age upon such improvement. When such assessment is to be made upon lots in proportion to their frontage upon the improvement, if from the shape or size of any lot an assessment thereon in proportion to its frontage would be unjust and disproportionate to the assessment upon other lots, the council or board of assessors making the assessment may assess such lot for such number of feet frontage as in their opinion will be just.”
Chapter 8 of said act prescribes the method of initiating such improvements and making special assessments therefor. Section 2837,1 Comp. Laws (3 How. Stat. [2d Ed.] § 6058), provides:

In Corliss v. Village of Highland Park, 132 Mich. 157 (93 N. W. 254, 610, 95 N. W. 416), it was held that prior to the enactment of said section 22 the law authorized but a single assessment, limited to 5 per cent, of the value of the property. In Corliss v. Village of Highland Park, 146 Mich. 597 (110 N. W. 45), it was held that an assessment made under added section 22, Act No. 39, Pub. Acts 1899, though payable in installments at the option of the owner, was, nevertheless, a single assessment, limited to
