hes e are located thirty feet or more below the surface of the ground before the water reaches these reservoirs it must pass through deep bodies of band which act as a filter Aft after erthe the water works were finished there was complaint of an exceedingly offensive odor from the water upon Inesti investigation gation it was discovered that this odor was caused by a very extensive growth of algae it seemed to flourish quite as a luxuriantly as though it were locate 1 upon thi thit surface of the earth after many trials it was found that co covering ering the water would prevent the growth but in the course of the trials a curious fact fame came out that if boards were laid eist e and west they would scarcely interfere with the development eloP ment of ills form of vegetation this was accounted for by the fact that the light from east to west over oler the surface of the water when nhen the boards were viere placed north and south the alternate alter light and shadow appeared to check its development it was furthermore learned that when the boards were tour four feet above the water with one and ahalt halt inch wide spaces between the algae would not grow but it put close to the surface say a foot or so their presence did not seem to interfere with the production of the plant it la is tn in to note that the pi ence of a certain form of vegetable growth Is indispensable to the proper keeping of water it ai at pears that without these various forms of injurious bacilli four ish in great numbers the growth Is a devouring element and takes up from the water many of those things which would be deleterious if kalmn into the human system the foot root of the lite Eiery everything thing in any way ay connected with alaska and the klondike la is of special interest at present and among items the foot of the rein reindeer deserves particular mention the forefoot of the horse to a great extent determines its value as upon this portion of its anatomy its speed and en
