These animals are part of the park service string of 37 horses and 25 mules used for lookout station and trail camp provisioning and inspection trips.

No longer considered fit for packing on park trails are Hornet, 22 years old; Sox and Dan, both 21, and Spike, the mule, 14. Also to be offered for sale is Sam, 23, a big bay. He's been in the park since 1935, and has been Ranger Joe Heimes saddle horse in the Belly river district. Ranger Heimes often rode him without a bridle using just a hacka-more. Sam on occasion would ridden by lookouts to their mountain top posts.

On arrival on the mountain top, Sam would be turned loose and he returned to the ranger station on his own. Hornet once was a rodeo bucking horse. He turned into a steady pack horse that for 16 years has been transporting loads to isolated parts of Glacier. Retiring old horses and mules causes considerable concern among park rangers and packers. They become attached to the animals.

Thought of a sale to fox farms or an abusive owner is disturbing. the other hand the park budget does not provide funds for horses no longer fit and able to work.

More than 100 freight carloads of spruce pulp from tht Flathead river's south fork will bt shipped to Green Bay, by Gla-cier-Coram Lumber company, Martin City, and Forest Products company, Kalispell.

First four of the cars have been loaded here. The Montana firms have a contract to supply 3,000 cords of pulp-wood this fall. The spruce trees from 4-inch tops up are coming from a Flathead national forest purchase in the upper Emery creek drainage. The operation is employing 20 local men. planes and one privately owned oi ine airplane.

Alter two plane are as yet equipped with ranges simultaneously until aircraft users have had ample time to get omnirange receiving equipment and become familiar with the new system. The usably range of VOR in Missoula varies from 27 to 48 miles on the regular airways. The VOR here interlocks with the next one to the east, at Drummond, and to the west, at Mullan pass. The transmitting equipment in VOR building consists of steel cabinets covered on the front with indicator lights, dials and switches and packed inside with tubes, motors, wires and other electrical gear ir almost unbelievable quantity. The monitor unit alone contains 28 tubes, most of them dual purpose, to keep a constant check on the operation of the station.

Atop the building are the aerials, protected by a plastic dome. The aerials don't look like the wire you string between the house and garage for your home radio. They are flat metal plates bent into precise shapes and there are five of them. An automobile driven up to the isolated building must be parked under the "shadow" of the circular roof so the metal mass won't upset the delicate electrical balance. The man with the 28-tube brain he must have one to understand When he passes over the range station, the pointer will switch from the word "To" to the word "From." This gives him an exact "fix," pinpointing his position.

If the pilot wants to continue the same course, he can continue flying with the needle centered. Or if he wishes to change course, he can tune in a new course on the azimuth selector in the direction toward which he wishes to fly. A pilot can fly on an omnirange either in front or behind him. The "To" and "From" indicator prevents confusion, and the bearing of the station always shows clearly below the indicator. At any time the pilot needs an exact "fix," he can tune in a station to one side of his course, determine the bearing of the station, and plot it on a chart.

The intersection of two such lines, taken from two different ranges, shows his exact position. Eventually, each omnirange will be equipped with a distance measuring equipment transmitter. This will show the pilot on a dial his exact distance from the omnirange to which he Is tuned, and make it unnecessary for him to take cross-bearings to determine his exact position. The CAA will continue to operate omniranges and low frequency It not only shows the pilot that he is off course, but tells him approximately how many degrees he is off. Here's how the pilot uses omnidirectional receiving equipment: it who takes care of this electronic i cise location will be known.
