the terms of his contract of employment. It was admitted by counsel on both sides before us that it was difficult to find any one basis for the exceptions contained in the three clauses. It is clear however from clause (ii) that from the definition of the word "basic wages" certain earnings were excluded, though they must be earned by employees in accordance with the terms of the contract of employment. Having excluded "dearness allowance" from the definition of "basic wages", s. 6 then provides for inclusion of dearness allowance for purposes of contribution. But that is clearly the result of the specific provision in s. 6 which lays down that contribution shall be 61/4 per centum of the basic wages, dearness allowance and retaining allowance (if any). We must therefore try to discover some basis for the exclusion in clause (ii) as also the inclusion of dearness allowance and retaining allowance (for any) in s. 6. It seems that the basis of inclusion in s. 6 and exclusion in clause (ii) is that whatever is payable in all concerns and is earned by all permanent employees is included for the purpose, of contribution under s. 6, but whatever is not payable by all concerns or may not be earned by all employees of a concern is excluded for the purpose of contribution. Dearness allowance (for examples is payable in all concerns either as an addition to basic wages or as a part of consolidated wages where a concern does not have separate dearness allowance and basic wages. Similarly, retaining allowance is payable to all permanent employees in all seasonal factories like sugar factories and is therefore included in s. 6; but houserent allowance is not paid in many concerns and sometimes in the same concern it is paid to some employees but not to others, for the theory is that houserent is included in the payment of basic wages plus dearness allowance or consolidated wages. Therefore, houserent allowance which may not be payable to all employees of a concern and which is certainly not paid by all concern is taken out of the definition of "basic wages", even though the basis of payment of houserent allowance where it is paid is the contract of employment. Similarly, overtime allowance though it is generally in force in all concerns is not earned by all employees of a concern. It is also earned in accordance with the terms of the contract of employment; but because it may not be earned by all employees of a concern it is excluded from "basic wages". Similarly, commission or any other similar allowance is excluded from the definition of "basic wages" for commission and other allowances are not necessarily to be found in all concerns; nor are they necessarily earned by all employees of the same concern, though where they exist they are earned in accordance with the terms of the contract of employment. It seems therefore that the basis for the exclusion in clause (ii) of the exceptions in s. 2(b) is that all that is not earned in all concerns or by all employees of concern is excluded from basic wages. To this the
