CENTURY MARK
 NOT HERE YET
Weather Man Says This is Cool Year mi Record is Broken " Era of Office Progress Sets in ill the Phoenix Bureau

Now it will be better understood what is meant by the phrase It's cool here"
 Phoenix broke d weather record ,esterday-sm it right in two. It advanced the date upon which il first registers 100 degrees at least tWenty-four hours The latest sfirst hundred" was recorded for June Is 1901 and this year June Is has pass ed without the thermometer in the big chicken cocp atop the Federal Building having touched the century mark The earliest hundred recorded in the seventeen years since weather records were first taken in Phoenix was April lo 1910.
 Speaking of temperatures. it is here apropos to remark that Phoenix is not measured with the same weather stick that is in use in the east. where humidity is strong factor In a conversation with Sec ten Director Briggs yesterday it was developed that it is necessary to Introduce 9 different standard of re- cording summer daytime tempera- lures in Phoenix than is used in the humid east. Because in most sec tions of the country the heat is con sidcred excessive when it reaches 90 degrees. actually causing extreme bodily discomfort which increase with each additional degree above that point until 100 degrees is reached and it becomes almost unbearable, all weather bureau stations in the Unit ed States are required to keep q re- cord of the number of days in each month upon which the maximum temperature reaches 90 degrees. or above. Such record has been kept in Phoenix for the last seventeen yeasr but for the hot months it means nothing here It is seldom during July and August that the tenn perature does not reach the ninety degree mark In fact these months in more than half of the seventeen years of record have contained 90 degree days all through. For the entire record at Phoenix, loo degrees has been used as the basis for an additional record for local use. To the customer the discussion of three figure temperatures in any matter of-fact manner as the common oc- currence would seem horrifying in the extreme, while as a rule a day in AIizona when the temperature is be- tween 90 and 100 is very comfortable indeed This seems incredible to resident of an eastern state.
 But Phoenix can go further than this It has been discovered that letter results will be gained from keeping a record of days upon which the mercury climbs to or above the 1O5 degree mark, and so new com pilation will be made on this basis. l. is considered that d chart built on a 105 degree record would very closely correspond with the standard of 90 degrees in use in the more humid states.
 There is much discussion, especial ly among old residents, about the gradual cooling of this part of the state. on the whole the later Years have been cooler than those near the top of the column compiled since 1896. But 1910 has been the hottest year ever recorded by the local sta ton. Taking a mean for the year, it is discovered that 1910 was 71.5 de- grees while 1912, the coolest year on record was but 68.2. It may be re- marked here that tenth of a de- gree in mean annual temperatures counts for a lot more than it seems. The highest temperatures for year closely follow the average found by taking the means of the months of June July August and September. This is not true of coolest tempera- tures, for often a year that has the most cool days may have d few very hot ones that bring the mean up to a remarkable figure. 1912 had the cool est four summer months, the average being S41. There were two years that had highest summer months av- erages. 1910, the champion hot year. and 1898. which was not nearly so hot, the means being SIS degrees.
 This year. judging by it's start, may be cool one, even cooler than last, which was the record, but there is no certain way of predicting, for few days of real hot weather may raise the mean annual mark.
 The Phoenix office of the weather bureau is now all in it's new quar- ters in the Federal building Settling down time past. the office is now engaged in bringing everything up to date, both in records and the ma chimes with which they are kept A new machine was added yesterday being the card index addressograph This instrument is set of cards for regular form drawer index. but diff fering from ordinary indexes in this particular The cards have the ad- dress in raised tin letters, so drawerful of them can be fed through the machine and the addresses print ed on separate slips. This operation can be performed with great rapidity and there is the advantage of having the card index easily accessible just the same. The lists can be changed inspected, increased or decreased at the will of the operator without trou- h NY iC inn 1rC1sr 1fyof over the other system which used rubber typed addresses on long chains of holders
 The addition of the new addressing apparatus is in line with the policy of keeping in touch with the most advanced business machinery, and marks step in progress for the
