Having unlimited time at his disposal, and a good horse and buggy, this young gentleman has since that day devoted almost his whole time to the investigation, and the results were such as to decide him at once that the real estate business was by no means overcrowded, and he therefore took an offioe, and has commenced to handle Los Angelos dirt with a well-founded prospect of making much ooin by it. In the first place he noticed that from the window of hia room on Fort-street, and quite a limited view at that, he could count twenty-six buildings in the course of erection. Then taking the Courthouse as a centre point he started out in a new direction every day, until he had covered every foot of land inside the limits of the city, and then adding together the result of the figures he hai noted down, he gave the following total : — There were 1400 houses for whioh the contracts had been let and the buildings were then in the course of construction. Of this number rather more than a fair proportion are buildings of the better class and decidedly entitled to entry under the head of permanent improvements. There were contracts let and guarantees given on both sides, but in these cases the buildings were not commenced, for a number of buildings, which when com pleted will consist collectively of 12,000 rooms. This estimate does not include either of the mammoth hotels which are to be contracted for in all probability during the month of November, neither does it irclude any buildings except thos9 in which part of the money has been paid to the contractors or bonds given. About six weeks ago the enormous sum of 55,000,000 dollars was to have been paid inside the next three months for real estate, and of this sum in the six weefes which have expired from the time the figures were given, a little over 10,000,000 dollars has been paid over. Yet with all this money put in circulation, tbe banks of this city have in their vaults subject to check, rather more actual cash than they had tils, weeks ago.
