Show FORESTRY A JUST at this season of the yea year r the sub subject N act of planting out trees with a view to raising a supply of dd or timber far other othor purposes very properly occupy the attention of our agriculturists but littlehat ehas been done in this line in utah yet and the tile depletion of the tile limited supply of timber which our surrounding mount mountains airis afford has been going on year after af to er year without thought or care as as to where our future f supply is to come from there Is is considerable rable rabie waste land in various parts of our territory in the valleys as well weil as in the mountains that might rn g ht very profitably be planted with wit it trees tr e S there are other reasons than those whichard chare likely to suggest themselves to the ordinary utilitarian i why a general system of timber culters should be adopted the arid atmosphere orthis of this inland mountainous region might be materially modified thereby weare we h i f A 11 J not among those who imagine that the climatic changes which hive have occurred in our territory since the date of its ltd settlement are due due to the cultivation of the soil and the increase of ve vegetation elation in view of the comparatively small area of cultivated land laud which there Is in our territory andt and thu the iles lits wonderful difference feren a between b e tween the rainfall now and t thirty arty I 1 se seven v en years ago the idea of thus accounting for tor the change Is preposterous we prefer to believe in a special providence in favor of the saints at the same pame time we are f fully ally of the opinion that a great influence Is exerted over the atmosphere by vegetation and especially by forests mr F K carey has lately been contributing a series of articles to the chicago current on the uses of forests which contain some good ideas that he has collated from various sources upon the subject some of which we will quote trees are heated and cooled by radiation but very slowly and hence the daily maxi maximum murd muir and minimum of temperature they register occurs some hours after the same phases of temperature in ili the atmosphere but tree radiation is not confined to a thin stratum of air it is widely diffused and hence the conser conserving vim influences of f orests forests upon climate maing making the nig nights hit lit warmer and the days cooler so too evaporation from iree tree soils Is is slow the trees ta take ce u the moisture of dam damp soil and hence ence it is that forests absolutely ariso diminish dl the evaporation 1 and increase the tile humidity of ef climates climate within their in influence bence when rain falls upon unprotected acted soil it more speedily runs off to the drainage streams str eams cams but if tree pro the process Is slow and a part of the moisture is taken up by the roots and leaves and thui thu percolates through the soil and Is dispersed into the atmosphere again it Is settled then that trees increase the humidity of the atmosphere and the least cultured will cheref therefore ore see how it is that tree growth glowth so immediately affects climate and how it Is that large areas devoid of forests are subject to the extremes of great heat and cold great precipitation of rain and excessive droughts most rivers and springs rise in forests and as these latter preserve moisture in the soil they are important factors in the integrity of streams and springs in a region theretofore rainless egypt by grove rove planting near the mouth 0 of the suez canal has occasioned plentiful f

spring sprint was dried up by land clearings but badt restored by fo resting forests lessen the liability of freshets fresh tresh ets upon rivers most of which have th their air sources in forested mountains and pass through woodlands in some of their reaches the forests retaining moisture in ln the soil feed the rivers gradually and prevent sudden demands upon them for water carriage they retain the snows also and prevent sudden thaws and thus avert disaster ut to rivers trees make a soil f friable and better able to retain moisture and better able to distribute it without the forest the soil Is liable to harden and resist penetration by b rain and hence deforested forested de river sections experience rapid and dangerous rises inthe streams in switzerland the government has very
