Cream City Dry Arsenate of Lead 
Contains approximately 33% arsenic oxide, therefore has maximum 
killing power. Due to its fineness, is easily and uniformly sprayed, 
sticks longer to the plants and therefore gives the highest efficiency and 
economy. 
Cream City Nitrate of Soda is a fertilizer which gives the plants an 
early start and supplies the necessary nitrogen.

puted fact t'liat if we want fruit 
we must prune. 
The next point to discuss is how 
to prune, merely cutting wood 
from a tree could not be called 
pruning by a professional. In 
pruning a tree, there are several 
important points to consider. As 
everything in the world is limited, 
so is the sap of a tree, therefore 
we must direct the sap to the 
main branches and allow no suck- 
ers to grow on the insides of large 
branches and even if the sucker is 
old enough to bear, for if we do 
we will find fruit on the main 
branches small and if large suck- 
ers are not removed in time 
(which can be 'seen on old trees 
which have not been pruned for 
years) the tips of the main 
branches will not bear at all and 
sometimes even die. 
For my part, I think a great 
deal of the open head pruning. 
By this I mean allow no leaders 
to grow in center of a tree (apple- 
tree) but trim it so it will have the 
shape of an inverted open umbrel- 
la. This allows the free access of 
sunlight and air and also makes 
spraying more simple and 
thorough, in this way the most 
important branches get uniform 
in strength and carry their fruit 
without braces. Others may 
say I am wrong but I tried this 
out and will not go back to the 
leader tree. 
In connection with pruning 
something else comes to my mind 
that may be known to a great 
many treemen, but I have not 
seen an article where anyone made 
it generally known, and that is a 
a handy pruning saw. I use an 
ordinary 18 inch sickle shaped 
saw and take the handle off the 
blade. Then round the edges off 
of a 10 or 12 foot pole using as a 
rule a piece of maple flooring, 
shape it down to two inches, cut 
a slit in one end of this pole the 
thickness of the sawblade and in- 
sert the above mentioned blade in 
this slit, care has to be taken to 
set the blade right in the pole be- 
fore drilling the holes for the riv- 
ets, use the same three rivets to 
fasten the sawblade as were form- 
erly used in the short handle. 
With this saw I never have to

climb into a tree but prune all my 
ti-ees from the ground. Every 
treeman ought to have a saw like 
this; it saves time, makes it much 
more convenient and a person be- 
ing on the ground can also see ex- 
actly what branches to cut away.
