“All the said lands of Bourhope, with the houses, buildings, gardens, orchards, parts, pendicles, and pertinents whatsoever aforesaid, and then following these words (in page 261): “Una cum duobus lacubus nuncupat. lie St. Marie Lochis de Lowis cum solo terris piscariis et pertinen. earundem lacum cum potestate dicto Roberto Scott suisque antedict. dictos lacus aridandi et aliter eisdem utendi et de super disponendi tanquam ipsorum propriam hereditatem ad ipsorum arbitrium in futurum.”
“The presumption of the common law itself is in favour of the pursuer's demand. The principle, as stated by Lord Stair, is:—‘Albeit woods and lochs use oft to be expressed, yet they are comprehended under parts and pertinents; and therefore the master of the ground hath not only right to the water in lochs, but to the ground thereof, and may drain the same, unless servitudes be fixed to water gangs of mills, or other works; and the ground of the loch, and all that is upon it, or under it, is a part of the fee; but if the loch be not wholly within the fee, but partly within or adjacent to the fee of another, then unless the loch be expressed, it will be divided among the fiars whose lands front thereupon.’ Lord Bankton, under the head ‘parts and pertinents of the fee,’ states, that ‘if the loch is between two contiguous heritors, it belongs to them equally, unless it be provided otherways by the rights.’ Professor Bell states this principle thus: ‘Navigable lakes do not, generally speaking, appear to be inter regalia , as rivers are. If wholly within the lands of one proprietor, the lake goes as a pertinent of the land. If not so, but touching the estates of various proprietors, the lake and its solum rateably belongs to them all.’ And he elsewhere states that lakes which give a permanent source to rivers, are not to be drained by the owner of the ground in which they are situated.’”
“The lands of Bourhope, prior to 1607, belonged to Robert Lord Roxburgh.”
“Lady Napier requests, that gentlemen fishing in St. Mary's and the loch of the Lowes will have the goodness to abstain from the use of the lath. September 1st, 1835.”
“That Mr. Scott has, along with the other proprietors whose lands lie around, and border on the same, a joint right or common property in St. Mary's Loch, and the Loch of the Lowes, and a joint right of using boats, fowling, fishing, floating timber, and exercising all other rights in or over the said lochs, and that Lord Napier has no exclusive right either of property or of use in or over the said lochs or either of them, and that the defender Lord Napier should be decerned and ordained to desist and cease from molesting and interrupting the appellant in the exercise of any of the rights aforesaid, and further, that the appellant should be entitled to the expenses in the Court below, but that there should be no costs of this appeal, and that the cause be remitted to the Court of Session to do therein as should be just and consistent with this declaration and judgment.”
