[ULPIANUS libro singulari de officio curatoris rei publicae. ] §22.1.33.prSi bene collocatae sunt pecuniae publicae, in sortem inquietari debitores non debent et maxime, si parient usuras: si non parient, prospicere rei publicae securitati debet praeses prouinciae, dummodo non acerbum se exactorem nec contumeliosum praebeat, sed moderatum et cum efficacia benignum et cum instantia humanum: nam inter insolentiam incuriosam et diligentiam non ambitiosam multum interest.
[ULPIANUS libro singulari de officio curatoris rei publicae.] If public moneys are well invested, the debtors ought not to be disturbed for the principal, and especially so if they yield interest; if they do not yield interest, the governor of the province must look out for the security of the municipality, provided that he does not show himself to be a harsh or abusive collector, but moderate, kind with efficiency, and humane with persistence; for there is a great difference between careless insolence and unpretentious diligence.
§22.1.33.1Praeterea prospicere debet, ne pecuniae publicae credantur sine pignoribus idoneis uel hypothecis.
Furthermore, he must take care that public moneys are not lent without suitable pledges or mortgages.
