LET US LAY hold of frienship. In the eternal life shall we not have friends forevermore? I used to think that friendship meant happiness: I have learned that it means discipline. Seek how we may, we shall never find a friend without faults, imperfections, traits and ways that vex, grieve or annoy us. Strive as we will, we our­ selves can never fully fulfill the ideal of us that is in our friend's mind: we inevitably come short of it. Yet let us not give U!J friendship, though we have found this true. To have a friend is to have a solemn and tender education of. soul from day to day. A friend gives us confidence for life. A friend makes us outdo ourselves. A friend remembers us when we have forgotten ourselves, or neglected ourselves; he takes loving heed of our health, our worlc, our aims, our plans. A friend may praise us, aiul we are not embarrassed; he may rebuke us, aiul we are not angered. If he be silent, we understaiul. It takes a great soul to be a true friend - a larse, catholic, steadfast aiul loving spirit. One must forgi";e much, forget much, forbear much. It costs to he a friend, or to have a friend: there is nothing else in life, except motherhood, that costs so much. 11 not only costs time, ajjection, strength, patience, love,-sometimes a man must even lay down his life for his friends. There is no true friendship withou: self-abnegation, self-sacrifice.

Let us be slow to make friends, but, having once made them, let us pray that neither life nor death, misunderstanding, distance nor doubt may ever come between us, let us be self-possessed in friendship. There are so many ways of grieving a friend,-shall we not walk softly before him? Let us be true to friends, and then believe that they are aiul ever will be true to us.

True love never nags it trusts. One of the dearest thoughts to me is this,-that a real friend will nei•er get away from me, or try to. Love does not have to be tethered, either in time or eternity.

This year's observance of Arbor Week provides us with an excellent opportunity to bring into focus the value of trees to our daily lives and the urgent need of preserving our nation's forest wealth.

Our forests constitute one of the greatest natural treasures of our nation, a treasure we can translate into economic benefits for our people. Among others, they help provide food, fuel and shelter for our people. For this reason, I appeal to our people to take the steps necessary for conserving this treasae of ours in order that we and those to come after us will always be able to avail of the blessings offered by our forests. tQ(I I ., j ""~ --/

OFFICE OF THE PRESIDENT

MESSAGE

It is a pleasure to greet the staff and readers of Forestry Leaves on the occasion of Arbor Week.

The occasion should recall the pertinence of the proper means of guaranteeing the natural resources of the nation through scJ.entific techniques and attitudes.

The wealth of the nation needs conservation, development, and exploitation; and these tasks are for all generations to assume since we must maintain the national independence through economic strength that is both progressive and consistent. Consequently, we need a vehicle that could disseminate valid attitudes towards our national wealth, in this particular instance, the national wealth that is to be derived from the reserve, as it were, of our natural resources.

It is a happy fact that the College of Forestry, University of the Philippines, has precisely this vehicle in the Forestry Leaves. Its mission is to continue to function as a medium of thoughtful discussion of the proper means of increasing our national wealth. As tar as I remember, Arbor Week which used to be ob­ served only tor one day has been celebrated since I was a little boy. And I do not recall any single celeoration which is worthwhile reaeabering.

!his is a sad commentary on the attitude of the bulk ot our citizenry towards the importance ot forest resources in the na­ tional economy. We mark Arbor Week with gestures thnt are empty. Liter&r7 programs are held in public schools which usually turn out to be occasions for showing off histrionic abilities, Some govern­ ment officials and civic organizations sponsor tree planting rites with eyes not on the seedling being planted but on the camera. Ins­ tead ot looking after the seedlings planted, they look long with utmost delight at the pictures published in the IIl!Wspapers.

!he obsession of the administration under President Maca- pagal is the achievement of positive results. Our President himself has strongly advocated the effective protection, proper conservation and wise utilization of the forests. Porest conservation and reforesta­ tion are among the five projects under his socio-economic program.

In the Bureau of Porestry, I have started a massive program of accelerating action on forest protection and conservation anchored on active public cooperation. No effort on the part of the government can succeed if there is no support and cooperation on the part of the public.

Let us, therefore, aake this year's Arbor Week more mean­ ingful by making every day a forest protection and conservation day. Let us make it a life-time concern. It is everybody's concern.

MESSAGE

Arbor Week observance which falls from July 19 to 25 this year, has always been an occasion to inculcate upon the minds of the youth the love of trees and to remind the adults that trees are essential to the well-being of the nation. No matter for what purpose - whether for aesthetic, comfort, protection or economic, trees are sound investment.

The country has now a backlog of more than 1. 4 million hectares and every year thousands of hectares of virgin forests are made bare by kaifigin-making, indiscriminate logging and other illegal clearings in the forests. Reforest­ ation, due to lack of funds, cannot even catch up with the annual forest destruction; and because of this, the people should help the government stop the rampant forest destruc­ tion and plant the idle lands with trees to minimize the occurrence of floods and erosion during rainy season and lack of water during dry season. Forested mountainsides do not only enhance the growth of agriculture and industries but also make the Philippines a healthier and better place to live in.

In this year's Arbor Week, I appeal to the people espe­ cially to those residing near forest lands to rally behind the government's efforts to conserve the forests and restore the utility of bare lands through reforestation.

V. Wood Wastes are classified under the following categories:

1. Logging (forest) wastes - (Usable tops and branches, log trims, and stumps etc.) 15% based on the standing timber.

2. Sawmill wastes - (sawdust, edgings, trims, slabs, barks, etc.) ______50%

The waste items mentioned above are broken down into: a. Sawdust ______47% b. edgings ______24% c. trims 11% d. slabs ______11% e. bark ______7% (Source - FPRI's studies)

3. Veneer mill waste - bucking waste, cutting waste and clipping waste. These are broken down into: a. Bucking waste ______10.23 b. Rounding waste ______15.6% c. Cutting waste ______12.0% d. Clipping waste ______3.2% e. Drying waste ______3 % (Source - FPRI's studies)

VI. Based on the 1962 Log Production, the different waste categories and their corresponding volumes are as follows: 1. Forest residues 506,668,230 bd. ft. - 55% 2. Sawmill wastes 230,701,478 25% 3. Veneer mill wastes ______33,244,000 5% 4. Plywood mill wastes ______118,775,503 12% 5. Furniture plants and other se- condary processing plants __ _ 24,646,433 3%

Total residues ______914,035,644 100%

Gioe Arbor Day Its True Meaning

Every year we celebrate Arbor Day. Whoever initiated it must have been moved by his sense of responsibility to conserve the nation's most valuable resources, the forest. Arbor Day is very significant. It is a day set aside, dedicated by the nation to instill into the minds of the youths of the land the indispensable role which trees play in the comfort, prosperity, progress and existence of our people. But it seems that its significance has not yet reached the understanding of the masses. We have been com memorating Arbor Day since 1906 but we ftai:e not yet succeeded in inculcating in the people's mind the essence of the day. Proof of this is the growing rate of forest des­ truction. There is a need to intensify our campaign to generate forest consciousness among the masses. Arbor Day is the best time to do this for it is on this day when people become somewhat aware of our trees. That little flame of awareness must be made bright· er immediately and its light never allowed to dim so that we can succeed in our goal of disseminating forest consciousness among the people. The main features o.f the annual celebration are the planting of trees and programs which will feature multiple benefits rendered by them as well as our obligations to them. But, let us not confine ourselves to this features alone. The celebration of Arbor Dav must serve as a nucleus for a greater and more intensive program to arouse the interest of the people in the conservation and utilization o_f our forests. Arbor Day comes only once a year. In celebrating this year's Arbor Day let us not lose sight of its scope and significance. Let us give this year's Arbor Day its true meaning. Let us not only plan! trees but also give them the care and the love that they badly need from day to day. - A Duldulao SAVE THE TREES

About one-third of the ornamental trees along the streets of Greater Manila u:ere downed by the typhoon. The loss would be complete were it not for the efforts being made to replant the uprooted trees. The authorities are to be commended for this sal­ vaging operation. It is hoped that as many trees as possible can be saved in this way. The product of many years of care would be wasted if the job is not done fast enough. Almost unnoticed, the tree-planting program has been going on for some years not only in the Manila area but also along the highways leading out of the city to the pro­ vinces. Perhaps the destruction o_f so many trees by the typhoon has made enough peo­ ple conscious of their value to make the puhlic feel more concerned about trees from now on. Certainlv. the authorities themselves could show more interest in trees. Then the vandalism th~t has resulted in the disfiguring of ornamental trees along the Central Luzon highway to Baguio would be easier to stop. Many motorists ond commuters have noticed the destruction caused by wood gath­ erers tvho break of.f whole branches without the least compunction. Some of the destruc­ tion also is caused by mischief makers who gash tree trunks for the dubious fun of it. The coming celebration of Arbor Week, July 19-25, should be a time for arousing pub­ lic consciousness against such senseless destruction. If civic persuasion fails, it will be time to take sterner measures. (Editorial -- Manila Times July 3, '64)

ARBOR WEEK ISSUE--1964 Page 103 THIS KAINGIN PROBLEM

When soil erodes, flood comes and drought waits - and all wildlife, the trees and all the blessings man derives from the forest are in danger. In the Philippines, a form of shifting agriculture known as kaingin is causing des­ truction to the forest at an almost unbelievable rate of 60,000 hectares a year. Kaingin was justified only during the early pre-Spanish days when people had to hack through the forest in the plains to make space with which planting of crops can be made. But with this practice persisting up to this day, its effects are destructive because lands not suited for agriculture are denuded. Whatever good it can give the kaingine­ ro is negligible compared to the suffering it causes to people living today and to the future generations. Without forests, we won't have enough wildlife with which to sustain at leas! a sig­ nificant number of our rural population; without forest watersheds multi-purpose dams would be useless as in a few years, silting will set in; without forests, there won't be the trees from which a great percen!age of our national income comes, without fores ts, the plains and cities will be inundated causing unimaginable destruction to life and p roperty. The problem is na!ional in scope. b involves not only the government but every citizen of the country. The problem cannot be ignored because everyone, whe!her he be in the city or in the farm would be adv. ersely affected if our forests are des!royed. Numerous solutions to the problem have been offered. Some people and some or­ ganizations have already implemented meas'Lres that u:ould, even in a limited way, con­ serve the remaining forests and regenerate the denuded ones. The first concerted effort towards find:ng and executing solutions to the kaingin problem was made in the National Conference on the Kaingin Problem attended by no less than high governmen! officials, logging businessmen and forestry experts. The conference had a set of goals, which even if only half of them are fulfilled, would go a long way towards finally solving this problem. What is significant wirh the conference is that for the first time men directly in­ volved with the forest have banded together to seek a common front and a common set of solutions with 1chich the problem could be tackled. At this stage, it cannot be said vet 1chether the conference had been a suc~ess or not. To be sure, the people who at­ .tended the conference never even imagined that with them meeting tof!ether, the prob­ lem could be finally solved. Kaingin is a practice that antedates even the Spanish "discovery" of the Philip­ pines. Certainly it need not take as long a time to solve it, for then we won't have any fores! to save. But this must be considered inasmuch as it had already been in­ grained in the mind of the kainginero that the forest is not a public preserve but a commodity open to everyone. Kaingin persists because those who pra~tice it are not conscious or unable to find. any other way of making a living. The kainginero, most often is invincibly ignorant of the crime he does to the country and to the future generations when he cuts or burns an apparently insignificant tree. He must be taught that the forest is not good for ag­ ricultural crops; he must be guided as to how to make use of the forest - properly; he must be helped improve his status so that he won't resort to destroying the forest to keep his stomach full.
