To this rather naïve letter Durham on June 18th replied stating even more clearly that no act of his would diminish Arthur's influence and authority in Upper Canada. He goes on to put his case as follows,

"I repeat to you, that I have no wish to interfere with the local administration of the affairs of any of the provinces included in my general government.

"Those functions will be vested, as before, in the Lieutenant-Governors; but it is essential to the success of my mission and to the due execution of my duties, more especially in the present disturbed state of our relations with the frontier population of the United States, that I should be promptly and directly made acquainted with all events bearing on those important questions."

Arthur seems to have followed out Durham's instructions as regards frontier troubles to the letter, since we find the following postscript added to his despatch of June 22nd, 1838 (No. 4):

"P.S. I make now no communications myself to the American Government, and have troubled your Lordship with all these particulars, as a representation will of course come with far greater force from your Lordship."[[34]]

In July, 1838, Lord Durham made a flying visit to Upper Canada. His object seems to have been to ascertain for himself existing conditions in this province and to form his own opinion as to what policy it would be best to pursue. He writes thus to Lord Glenelg from Montreal on July 6th:

"Lower Canada is perfectly free from internal troubles, and her frontier is not menaced by the Americans; but Upper Canada, by the last accounts from Sir George Arthur, is in a very unsatisfactory state, both as to domestic dissensions and border incursions. I am anxious, therefore, to proceed there as soon as possible."[[35]]

Lord Durham left Montreal on July 10th, arrived in Kingston late on the night of the 11th, and then proceeded to Niagara. At Niagara Sir George Arthur met him. From Niagara Lord Durham journeyed to Toronto where Sir George was also present to receive him formally, along with the mayor and corporation and the citizens of the provincial capital. On the 19th of July Durham returned to Kingston and thence down the St. Lawrence to Montreal where he arrived on July 24th. His visit to Upper Canada had been short but he had covered a great deal of territory and seems to have been pleased with what he saw.

If one of Lord Durham's objects in making his hurried trip to Upper Canada was to obtain a better understanding with Sir George Arthur he must have been disappointed since shortly after his return to Lower Canada their relations became somewhat strained. The reason for this was the action of Sir George Arthur and his Executive Council in sentencing to death Samuel Chandler and Benjamin Waite for their part in the Short Hills affair. The families of these men had appealed to Durham "for an extension of the Royal mercy" and "for the grant to them of Her Majesty's pardon."[[36]] Durham asked Arthur for particulars, reminding him that Lord Glenelg had written on the 3rd of April asking that "the utmost lenity, compatible with public safety, should be exercised towards the insurgents."

To this Sir George Arthur replied on August 20th, complaining that Durham's action was "depriving the officer administering the Government of Upper Canada of the powers expressly vested in him by the Royal Commission."[[37]] Arthur also claimed that Durham "had misapprehended the intention of the instruction of the Secretary of State" and Lord Glenelg had in a despatch of July 12th referred him "to the power of pardoning for treason vested in the officers administering this government under your Lordship's commission as Governor-in-Chief."
