 the smokestack of the new Ice Plan
 of Halbert 6t Pools the SENTINE scribe went down to investigate ant
 was we'll repaid by seeing one of tn
 most complete plants in the who'll
 country, thorough the courtesy o
 Mr. Pool.
 The 'aain Suilding is 40xS0 feet
 divided Into several different com
 partments. Engine and pump de
 partment, freezing department, three
 cold storage rooms and entrance
 rooms to cold storage rooms So ar
 ranged that the hot air from the out
 side cannot get into the cold storage
 rooms while they are opened. Tht
 whole plant is up to date and as conn
 plete as money can buy.
 The power consists of 60 horse
 power Corlis Engine fed by ar
 eighty horse power Loiler. Tn:
 engine and ammonia pump arc of the very latest and most improved design, and illustrate the immense advance made in the me- chanical sciences in the past few years. The process after one has il explained to him seems very simple although reached by complicated process. The ice is frozen in galva- nized iron cans that hold 900 lbs each after freezing. These cans are en- closed within coils of inch pipe through which ammonia gas is forced at high pressure. The pipes and cans are placed in large tank which holds enough cans to make twenty tons Of ice, and this tank Is filled with salt brine and entirely surrounds the cans and coils of pipe. The cans themselves are filled with water that is condensed and filtered by very elaborate process. The water is first, after being pumped out of the we'll, boiled, then condensed and run into a tank in the bottom of which is some coiled pipe through which steam is passed having the effect of forcing all the air out of the water. The water is then foraed through two filters of sand and charcoal and into another tank, which is immediately over the cans to be filled in the tanks; through this is forced ammonia gas. thus making the water ice cold. It is then forced through a sponge filter and into the cans through an automatic filter which prevents any air fLom getting into the water, thus insuring solidity to the ice. The va ter IS then ready to be frozen into ice that is pure as it is possible to be made and as clear as a piece of glass. Running above the tank in which the ice is frozen is a travelling crane with which they lift the cans out of the brine and carry them to the end where they are low cred into an automatic dumping cart. This cart looks almost like an or dinary dump car st mine. The can is lowered into a square iron box just trif1e larger than the can and the same shape, as soon as 1t is lowered the iron box turns down ready to dump the ice; as it turns down it opens a small valve which causes spray of hot water to strike all sides of the can containing the ice thus melting the outside sufficient for the cake of ice to slip out of the open end of the can, which it does into their cold storage room which has capacity of 120 tons.
 Besides this storage room which is intended to hold their reserve supply of ice; they have two other rooms l8x20 it. which are fer their custom CTS. These room are constructed in such a manner that it will not be necessary for them 10 run the plant all the time in order to keep them cool. The walls are all double and packed with mineral wool, and the floors have four inches of cement on them. They are so built that there is constant circulation of cold air all around the rooms. For keeping them cold while running they have pipes through the rooms through which the ammonia gas'is pumped, and while not running they can store ice in the up per story, as 1t were, which will ans- wer the same pursose.
 This morning the plant started and by tomorrow will be dispencing ice to their patrons at price never be- fore heard in Yuma. Taken all in all the plant is a great credit to Yuma and shows the faith which Messrst Hslbert & Pool have in Yuma. Nothing which money could do has been spared to make this, what It is, the most complete ice plant in Ari- zona. The SENTINEL congratulates them on the completion of their en-
