                            August 26, 1999

Before KING, Chief Judge, and JOLLY and DAVIS, Circuit Judges.

PER CURIAM:*

         Allen Jerry Fields, Jr., federal inmate # 08388-035,

appeals the district court’s dismissal of his complaint filed on

May 26, 1998, as frivolous.     His motion for the appointment of

appellate counsel is DENIED.




     *
        Pursuant to 5TH CIR. R. 47.5, the court has determined
that this opinion should not be published and is not precedent
except under the limited circumstances set forth in 5TH CIR.
R. 47.5.4.

                                 -2-

     Fields alleged constitutional violations occurring on May 6,

1992.    Fields argues that his claims had not prescribed because

he filed his complaint within one year from the date on which he

discovered a case that led him to conclude that his rights had

been violated.    Fields asserts, correctly, that while state law

governs the prescriptive or limitations period, federal law

governs when the cause of action arises or accrues.     See Gartrell

v. Gaylor, 981 F.2d 254, 257 (5th Cir. 1993).     Under federal law,

a cause of action accrues “when the plaintiff is in possession of

the `critical facts that he has been hurt and who has inflicted

the injury,’” not when he discovers the legal basis of his claim.

Id. (citations omitted); see Piotrowski v. City of Houston, 51

F.3d 512, 516 (5th Cir. 1995) (“A plaintiff need not realize that

a legal cause of action exists; a plaintiff need only know the

facts that would support a claim.”).    Accordingly, the district

court did not abuse its discretion in determining that Fields’

claims are frivolous because they have prescribed.     See McCormick

v. Stalder, 105 F.3d 1059, 1061 (5th Cir. 1997).

     Fields also argues that the district court erred in denying

his motion for appointment of counsel.     The magistrate judge

denied the motion, and Fields did not appeal to the district

court.   See 28 U.S.C. § 636(b)(1).   This court lacks jurisdiction

to address the magistrate judge’s order denying Fields’ motion

for appointment of counsel.     See Colburn v. Bunge Towing, Inc.,

883 F.2d 372, 379 (5th Cir. 1989).

     AFFIRMED; MOTION DENIED.
