The Grand Lodge of England afterwards found it necessary to be more explicit on this subject, and the regulation of that body is now contained in the following language: "No candidate shall be permitted to receive more than one degree on the same day, nor shall a higher degree in Masonry be conferred on any Brother at a less interval than four weeks from his receiving a previous degree, nor until he has passed an examination in open lodge in that degree."[74] This seems to be the recognized principle on which the fraternity are, at this day, acting in this country. The rule is, perhaps, sometimes, and in some places, in abeyance. A few lodges, from an impolitic desire to increase their numerical strength, or rapidly to advance men of worldly wealth or influence to high stations in the Order, may infringe it, and neglect to demand of their candidates that suitable proficiency which ought to be, in Masonry, an essential recommendation to promotion; but the great doctrine that each degree should be well studied, and the candidate prove his proficiency in it by an examination, has been uniformly set forth by the Grand Lodge of the United States, whenever they have expressed an opinion on the subject. Thus, for instance, in 1845, the late Bro. A.A. Robertson, Grand Master of New York, gave utterance to the following opinion, in his annual address to the intelligent body over which he presided: "The practice of examining candidates in the prior degrees, before admission to the higher, in order to ascertain their proficiency, is gaining the favorable notice of Masters of lodges, and cannot be too highly valued, nor too strongly recommended to all lodges in this jurisdiction. It necessarily requires the novitiate to reflect upon the bearing of all that has been so far taught him, and consequently to impress upon his mind the beauty and utility of those sublime truths, which have been illustrated in the course of the ceremonies he has witnessed in his progress in the mystic art. In a word, it will be the means of making competent overseers of the work--and no candidate should be advanced, until he has satisfied the lodge, by such examination, that he has made the necessary proficiency in the lower degrees."[75] In 1845, the Grand Lodge of Iowa issued a circular to her subordinates, in which she gave the following admonition: "To guard against hasty and improper work, she prohibits a candidate from being advanced till he has made satisfactory proficiency in the preceding degrees, by informing himself of the lectures pertaining thereto; and to suffer a candidate to proceed who is ignorant in this essential particular, is calculated in a high degree to injure the institution and retard its usefulness."
