[POMPONIUS libro quinto ad Sabinum. ] §7.1.19.prProculus putat insulam posse ita legari, ut ei seruitus imponatur, quae alteri insulae hereditariae debeatur, hoc modo: 'Si ille heredi meo promiserit per se non fore, quo altius ea aedificia tollantur, tum ei eorum aedificiorum usum fructum do lego' uel sic: 'Aedium illarum, quoad altius, quam uti nunc sunt, aedificatae non erunt, illi usum fructum do lego. ' §7.1.19.1Si arbores uento deiectas dominus non tollat, per quod incommodior is sit usus fructus uel iter, suis actionibus usufructuario cum eo experiundum.
[POMPONIUS in the fifth book on Sabinus.] Proculus thinks that a block of flats (insula) can be so bequeathed that a servitude is imposed on it which is owed to another block of flats belonging to the inheritance, in this manner: 'If he promises my heir that he will not do anything to prevent those buildings from being raised higher, then I give and bequeath the usufruct of those buildings to him,' or thus: 'I give and bequeath to him the usufruct of those buildings, as long as they are not built higher than they are now.' If the owner does not remove trees blown down by the wind, whereby the usufruct or the right of way becomes less convenient, the usufructuary must take legal action against him with his own remedies.
