But Steele now had an excuse tor refusing to take Kose La flamme to the railroad. "You understand, David? Keep your knife out of him. Your turn will «orne on the snow. Now get the canoe!" David carried Laflamme into the •back,' and went for the canoe. Returning to the girt, trembling In the dark, Steele said ; "It was he. David knocked him out, but he's not hurt. Ws mart get away at once." With an Impulsive movement. Rose Laflamme found Steele's neck with tier arms and kissed him wildly. "But," explained the harassed American, "we've got to travel fast; they'll follow os—we can't take you!" "You mean you'll not take me now?" gasped the girl in her despair. "We'll have to run the portages, break our backs to beat the Indians he'll send after us. If you go, they'll get us!" protested Steele. "Take me. take me with you!" she moaned. "Am I not beautiful, beeg American? Don't leave me here!" Then Brent Steele gambled: "What was Pierre doing down river?" "I weel tell you In the canoe." she parried, and he crunched his teeth In bis chagrin. "Wheu we are In the canoe 1 will tell you thlnga—things you nevalre dream of," ahe urged, "I know all." She would exchange her Informa tion at a price—her freedom ; and that price Steele would not pay. But It was necessary to get her back to the bouse. * "All rlgut," he said, "go and get «0 me heavy clothes, and be at the log landing In an hour. Don't make any noise. We don't want them to find Laflamme until morning. Now be careful !" With a low cry, she again circled Steele's neck with her arms, kissed him and disappeared. In an hour he and David would be far down the lake on their way to Neplgoq house. She had Intended making a catspnw of him to escape from Ogoke and Steele wasted no èympathy on her. He wondered whether, on finding herself tricked, she would arouse the post or take to her bed. feigning ignorance of the whole business. And he also wondered whether If Denise St. Onge ever learned of this night's work at Ogoke, she would he llere that every act and word of his had teen In her service. Through the night, the churn-swish, chnrn-swlsh of the paddles of David and Steele ceaselessly marked off the miles, for with the sun might come a head wind, which meant fighting for every foot while their pursuers gained on them with a four or six-man crew. Time and again through the long hours, the keen eyes of David alone bad sensed through the murk in which they traveled, the menace of a rocky point or the threat of bowlders, awash, square In their course. "How far have we come?" asked Steele, laying his paddle on the gun wale to stretch his stiffened arms. "Wal, dees point ees vert far up de lak'. Keen two hour we hit de Inlet." "Good l If that Is so, we're thirty miles ahead of them." • The OJibway shook his head. "We tak' no chance—we travel lak' h— 1 !" On shore the tea-pall was soon bolt ing, while David and Steele over hauled their scant supplies. There were barely beans, bacon and flour to do a week, and Neplgon lake was two weeks' hard travel. It meant shoot ing their way out, unless the fish would bite, for they bad given their net to MicheL . "Let's have a look at the old Mann licher," said Steele as David watched the bacon sputtering In the pan. "We may need her before we get out of this mess. I was a fool to stop there. I might have—" He had thrown the holt-handie up and back, when his face sobered. The startled eyes which met the Inquiring gaze of the man at the fire drew a quick: "W'at you see —ghost?" Making no reply, Steels sprang ts the canoe, tore the lashings from a bag and fumbled with Its contents— «ben emptied the bag on the beach. Taking David's rifle from the canoe, he opened th# breach. "Both guns empty!" he said in dis may. 'They've got our sheila—two boxes in the bag! Not a shot left cleaned ouf Î" The white man looked long Into the Immobile face of the Indian. "If they catch they don't, we can't even shoot our way home. IPs fish—or starve!" The OJibway squatted on hts heels and resumed bis frying.

By CARLTON E. BUTLER, Member American Inatltuta of Electri cal Engineer« and Inatltuta of Radio Engineers. Changing conditions make new radio circuits necessary. A few years ago the single circuit and ultra audlon receivers were satisfactory and were capable of bringing In dis tant stations with volume. Today the same sets cannot be used, except In Isolated districts away from broad casting stations, due to their broad tuning qualities. The receiver of the earlier day Is no longer satisfactory for other rea sons, principally on account of Its squealing and radiating qualities and because Its tone quality I» poor and distorted. At the last radio confer ence In Washington It was agreed that In the near future the use of radiating receivers would have to be ended, even If It became necessary to pass a fed eral law to accomplish that result Today, with modern laboratory standard apparatus available, and with sets of better design, the quality attains the standard demanded by lovers of music, The R-4 circuit, as developed for use In a new receiving set, is a good example of present day design. The most popular form of circuit was selected—the five tube tuned radio frequency—and by the use of the lat type of condensers, colla, and transformers, together with Improve menta In the circuit, produced a re cel ver that Is capable of tuning through Interference, bringing In sta tlons from a distance on the loud speaker, and surpassing many re celvers for all around performance and quality of tone, To 8hut ©ut Stray Currants. Noteworthy of the Improvements In t j, e circuit are two by-paas fixed con dengt . rs . between the primary of each n f the first two radio frequency trans former* and the filament. This serve* by-pass and keep stray radio fre qneiicy currents out of the rest of the wiring, and stabilises the circuit A large condenser 1* placed across the "B" battery terminals to reduce noise* and howls due to long leads or low voltage. Refinements In apparatus Include the new square wound toroid coll, wlttt the new straight line frequency condensers which provide shielding of electromagnetic lines of force, as well an keep the Instrument duatproof, a mighty Important detail. The toroidal colls eliminate the spraying effect of magnetic lines of force within the set proper, and re move the principal troghear that radio engineers have been working for years •<>•**• The colls have self-con '«toed fields that make pickup of stray **rr«at Impossible.

The rheostats should each be of six ohms capacity for the use of UV 201-A or C 301-A tubes, and the grid leak R3 should he two megohms. When using the new UX amplifier tubes, break the grid return of the last transformer and Insert "C" battery of voltage recommended by the manu facturer. The first rheostat Is used as a Volume control, to moderate -dgnal strength to the desired extent. For most satisfactory operation, the cor sect setting of this control may be determined by trial, and then allowed to remain without further adjust nient complete th# set The terminal* of the radio fre Tn addition to The apparatus named shove, you wilt need five socket*, a 7 by 24-lncb panel, baseboard or sub panel, wire, screws, solder, etc., to quency transformers are unmarked In the diagram. The first coll Is a coupler, with two taps taken off for long and short aerials. Both taps are marked "A" and each should be tried and the aerial connected to the one that gives the beat résulta. The other two taps are the secondary connec tions and marked In the regular way. The outside terminals of the second and third colls are the primary posta, the Inside terminals being the "G" and "F" secondary terminals. -r Three-Circuit 1« Best Short-Wave Radio Set An easy short-wave set to build Is one on the order of the three-circuit set. The tuner for this set Is made from any good three-circuit tuner about 4 Inches In diameter. The secondary consists of ten turns of No. 12 D.C.O. wire, the primary of four turns of tho same else wire, the two being medium coupled. The tickler has 20 turns of No. 20 D.C.C. wire. The secondary Is tuned with a .0006 mfd. condenser as shown by the V V ? 'p i 9 ^sw 4 i m\ ME VIE ♦ • • • JL Diagram Showing Circuit of the Short Wave Set • sketch. Another Important point to note Is In winding the tickler. To oh tain the best results care should he taken to see that all turns are wound In the same direction and an even number of turns on each side of th« shaft. This aet will receive approximately from 2,000 to 10,000 kilocycles, or fron 40 to 190 meters. However, every aet is different and In order to check yom maximum and minimum wave-lengthi you should obtain Information from the standard frequency station as tc when they send test programs, snd with these signals you will be able to tell exactly what wave-length your sei will cover. In assembling a short-wave recelvei keep In mind the fact that all lead! should be Just as short as you cas make them.

Straight Line Tuning Making Bid for Favoi The coming of the straight line fre quency condenser and the later ar rival of the S. L. F. dial converter hat brought the subject of straight line tuning very much to the fore. Tto< choice* between the two Instrument« rests with the radio fan when be de cldes to simplify the toning of bit receiving set. condensei of the concentric plate type will solve the problem of obtaining simpllcltj In tuning by an electrical method and it Is conceded that the best waj of solving an electrical difficulty 1« by an e lectric al cha nge. The 8. L. F dial will afford one dial visibility and greatly simplify ths tuning of short wave stations, and wliereln a change of condensers would entail too much work, may be used. It must be remembered, however, that the 8. L. F. converter di«U la a me chantes! device and therefore will not entirely solve an electrical problem. To Avoid Body Capacity A good general rule where the ob ject is to avoid body capacity la to always make that terminal of the to st rainent to which yonr hand comes the closest when toning, at or near ground potential. As most circuits are tuned by s variable condenser across a cod, the rotor plates should be the end connected to the filament circuit. The hand, In effect, comes closest to these plates since the rotor plates connect to the shaft and the shaft carries the dial.
