if anything serious could have happened to him。 Mercedes showed a slow； wearing strain。
Thorne's commission expired the end of January； and if he could not get his discharge immediately； he surely could obtain leave of absence。 Therefore； Gale waited； not without growing anxiety； and did his best to cheer Mercedes。 The first of February came bringing news of rebel activities and bandit operations in and around Casita； but not a word from the cavalryman。
Mercedes became silent； mournful。 Her eyes were great black windows of tragedy。 Nell devoted herself entirely to the unfortunate girl； Dick exerted himself to persuade her that all would yet come well； in fact； the whole household could not have been kinder to a sister or a daughter。 But their united efforts were unavailing。 Mercedes seemed to accept with fatalistic hopelessness a last and crowning misfortune。
A dozen times Gale declared he would ride in to Casita and find out why they did not hear from Thorne； however； older and wiser heads prevailed over his impetuosity。 Belding was not sanguine over the safety of the Casita trail。 Refugees from there arrived every day in Forlorn River； and if tales they told were true； real war would have been preferable to what was going on along the border。 Belding and the rangers and the Yaqui held a consultation。 Not only had the Indian become a faithful servant to Gale； but he was also of value to Belding。 Yaqui had all the craft of his class； and superior intelligence。 His knowledge of Mexicans was second only to his hate of them。 And Yaqui； who had been scouting on all the trails； gave information that made Belding decide to wait some days before sending any one to Casita。 He required promises from his rangers； particularly Gale； not to leave without his consent。
It was upon Gale's coming from this conference that he encountered Nell。 Since the interrupted siesta episode she had been more than ordinarily elusive； and about all he had received from her was a tantalizing smile from a distance。 He got the impression now； however； that she had awaited him。 When he drew close to her he was certain of it； and he experienced more than surprise。
〃Dick；〃 she began； hurriedly。 〃Dad's not going to send any one to see about Thorne？〃
〃No； not yet。 He thinks it best not to。 We all think so。 I'm sorry。 Poor Mercedes！〃
〃I knew it。 I tried to coax him to send Laddy or even Yaqui。 He wouldn't listen to me。 Dick； Mercedes is dying by inches。 Can't you see what ails her？ It's more than love or fear。 It's uncertaintysuspense。 Oh； can't we find out for her？〃
〃Nell； I feel as badly as you about her。 I wanted to ride in to Casita。 Belding shut me up quick； the last time。〃
Nell came close to Gale； clasped his arm。 There was no color in her face。 Her eyes held a dark； eager excitement。
〃Dick； will you slip off without Dad's consent？ Risk it！ Go to Casita and find out what's happened to Thorneat least if he ever started for Forlorn River？〃
〃No； Nell； I won't do that。〃
She drew away from him with passionate suddenness。
〃Are you afraid？〃
This certainly was not the Nell Burton that Gale knew。
〃No； I'm not afraid；〃 Gale replied； a little nettled。
〃Will you gofor my sake？〃 Like lightning her mood changed and she was close to him again； hands on his； her face white； her whole presence sweetly alluring。
〃Nell； I won't disobey Belding；〃 protested Gale。 〃I won't break my word。〃
〃Dick； it'll not be so bad as that。 Butwhat if it is？。。。Go； Dick； if not for poor Mercedes's sake； then for mineto please me。 I'llI'll。。。you won't lose anything by going。 I think I know how Mercedes feels。 Just a word from Thorne or about him would save her。 Take Blanco Sol and go； Dick。 What rebel outfit could ever ride you down on that horse？ Why； Dick； if I was up on Sol I wouldn't be afraid of the whole rebel army。〃
〃My dear girl； it's not a question of being afraid。 It's my wordmy duty to Belding。〃
〃You said you loved me。 If you love me you will go。。。You don't love me！〃
Gale could only stare at this transformed girl。
〃Dick； listen！。。。If you goif you fetch some word of Thorne to comfort Mercedes； youwell； you will have your reward。〃
〃Nell！〃
Her dangerous sweetness was as amazing as this newly revealed character。
〃Dick； will you go？〃
〃No…no！〃 cried Gale； in violence； struggling with himself。 〃Nell Burton； I'll tell you this。 To have the reward I want would mean pretty hear heaven for me。 But not even for that will I break my word to your father。〃
She seemed the incarnation of girlish scorn and wilful passion。
〃Gracias； senor；〃 she replied； mockingly。 〃Adios。〃 Then she flashed out of his sight。
Gale went to his room at once； disturbed and thrilling； and did not soon recover from that encounter。
The following morning at the breakfast table Nell was not present。 Mrs。 Belding evidently considered the fact somewhat unusual； for she called out into the patio and then into the yard。 Then she went to Mercedes's room。 But Nell was not there； either。
〃She's in one of her tantrums lately；〃 said Belding。 〃Wouldn't speak to me this morning。 Let her alone； mother。 She's spoiled enough； without running after her。 She's always hungry。 She'll be on hand presently； don't mistake me。〃
Notwithstanding Belding's conviction； which Gale shared； Nell did not appear at all during the hour。 When Belding and the rangers went outside； Yaqui was eating his meal on the bench where he always sat。
〃YaquiLluvia d' oro； si？〃 asked Belding； waving his hand toward the corrals。 The Indian's beautiful name for Nell meant 〃shower of gold；〃 and Belding used it in asking Yaqui if he had seen her。 He received a negative reply。
Perhaps half an hour afterward； as Gale was leaving his room； he saw the Yaqui running up the path from the fields。 It was markedly out of the ordinary to see the Indian run。 Gale wondered what was the matter。 Yaqui ran straight to Belding； who was at work at his bench under the wagon shed。 In less than a moment Belding was bellowing for his rangers。 Gale got to him first； but Ladd and Lash were not far behind。
〃Blanco Sol gone！〃 yelled Belding； in a rage。
〃Gone？ In broad daylight； with the Indian a…watch…in？〃 queried Ladd。
〃It happened while Yaqui was at breakfast。 That's sure。 He'd just watered Sol。〃
〃Raiders！〃 exclaimed Jim Lash。
〃Lord only knows。 Yaqui says it wasn't raiders。〃
〃Mebbe Sol's just walked off somewheres。〃
〃He was haltered in the corral。〃
〃Send Yaqui to find the hoss's trail； an' let's figger；〃 said Ladd。 〃Shore this 's no raider job。〃
In the swift search that ensued Gale did not have anything to say； but his mind was forming a conclusion。 When he found his old saddle and bridle missing from the peg in the barn his conclusion became a positive conviction； and it made him； for the moment； cold and sick and speechless。
〃Hey； Dick； don't take it so much to heart；〃 said Belding。 〃We'll likely find Sol； and if we don't； there's other good horses。〃
〃I'm not thinking of Sol；〃 replied Gale。
Ladd cast a sharp glance at Gale； snapped his fingers； and said：
〃Damn me if I ain't guessed it； too！〃
〃What's wrong with you locoed gents？〃 bluntly demanded Belding。
〃Nell has slipped away on Sol；〃 answered Dick。
There was a blank pause； which presently Belding broke。
〃Well； that's all right； if Nell's on him。 I was afraid we'd lost the horse。〃
〃Belding； you're trackin' bad；〃 said Ladd； wagging his head。
〃Nell has started for Casita；〃 burst out Gale。 〃She has gone to fetch Mercedes some word about Thorne。 Oh； Belding； you needn't shake your head。 I know she's gone。 She tried to persuade me to go； and was furious when I wouldn't。〃
〃I don't believe it；〃 replied Belding； hoarsely。 〃Nell may have her temper。 She's a little devil at times； but she always had good sense。〃
〃Tom； you can gamble she's gone；〃 said Ladd。
〃Aw； hell； no！ Jim； what do you think？〃 implored Belding。
〃I reckon Sol's white head is pointed level an' straight down the Casita trail。 An' Nell can ride。 We're losing' time。〃
That roused Belding to action。
〃I say you're all wrong；〃 he yelled； starting for the corrals。 〃She's only taking a little ride； same as she's done often。 But rustle now。 Find out。 Dick； you ride cross the valley。 Jim； you hunt up and down the river。 I'll head up San Felipe way。 And you； Laddy； take Diablo and hit the Casita trail。 If she really has gone after Thorne you can catch her in an hour or so。〃
〃Shore I'll go；〃 replied Ladd。 〃but； Beldin'； if you're not plumb crazy you're close to it。 That big white devil can't catch Sol。 Not in an hour or a day or a week！ What's more； at the end of any runnin' time； with an even start； Sol will be farther in the lead。 An' now Sol's got an hour's start。〃
〃Laddy； you mean to say Sol is a faster horse than Diablo？〃 thundered Belding； his face purple。
〃Shore。 I mean to tell you just that there；〃 replied the ranger。
〃I'llI'll bet a〃
〃We're wastin' time；〃 curtly interrupted Ladd。 〃You can gamble on this if you want to。 I'll ride your Blanco Devil as he never was rid before； 'cept once when a damn sight better hossman than I am couldn't make him outrun Sol。〃
Without more words the men saddled and were off； not waiting for the Yaqui to come in with possible information as to what trail Blanco Sol had taken。 It certainly did not show in the clear sand of the level valley where Gale rode to and fro。 When Gale returned to the house he found Belding and Lash awaiting him。 They did not mention their own search； but stated that Yaqui had found Blanco Sol's tracks in the Casita trail。 After some consultation Belding decided to send Lash along after Ladd。
The interminable time that followed contained for Gale about as much suspense as he could well bear。 What astonished him and helped him greatly to fight off actual distress was the endurance of Nell's mother。
Early on the morning of the second day； Gale； who had acquired an unbreakable habit of watching； saw three white horses and a bay come wearily stepping down the road。 He heard Blanco Sol's familiar whistle； and he leaped up wild with joy。 The horse was riderless。 Gale's su
