Before SCHWAB, C.J., and FOLEY and FORT, JJ.
SCHWAB, Chief Judge.
This is a juvenile case. A petition was filed in juvenile court on May 16, 1969, charging Paul Zorner, then 14 years of age, with willfully setting fire to the home in which he lived. Counsel was appointed on June 9, and a hearing before the juvenile *991 court was set for June 23. On June 17, the juvenile's counsel moved for a continuance beyond June 23. The motion was denied, as was a motion for a jury trial, and the hearing took place on June 23, and June 30, before the juvenile judge. On October 15, 1969, the court entered its "Order and Disposition," stating in pertinent part:
"3. The above-named child [Paul Steffen Zorner] is within the jurisdiction of the Court by reason of the following facts:
"From the evidence presented at the hearing held on the 23rd day of June, 1969, said child was found to have set fire to a dwelling,
"* * *
"NOW THEREFORE IT IS HEREBY ORDERED AND ADJUDGED:
"* * *
"2. THAT the above-entitled matter be continued for a period of six months at which time this will come on for review, and
"3. IT IS FURTHER ORDERED that Paul Steffen Zorner and his mother, Harriet Grace Zorner obtain independent counseling through the efforts of their attorney * * *."
From this order the juvenile appeals,[1] assigning as error (1) the court's denial of the motion for a continuance, (2) the court's denial of defendant's demand for a jury trial, (3) the court's exercise of jurisdiction over the defendant under a statute requiring only "a preponderance of the evidence," and (4) insufficiency of the evidence to support the finding that the defendant committed arson.
The juvenile's attorney filed a motion for continuance eight days after he was appointed and six days before the scheduled hearing. The accompanying affidavit stated as grounds for the continuance that: (1) a number of witnesses had to be interviewed; (2) he has to acquaint himself with the fire and the procedures of fire investigation; and (3) the defendant was attending a music workshop in another city and would not return until about a day before the hearing. No formal ruling was made by the court, but at the hearing, and in answer to the court's question of whether the defendant was ready to proceed, the defendant's attorney answered in the affirmative. After the state had rested, the court did grant the defendant a one-week continuance to present his case. The granting of a continuance is within the sound discretion of the trial court, and will not be disturbed unless there is an abuse of discretion and prejudice to the defendant. State v. Young, Or. App., 90 Adv.Sh. 17, 463 P.2d 374 (1969), and State v. Sands, Or. App., 90 Adv.Sh. 1397, 469 P.2d 795 (1970).
The juvenile and his attorney had conferred prior to the June 17 request. Counsel had available to him a complete file concerning the occurrence. State v. Young, supra, states that in seeking a continuance a defendant should demonstrate the problems confronting him were different from those expected in any criminal case. He did not do so here.
In State v. Turner, 253 Or. 235, 453 P.2d 910 (1969), the defendant, on the basis of Bloom v. Illinois, 391 U.S. 194, 88 S.Ct. 1477, 20 L.Ed.2d 522 (1968); Duncan v. Louisiana, 391 U.S. 145, 88 S.Ct. 1444, 20 L.Ed.2d 491 (1968), and In re Gault, 387 U.S. 1, 87 S.Ct. 1428, 18 L.Ed.2d *992 527 (1967), challenged the constitutionality of ORS 419.498(1), which denies a juvenile the right to trial by jury in a delinquency hearing. The Oregon Supreme Court, in deciding against the defendant's position, stated:
"* * * A majority of this court has concluded that the statute should be considered constitutional until the United States Supreme Court holds otherwise." State v. Turner, supra, 253 Or. at 237, 453 P.2d at 911.
ORS 419.500(1) allows a finding of jurisdiction over a juvenile by a preponderance of the evidence. State v. Arenas, 253 Or. 215, 453 P.2d 915 (1969), upheld the constitutionality of this statute. In the Matter of Winship, 397 U.S. 358, 90 S.Ct. 1068, 25 L.Ed.2d 368 (1970), held that a finding of guilt in a juvenile case must be beyond a reasonable doubt. Here, the trial judge recognized and applied the Winship standard. In an order entered on September 10, after the hearing was concluded, but prior to the order appealed from, he said that he found from the evidence:
"* * * [B]eyond a reasonable doubt, that the child * * * did wilfully set fire to the residence * * *."
The remaining question is whether the evidence demonstrates that "beyond a reasonable doubt" the defendant set fire to his dwelling. Assuming that ORS 419.561(4)[2] requires us to try this matter de novo on the record, we conclude that the trial judge's finding was correct. This issue turns largely on the credibility of witnesses, particularly the credibility of the defendant, and for this reason we give great weight to the trial judge's finding. Hannan v. Good Samaritan Hospital, Or. App., 90 Adv.Sh. 1517, 471 P.2d 831 (1970).
"Both the criminal agency in the origin of the fire and the identification of the accused as the one who committed the crime charged may be established by circumstantial evidence * * *." State v. Director, 113 Or. 74, 84, 227 P. 298, 300-301, 231 P. 191 (1924).
The evidence is that the fire was of incendiary origin, and that it started inside the Zorner residence. The juvenile admits he was in the residence when the fire started. It is clear from the record as a whole that he was the only person inside the residence at the time. His hair was singed. At the trial he suggested that the fire could have been started by someone throwing something through the living room window. In an attempt to argue that hypothesis to the court, the defendant refers in his brief to the traffic on the road adjacent to the Zorner residence and to the presence of a state's witness in the Zorner front yard a few minutes before the fire started. However, this conjecture is clearly refuted by the expert testimony that the fire had two distinct points of origin; one in the living room and one in the dining room.
Affirmed.
NOTES
[1]  On May 1, 1970, the court entered an order terminating jurisdiction. ORS 419.561(1) states:

"Any person whose rights or duties are adversely affected by a final order of the juvenile court may appeal therefrom * * *." (Emphasis supplied.)
There may be some question as to whether the order appealed from, the order of October 15, was, in fact, a final and, thus, an appealable order. See Logsdon v. State and Dell, 234 Or. 66, 380 P.2d 111 (1963). But see State v. Gates, 230 Or. 84, 368 P.2d 605 (1962). Here the state does not challenge the finality of the order appealed from, and we do not consider that question.
[2]  ORS 419.561(4) provides:

"An appeal to the Court of Appeals shall be conducted in the same manner as an appeal in an equity suit and shall be advanced on the court's docket in the same manner as appeals in criminal cases."
