Corporation operating a system of dams and gates for conservation of water for benefit of lower riparian stockholders, but 
not owning the water, is not taxable under this section. 92 C. 38. Cited. 106 C. 580. Cited. 134 C. 299. History of statute 
discussed. 150 C. 578. Where plaintiff received seventy-five per cent of its gross earnings from furnishing steam for heat, 
this was its principal business and it was subject to the tax imposed by this section rather than to the corporate business 
tax on net income imposed by section 12-214. 151 C. 688. Where public utility water company which also sold produce 
and nursery stock claimed expenses of its orchard and nursery operations should be deducted from its gross earnings by 
virtue of a system of accounts prescribed by the public utilities commission, held that the statute may not be modified by 
a regulation of the commission and the company was not entitled to such deduction. 152 C. 674, 675. Amendments to 
uniform system of accounts after 1945 have no effect on tax base stated in this statute. 161 C. 145. "Gross earnings from 
operations" are all items contemplated by sections 600 through 615 of 1941 uniform system of accounts prescribed for 
electrical utilities and other receipts which fall under any of listed categories. Id. Since "transmission receipts" are not 
classified as "operating revenues" in the uniform system of accounts, or in any other accounts enumerated in this section, 
they are not taxable under chapter 212 of the general statutes. 169 C. 58. Cited. 202 C. 583.
