The plaintiff had a verdict in this action of tort to recover for damage to the plaintiff’s dwelling house at 375 Broadway, Somerville, allegedly caused by negligent blasting by the defendant under a contract with the metropolitan district commission (the commission). The defendant excepted to the denial of its motion for a directed verdict, to the admission of evidence of an alleged expert on blasting called by the plaintiff,'and to the judge’s charge.
The jury could have found facts as follows: The .defendant, under the contract, was excavating a shaft ("Shaft 9”) to connect with a tunnel to be used to provide water for the
The plaintiff was in her home on March 16, 1953, at two o’clock in the afternoon when she heard “sort of a roar or rumble.” She was “jounced.” She heard falling objects downstairs. All of her canned goods in the pantry had fallen to the floor. Objects fell from a table and a vase toppled over. There were cracks in several ceilings and a. stairway was “slanted.” On March 17 before six o’clock in the morning she heard another “roar” which shook the house. There were similar occurrences on March 18 at about quarter of five in the afternoon but not thereafter. 1
The defendant’s daily blasting report showed that the defendant set off a blast of 180 pounds on March 16 at 2 p.m., no blast on March 17, a blast of 180 pounds on March 18 at 5:45 p.m., and a blast of 163 pounds on March 20. It showed also that beginning on March 23, all blasts were set off with the use of “delays,” that is, the total charge of powder was divided into several smaller charges, each of which was set off successively. Delays were not used in any of the blasts prior to March 23, but were used on April 3 when the pounds detonated were 172; on March 24 for 212 pounds; March 30, 200 pounds; April 4, 212 pounds; and April 11, 208 pounds. Other poundages after March 23 were larger.
The contract specifications required that “Blasting shall be done with explosives of such power and in such quantities and positions as will not . . . damage any existing structures. To this end, every blast in the shaft shall be exploded, by use of delays, in stages consistent with the location, type and character of the rock. . . . The contractor . . . will ... be held responsible for and shall make good any damage to other property whether or not owned by the commission.” The department of public safety rules and regulations form Y provides: “In blasting operations, no charge shall be used in any one blast which will result in
There was testimony that a single charge generates more earth movement than a series of delays. An expert for the defendant testified that “[T]t is usual and standard procedure to use delays in solid rock.”
The daily report shows progressive lower elevations from —12 feet on March 23 to —172 feet on May 9, 1953. The —12 figure means 12 feet below sea level which in the shaft was about 60 feet below the surface. The overburden was about 28 feet. The blasting was all in bedrock except to remove occasional large boulders in the overburden. Testimony that on March 23 the depth was 60 feet (or 63 feet as shown on the daily report) and the overburden was 28 feet, permitted the conclusion that the blasting had been in solid rock for some time. The daily record sheet shows that in rock the average increase in depth from blast to blast (with no blasting on some days) was about 6% feet. March 21 and 22, 1953, were respectively Saturday and Sunday. The jury could have concluded therefore that on March 16 and 18 (and on the 17th if there was a blast on that day) the defendant was blasting in solid rock. 1
The defendant admits that the testimony would warrant a finding of causation (see

v.
West Roxbury Trap Rock Co.
1. A majority of the court thinks there was evidence of negligence. The contract which in its requirement of delays made specific the provision of the rule for the use of small charges where necessary to avoid injury was of course not admissible to establish a duty to the plaintiff. In

Larkin,
The Judicial Council, in their Thirty-third Report (1957), Pub. Doc. No. 144, in commenting on a proposed act to provide “that the doctrine of res ipso loquitur shall be applicable in actions for damages caused by blasting or the keeping of explosives” said: “In these days blasting has become a public necessity — like the use of dangerous cars on the highways and safety rules are needed . . . .” We agree, and we rule, that the precautions required by the public agency causing the blasting to be done, in reasonable implementation of such rules, are some evidence of what due care requires.
The failure to take the care required in the circumstances is further evidenced by the testimony of the defendant’s expert, that “It is usual and standard procedure to use delays in solid rock.” This evidence makes the cases above cited directly applicable.
We need not appraise the evidence for possible “rational inferences”

2. The jury could have concluded that the plaintiff’s damage resulted from the defendant’s negligent failure to use delays. There was, it is true, no direct testimony to this effect. We disregard the testimony of the plaintiff’s witness Champa. His knowledge of blasting was confined to that acquired from practical experience in surface blasting and his testimony that “nothing would have happened if precautions had been taken ... I would have used lesser charges,” does not stand as that of an expert in the effect of blasting in subsurface bedrock. It is not apparent that

Notes
The plaintiff in answer to interrogatories had said that damage occurred on March 16, 1953, and various other dates over a two months’ period, but left it by her testimony at the trial that the damage occurred on three days and “might” have occurred later in the period.
There was testimony that the solid rock or ledge began at 60 feet below the surface, but this was before the witness corrected his first testimony that the overburden (“the material covering the rock’’) was about 60 feet in depth. He left it that the overburden was 28 feet.
The persuasive argument for strict liability for damage from concussion or vibration as well as from thrown debris is restated in the recent cases of
