in 
root gro-wth we -would find in sam^e variety, in perfectly matched trees on the same ground. 
from the two methods of sefling. 

The spade set tree had a fine bushy and vigorous tassel of roots about a foot long. 
The dynamiite set tree had two roots going down som,e three feet or over. I held it out at 
arm^s length, my hand clasped around the graft scar, and the roots touched the earth. Also, 
it had a great quantity of medium and short growi:h roots. The difference was so great and 
convincing that we now have thirty acres of new orchard atid every tree is set with dynamite. 

You -will probably be amused at my zeal, but I used half sticks of dynamite in making 
up a rose bed," and also for a hardy border set with peonies and other perennials. Am happy 
to say the peony plants are now ready to bloom profusely their first season, although, hitherto, 
I have failed to bloom them before the second or third year in the new ground. 

^Ve wouldn't undertake to clear ground or set new trees, shade or orchard, 'without 
using dynamite, notwithstanding our soil is a beautiful loam, with little stone in it, and run* 
from five to six feet deep. Yours truly, 



Dynamite Kills Fungus Disease. Makes Trees Grow Twice as Fast. 

Having learned that Mr. James Craig, President of the Rosecliil 
Fruit Farm of Waynesboro, Va., has been using dynamite in the tree 
planting and regeneration work in his extensive orchards for several 
years, we sent an investigator to obtain his views. The following is a 
report of the interview: 

Mr. Craig is a very progressive fruit grower. He is one of the first 
among Eastern orchardists to employ orchard heaters; as a result of 
this enterprise the fruit on his trees was saved in the spring of 1911, 
when a heavy frost killed all other fruit in the neighborhood. Mr. 
Craig has also used dynamite for killing fungus diseases in the ground 
under and around old trees which have died of fungus diseases. As a 
result, he has been able to use the ground for replanting, something 
which has been considered inadvisable previously. 

Our representative obtained a number of photographs of trees on 
Mr. Craig's property, some of which we reproduce in this booklet.

Figure I shows a five year old apple tree planted where an old 
apple tree had died of a fungus disease, which indicates Mr. Craig'a 
success in overcoming this dread disease. 

Figure 1 shows a six year old apple tree planted in ground pre- 
pared by exploding a half cartridge of 40% strength Red Cross Extra 
Dynamite at a depth of eighteen inches. 

Figure 9 shows a view of another tree planted in the same month 
of the same year by the ordinary method of digging a hole with spade 
and pick. By comparing the height of this tree with the man holding 
an eight foot rod in his hand, also shown in each picture, the differ- 
ence in the size of the trees can easily be seen. 

Figure 1 1 shows a nine year old tree planted in ground prepared 
by blasting a half stick of 40% strength Red Cross Dynamite at 
a depth of eighteen inches. Figure 1 2 shows a nine-year old tree 
planted in spade-dug hole. The two trees just referred to, are not 
200 feet apart. 

The soils in both plots shown are practically identical; the trees in 
these orchards are both of the same species of apples; but, as will be 
noted frorh the photographs, the trees planted with dynamite show 
very good growth, whereas the trees which were not planted with 
dynamite show up poorly. 

In February of 1911, Mr. Craig did some blasting in his orchard, 
with a view of loosening up the soil midway between his trees. He 
used in each hole one-half cartridge of 40% Red Cross Extra Dynamite, 
exploded at a depth of eighteen inches. One of the objects of this 
blasting was to break up some shale underlying a great many of the 
trees and preventing the deep growth of the roots. To see what results 
these blasts accomplished, some of the soil was afterwards dug out with 
shovels. It viras discovered that the ground had been broken up at a 
radius of from six- and one-half to eight and one-half feet from the hole 
in which the blast had been discharged, thus giving the tree roots an 
opportuiiity for deeper and more healthy expansion. 

It is generally known that Oregon orchardists enjoy the cream of 
the trade in apples, pears and certain other fruits. There are numerous 
reasons for this; chief among these, probably, is the beautiful coloring 
of the fruit they produce. There is something extremely appetizing and 
attractive about the glorious big red apples sent to the markets by the 
Oregon growers. People are attracted to the fruit stands by this color- 
ing. They are willing to pay double the price of ordinary fruit for an 
apple which thus tempts them. Even the coloring cf fruit may be in- 
fluenced by dynamite blasting. The phosphate, nitrate and potash 
salts, if permitted to lie in the soil insoluble, due to lack of moisture, 
cannot be made use of by the tree; but when the ground is loosened up 
to permit of the free passage of moisture through it, these salts become 
soluble and are then taken up by the roots of the tree, sent to the fruit,

and acting in conjunction with the sun's rays, the fruit is then turned to 
the desired high coloring. An orchard which lacks moisture will pro- 
duce fruit of a pale color. 

An important discovery was recently made by Mr. J. C. Whitten, 
Horticulturist of the University of Missouri. He found that fungus dis- 
eases which attack the roots of apple trees could be controlled or 
prevented by discharging a charge of dynamite in the ground beneath 
a dying apple tree, or under the stump of an old apple tree, or in the 
ground where a stump had stood, allowing it to weather all winter. 
This discovery saves much valuable orchard land, as formerly it was 
impossible to plant an apple tree at a point where an apple tree had 
died, or a peach tree where a peach tree had died of a fungus disease. 

Mr. W. R. MacDonald of Columbus, Kansas, reported that he plant- 
ed 9 peach trees a few years ago to determine positively whether any- 
thing was to be gained by using dynamite. Three of the trees were 
planted in holes made by drilling a two inch auger hole three or four 
feet deep and detonating a charge of explosives in the bottom; and the 
other six were plcinted in holes of the regulation size dug by hand. 
Three years later, the trees which had been planted in the blasted holes 
were stronger and healthier, and produced between five and six bushel? 
of very fine peaches, but the six trees planted in the same ground with- 
out blasting, bore practically no peaches, both fruit and leaves having 
shriveled up and dropped off during the dry season. 

A similar experience was that of Mr. Howard Hester of Colony, 
Kansas, who set out an apple orchard more than twenty years ago. 
After digging holes for a number of the young trees, he bought a case of 
dynamite, some blasting caps, and safety fuse, with which to blast holes 
for the remaining trees. He reports that the trees planted in blasted 
holes are superior in every way to the others, and that they have pro- 
duced better fruit and more of it ever since they began bearing. 

The reason why blasting^between the row^s benefits the trees is that 
it's at ends of roots trees take up moisture and plant food. No mositure; 
no food. During summer little moisture reaches ground Euround trees 
within the foliage area; the foliage deflects it to edge of foliage line, hence, 
trees do not get the moisture they should. Naturally the earth under 
the foliage protected area absorbs it away from end of roots. Hence, 
extra valuable results accrue from subsoiling between row^s. 


St. Clairsville, C, July 10, 1911. 
'We have, this year, used dynamite in planting orchard trees. So far as the season 
has gone under the most unfavorable season in years "we have had most satisfactory results. 
"We intend to plant, this Fall, 500 to 1000 trees in the same way, -which we would not do if 
past trial had not proven a success. "Will report to you again regarding our experience. 
We are. Yours truly, 

Per J. W. Riley.

Arlington Heights Land Company of Riverside, California, have 
used explosives for several years in their orange groves. Mr. James 
Mills, Manager of this Company, has probably had more experience 
along this line than any man in Southern California. His method is to 
put down a hole 5 feet deep between four trees in which the charge ia 
exploded. The shot throws out the rock or hardpan and leaves an 
excavation about 6 feet square and 5 feet deep. This hole is then filled 
with alternate one foot layers of manure and surface soil. 

Mr. Mills advises that on a recent visit of a prominent horticulturist 
connected with the U. S. Department of Agriculture, he opened one of 
these holes to show results. They found a perfect net work of lateral 
roots and feeders, showing that four trees were obtaining nourishment 
from this one hole. The property is now one of the best paying invest- 
ments in California, and the management attributes its success to the 
methods employed. 

Other California orange growers blast between their trees in August, 
September, and October, when the ground becomes so hard and dry 
that it will not absorb moisture. When thoroughly broken up by the 
blasts, the trees, which were formerly wilted, will show new life and 
vigor in from seven to ten days. 

Orchard Dynamited Twenty-one Years Ago. 

A pioneer in tree planting with dyneimite was W. R. Gunnis, of San 
Diego, California, who, some twenty-one years ago, planted an orchard 
in this manner at La Mesa, near San Francisco. It appeeurs that Mr. 
Gunnis observed the necessity for breeiking up hard and impervious 
sub-soils as preliminary to successful tree-planting, and after struggling 
with the cruder method of pick and shovel, finally hit upon the idea of 
using dynamite, thus obtaining the result in view^ at a reduced cost, and 
with a great saving of time and labor. About forty acres were 
planted. The charges of dynamite were exploded in the midst of the 
hard stratum and the trees planted in the holes thus excavated. 

It w^as observed that the orchard matured more rapidly and resisted 
drouth and other unfavorable conditions with marked success. For 
many years this orchard was recognized as one of the most productive 
and best appearing in the neighborhood. Some of the trees are still 
thriving, although the tract has been subdivided and used as residence 

Reviving Failing Trees 

Dyneutnite is also an effective agent in regenerating old orchards. 
A charge of slow acting explosive under or between old trees, loosens 
up the soil and allows more root expansion, besides killing ground 
worms, v^rhich may be injuring the roots. 



Wilmington, Del., June 3, 1911. 

On my farm near Here I have quite a number of grape vines and a year ago I noticed 
at the time the leaves should have all been out that the vines appeared to be dead. The buds 
appeared to be blighted in some way. However, late in the season the leaves finally came out 
but there was no grapes on the vines. Last fall I had a demonstrator on the place doing aome 
subsoil blasting and I had him blast between the rows of grape vines about every 10 feet or 12 
feet along about % of the rows, the balance was left unblasted to see whether there w^ould be 
any difference between the blasted and unblasted. This spring on the vines on the ground 
that was blasted the leaves came out early and grapes formed in abundance while the portion 
that was not blasted was exactly the same as a year ago. It would look as though the blast- 
ing had conserved the moisture during the -winter and made the vines more vigorous and better 
able to overcome the blighting conditions than the portion not blasted. 



E. I. du Pont de Nemours Pjwder Company, Parkersburg. W^. Va., 

Wilmington, Delaware. July 8th, 1911 

Gentlemen: — Our first experience -w^ith dynamite in orchard work ^vas during the 
spring of 1911. Sufficient time has not yet elapsed to demonstrate positively the benefits to 
accrue. The season in this locality has been extremely unfavorable for starting a young 
orchard. The soil has been unsually dry ever since the trees -were planted. 

As "we considered the use of dynamite in the orchard -work in the nature of an experi- 
ment, -we left a number of checks for comparison. ^Ve used dynamite for digging holes for 
planting of apples, pears, quinces, cherries and plums. In all these, the trees 'were planted in 
sod, and the ground -was not broken except with dynamite. In other portions of our orchard 
the same kinds of trees were planted in ground that -^as carefully plowed and has been since 
cultivated several times. There is no decided difference in the trees planted by the t^*'0 
methods. AVhere the trees -were planted in sod, how^ever, without the use of dynamite, from 
sixty to se^enly-fi'Ve per ce?it, are dead. Whereas, where the dynamite was used, the loss ■v.-iW 
not exceed t'WO or three per cent.j and in the cases where the loss occurs, the cause is foreign 
to natural conditions. 

In addition to the large fruits above mentioned, -we have just recently cultivated ■ 
vineyard by putting in small shots of one-third of a stick each, every eight feet in the row. 
We w^ere led to do this after seeing what w^e believe to be decided benefits in its use for 
planting and cultivating apples and other fruits. 

In addition to this, -we used dynamite for cultivating, in a limited 'way, an old orchard. 
The trees in this orchard are from t-wenty to thirty years of age. Up to the present season 
the orchard has been badly neglected. We used one-third of a stick directly under the trunk 
of the tree, about three and one-half feet deep. The explosion did not disrupt the surface, 
but evidently broke up the subsoil and destroyed the old formation -which bound the roots of 
the trees. This was used early in the season before the trees were in bloom. These trees at 
this time show a decided advantage over trees in the same orchard under like conditions, 
which -were not so treated. T\ie ^ro-wth\iaii\>ccn at least t^vtnty-jii'e per cent, i^rtater thty 
are loaded more hen^vily ojuith fruit than the other trees, the fruit is lander sise^^ and the leaves 
and general appearance of the trees indicate a more vigorous thrifty condition. W'e consider 
the use of dynamite in the cultivation of an orchard, as above described, one of the m«st 
beneficial purposes to which its use is adapted. 

Our experience, up to this time, indicates a more extensive U5e of dynamite in the 
future. Its use is both expeditious and economical. Its benctit.t are peculiarly apparent in a 
dry season like this. By its use the roots of the trees are permitted a v^^^-^ter penetration 
than would be possible by any other method, thus, to a certain extent making the tree inde- 
pendent of surface conditions. 

We liifit, approximately t a ton of dynamUe this season, nvithout the slightett .;.././/■«/. 
The men become familiar ^vith its uie and do not consider the labor hazardous. 

Yours truly, 



Woodlake, Cal.. June 30, 1911. 
During the past tKree years we bave set out six hundred acres of lemon and orange 
trees and in every instance have used a stick of your dynamite (Red Cross) in the hole 
where the tree was planted. The trees are aU healthy and doing fine. There is a very 
marked difference between the trees that were set in this manner and those not dynamited. 
In using this dynamite w^e hore a hole three feet with a two inch auger at a cost of 
about two cents per hole, which, w^ith the cost of the dynamite and the labor in exploding 
same for ninety holes per acre is about $6. 00 per acre. There is no other manner which the 
ground can be prepared so well for planting at this cost. 



New Albany, Ind., June 29, 1911. 

Gentlemen: — I used dynamite in planting my orchard of more than four thousand trees 
I used one-third of a stick of 40 % dynamite for each tree. I drilled a hole for each tree 
about t"WO feet deep and tamped the dynamite tightly, exploding each charge -with fuse. The ex- 
plosion loosened the soil -n^ithin a radius of about four feet to a depth of about thirty-six inches. 

"With my long experience of planting trees, I find the use of dynamite the most success- 
ful method. The loosened soil acts as a reservoir to hold moisture. I planted my orchard in 
the spring and find that my loss of dead trees wU not exceed tijo, notwithstanding the fact 
that we have had a six ^cveeks* drouth, this lo'W percentage being due to the loosened soil 
holding moisture. Under no circumstances would I think of planting an orchard wthout 
the use of dynamite. I recommend it as the cheapest, quickest, most successful and most 
satisfactory method.

Mr. A. J. Rider, Secretary of the American Cranberry Grower's' 
Association, of Hammonton, N. J., writes : 

I have used dynamite in the development of my cranberry enterprises with success 
and economy for the past twenty years. In removing obstructions from wat-ir-oourses, 
opening ditches and preparing the way for dams and flood-gates it is especially as rful. _ I 
keep a supply on hand at all times, and my foremen are all instructed in its use. Its saving 
in time and labor thus effected is very great. 

Dynamite will make a straight ditch and under conditions with which nothing but a 
dredging machine could cope. In excavating for flood gates the mud walls are temporarily 
packed so solidly that water hardly seeps through. A crow bar and a stick of dynamite wi 1 
stop a leak in a dam that would otherwise require hours, and possibly days of labor. Ab

Gentlemen: —I am just back from a two weeks stay in our Georgia Orchards. 

While I was there we continued further blasting for the replanting of about 3000 trees 
where they had failed in one of our older orchards. I also looked over carefully the two 
little blocks of trees we planted with dynamite last season and the results are even better 
than 1 had been led to believe when I left there the middle of July. In the meantime 1 am 
becoming further interested in the matter and in the recommendations for renovating some ot 
the old apple orchards in New England and want my clients to try dynamiting a portion of 
the land around these trees, especially when they are m particularly strong heavy soil. 

Yours, J. H. HALE. 

NOTS.— Mr. Hale is the owner of several of the largest commercial orchards in the United States. 



Mr. S. H. Bolinger, President Clear Creek Lamber Company, Shreveport, La., writei 
ua under date of April 26th, 1911, that he used dynamite in blasting the holes in which 1.080 
pecan trees were planted a year ago; also for planting 8,000 peach trees. He says the per- 
centage of loss on the pecan trees (which are among the most difficult to set so that they will 
live) ■was almost nothing compared to the loss on other trees planted in the ordinary vrty. 

Mr. Bolinger explains ho^v the planting w^as done. The soil -wu a hard sand clay 
A 2-inch auger Mrith a long shank was used and a 2-inch hole bored about 4 to 4 }^ f e«t 
deep. In the auger hole one stick of 40% dynamite with fuse attached wai inserted, the hale 
filled and lightly tamped; then exploded. The explosion created a space of about the size of 
an ordinary barrel. The ground was not blown out but -was simply raised on the top about 
3 or 4 inches. In almost every case, hoivever, it could be seen that the ground had been 
thoroughly loosened up for a distance of 10 to 15 feet all around the hole. A post hole digger 
"was then used to bore through the top surface to the vacant space below: the surface soil 
necessary to bore through -was about 10 to 15 inches thick. The top soil was then filled in to 
the depth necessary and the trees planted in the holes, the ground being ^nrell packed around 
the roots. 

It is Mr. Bolinger's opinion that the planting ^ViB successful because the opening up oi 
the soil under the trees by exploding the charge of dynamite created a space for the storage oi 
moisture -which was held throughout the dry spell that followed the planting and thus kept 
the trees alive and in healthy condition. 


Gentlemen; — It may be a surprise to you to learn that I have been using dynamite for 
planting trees for a number of years and have some shade trees planted in that ^vay eighteen 
or tn^enty years ago. They are the finest trees 1 have ever seen grow for their age. In the 
planting of peach trees I gained two years in six; in other words, I got as much fruit from a 
tree planted -witli dynamite at four years eld as we usually get at six years old. 

I not only plant them with it but -n^here a tree is failing and seems to be on the decline, 
I start it off to gro^ong again by firing charges from three to ten feet apart. 

Nothing seems to tickle the earth so much as planting -watermelons after explosion of 
dynamite from three to four feet under ground. I plant Ahem t-wenty feet apart each -way. 
Fertilize heavily and the vines bjar right on until frost, the entire summer. 

Yours very truly, W. W. STEVENS, Orchardist, Mayfield. Ga.

day. Three men could not have done the same amount of -work in a -week. The ground is

Superintendent J. H. Baird, of the famous H iL Georgia Orchard, of Fort Valley, 
Georgia writes under date of May 20th, 1911: 

"The trees planted this se-i<on with dynarait. are growing beautifully and vra have 
not lost any through drouth, while those planted wit'iout dynamite have died out badly and 
show poor growth " 

On June 17. 1911, Mr. Baird again writes; 

"Vegetation ii burning up here for lack of rain, but the young tree have lived beauti- 
fully; do not think we have lost over 2% of those planted wiih dynamite, while ot (he other* 
planted in the old faehioned way \ve have lost from 50^ up." 


Setting Trees With Dynamite to Conserve Moisture 

ARTHUR E. COLE, Prop., High Point Farm and Nursery, Chamblee, Ga. 

Over a large portion of our country is a hard pan, shale or tight clay 
lays near the surface. It is a menace to the productiveness of trees and 
all vegetables which root deeply. The scientific principle involved is the 
inability of such a sub-soil to absorb, retain and give back to growing 
crops the essential moisture. On such land, the water soaking through 
a thin top soil fails to penetrate and finds a second drainage on this sub- 
surface, draining off in "Wet Weather Springs'' or standing in surface 
suspense as " Bogs." Land in this physical condition fails of an agricul- 
cultural dividend. Put in proper physical condition this same land 
becomes highly profitable. The way to proceed is by using dynamite. 
Probably no process of plowing known to agriculture can produce 
the good results in breaking up a tight sub-soil as does this blasting with 
Du Pont Dynamite. 

Planters of clover and alfalfa know this by experiment. Orchard- 
ists have come to accept it as final. Strawberries and all crops requir- 
ing a great amount of moisture respond to its use in a way almost unbe- 
lievable. Short lived crops like tomatoes and cucumbers will continue 
to bear through the long season where the hills are shot with cartridges 
of dynamite. Figs produce a crop the first year after being set where 
dynamited. The writer can see this from his back door as he writes. 
This new-found process is the foundation of a new era in agriculture 
and horticulture. It is the horticultural application that this article aims 
to empheisize. 

At the present time many thousands of trees are being set in young 
orchards all over the United States. Such a boom in apple and pecan 
planting was never before known. It is a logical answer to an unsup- 
plied demand. The question is. will these orchards endure, — will they 
pay ? The answer rests largely with the mode of setting. 

In orchard setting, the use of dynamite is advised in practically all 
soils. The pecan naturally flourishes on the deep, moist, alluvial soil of 
river and creek bottoms. Nature has put it where it will not suffer from 
drought in the' long, hot, dry summer and autumn through which it must 
hold and mature its late fruit. We can move it to our grove or back 
yard and succeed with it by conserving the moisture by dynamiting the 

The method of dynamiting follows under discussion of apples. 

Watermelons and peaches should be dynamited because they require 
great moistvue. being fruits composed largely of water, but of all fruits 
demanding an unfailing and continuous supply of moisture the apple and 
pecan lead. Therefore, it is imperative that we dynamite as an artificial 
means of conserving the moisture. Unlike all other fruit, the apple 
grows on the end of a twig of new wood, a twig which bears no more. 
The apple being a bi-annual, sets its fruit bud for next year during July 
and August of this year. So we see this hard condition imposed: a win- 
ter apple must make its new growth of wood, hold its foilage, mature 
its present crop of fruit, and, if it is to produce again next year, the 
little tender twig bearing an apple must mature a new fruit spur or twig 
along side of it to bring forth a healthy fruit bud next year. And all 
this during a long, hot summer or autumn. The demand for moisture is 
enormous. „ 

What if the tree is shallow set ? What if the roots trail along close 
to the dry surface ? What if the tree is on a dry ridge or hill-side baked 
by the summer sun ? What if on thin land, starved for both fertility and 
moisture ? The answer may be total failure or partial failure and short 
lived trees, or a partial crop, or a crop only every other year, or a large 
per cent, of drops, or defoilated trees. READER! Observe and maik 
well. Your orchard dividend and its future success is in balance when 
you set your orchard. Remember you can never set it over the second 
time. No amount of regrets can retrieve a mistake made in the setting. 
You will spend much money bringing your orchard to a high standard 
by the allotted time for it to begin to bear, but no amount of money 
expended in after years can correct a mistake at planting time. You 
may have in mind plowing out a deep furrow for your row, but remem- 
ber that that furrow can never be plowed again, and the root system 
will be influenced to confine its growth to the small amount of pulverized 
soil. Holes may be dug, broad and deep, but like a large plant in a 
small pot, the hard walls of the hole when filled with roots will cramp 
or turn back or callous. In either of these methods, the orchjird dividend 
will be found wanting. 

The nevyr and eminently successful mode of land preparation for 
all fruit or ornamental trees and for many field or garden crops, 
especially in tight, dry soils, is by blasting holes with -J- cartridge of Red 
Cross 40% Extra Dynamite or blasting the furrow with a like amount 
at intervals of 1 5 to 20 feet. If in a large orchard or a large field, a 
battery may be used to discharge caps. If only a few trees are to be set, 
the blasting should be done with fuse and blasting caps. Let the depth 
of the holes for setting your cartridges be governed by the state of the 
soil. Make a hole with auger, sharpened wood dibber, or crowbar well 
down into the subsoil. Tamp v»rell with moist clay. For the best results, 
throw out a bushel or more of the clay that has been broken by the 
shot and fill w^ith some organic matter that will slowly decompose as the 
years go by mixing and cutting in well with a sharp shovel or spade. 
Leaf mold, woods top soil, fence corner settlings, old bones, scrapings 
from under an old house or out house or any such matter is good. Now 
the tap root can go down and out in an area broken and pulverized for 
many feet on all sides. The tree will make a rapid and healthy growth 
and come to bearing earlier and live many years longer. It will produce 
fruit annually, more fruit, larger fruit and fruit of better color because of 
the conserved moisture. It will resist drought. The much talked of 
" insect resisting tree," is not a tree immune from insects, but a tree 
healthy and vigorous enough to overcome their baneful attack. 

The writer set an apple orchard last winter using Red Cross 40% 
Dynamite, in an area where wooly aphis is known to abound ; but not a 
single evidence of their presence has been noted. This is a reverse of 
every instance of a young orchard in that section, set in the old way. 

The winter, spring and summer just past is one of the dryest on 
record for Georgia. Many trees, in fact a large per cent, of trees, set 
by the ordinary method have died. But in three orchards set by the 
writer with dynamite, 100% are living and doing well. As a neighbor- 
ing nursery man expressed it, "These trees didn't know it had not 

It is to be hoped that in tree setting, we have learned ' That a stick 
in time saves nine." 


Why We Recommend Red Gross Dynamite 
For Farm-work 

Red Cross Dynamite is better suited for the different kinds of 
blasting necessary about the farm, than any other explosive. Our many 
years of experience in the manufacture and use of explosives, has taught 
us that if an explosive is to do its work at the lowest possible cost and 
produce the best results, it must be made with qualities especially suited 
to the work in which it is to be used. Red Cross Dynamite is particu- 
larly strong in those qualities necessary in agricultural blasting. 

Red Cross Dynamite is safer to handle and use in farm work than 
other dynamite. A large majority of the accidents which happen when 
dynamite is used, occur in thawing it. Most dynamite freezes at » 
temperature ranging between 40° and 45° F., but Red Cross Dynamite 
can be depended on to keep soft and in good condition in any temper- 
ature that will not freeze water. When Red Cross^Dynamite is frozen, 
it can be thawed simply by burying the case containing the dynamite 
in a manure pile until the cartridge becomes soft. 

When dynamite is frozen or even chilled, it cannot be properly ex- 
ploded, and consequently does poor work. Most dynamite except 
Red Cross Dynamite, will chill and lose value in a very few min- 
utes in cold Weather. Even when loaded in cold earth or rock 
it will chill in a very few minutes. This loss does not happen with 
Red Cross Dynamite because it will remain in perfect w^orking con- 
dition for some little time, even in freezing weather, and it does 
not lose any power at all after it has been loaded in bore holes below 
the frost line. 

Red Cross Dynamite is also less expensive than other dynamites. 

Red Cross Dynamite is made in the following grades and strengths: 
Red Cross Dynamite, 20 to 60 per cent.; and Red Cross Extra Dynamite, 
25 to 60 per cent. Because it is safest to handle and costs least, we 
especially recommend Red Cross Extra Dynamite particularly for all 
blasting about the farm, unless the work is very wet, in which case Red 
Cross should be used. The only work about the farm for which 
Red Cross Dynamite is not suitable, is ditch blasting in wet ground with 
blasting caps and fuze in the middle hole only. In this work 50 or 60 
per cent. Atlas or Hercules Dynamite should be used and the blasting 
should be done in warm weather. 



Safe Handling of Dynamite. 

There is a popular misconception of dynamite in the public mind. 
Newspapers in reporting outrages such as bomb throwing by anarchists, 
safe cracking "jobs" by burglars, etc., incorrectly report them as per- 
petrated with "Dynamite." The result is an erroneous, widespread 
impression that a dynamite cartridge will explode if dropped on the 
ground or thrown against the body of a person. 

As a matter of fact, safe breakers and bomb throwers do not use 
dynamite cartridges at all; they would not be suitable for their purpose 
because it is so difficult to explode them. What these criminals use as a 
rule is nitro-glycerin. This dangerous explosive is used commercially 
for shooting oil w^ells, etc. 

True there is a certain proportion of nitro-glycerin in dynamite 
cartridges, but the dangerous explosive is scientifically compounded 
with wood meal, and some other ingredients in such a way that it can be 
absolutely depended upon not to explode accidentally if our simple and 
plain instructions for its use are complied with. 

One of the safest of explosives manufactured by the Du Pont 
Powder Company is Red Cross Dynamite, which is especially recom- 
mended for agricultural purposes. This brand of dynamite, in prac- 
tice, is exploded by powerful shock such as is produced by a strong 
blasting cap or an electric fuze. 

Responsible people can use and handle dynamite just as safely as 
they can handle gasoline, matches, or coal oil. The energy of dynamite 
can be directed in the work to which it is adapted just as well as the 
energy of steam can be directed in the work for which it is used.

IF the foregoing pages have convinced you that possibly explosives 
can be used to advantage on your farm, the next questions that will 
arise in your mind are: How are they used ? What do they cost ? 
What quantities are needed ? What other supplies or apparatus are 
needed, etc ? All these things arc fully and clearly explained in our 
large booklet, "The Farmer's Handbook of Explosives," which may be 
obtained, free of charge, by cutting out and mailing card No. 1 printed 
on the inside back cover of this pamphlet. 

We believe that when you have read the book, you will understand 
how simple, safe and economical the use of Red Cross Oynamite is, 
and that you will find many ways to save and make money with its aid.
