CUTTER, J.

Wilbur was employed by the Commonwealth as a "natural resource officer." See G.L.c. 21, §§ 1, 6, 6A-6E, as amended. He was convicted under nine separate indictments for breaking and entering summer dwellings in the Plymouth and Wareham area with intent to commit larceny and for larceny. The trial was conducted under G.L.c. 278, §§ 33A-33G, as amended. Wilbur appealed. Further facts are stated in connection with particular assignments of error.

1. Prior to trial Wilbur moved to suppress certain evidence obtained by searches which he claimed were "unreasonable and in violation of" his constitutional rights. At the hearing on the motion, the following facts were found.

Wilbur operated an antique shop known as the Witch's Brew in North Dartmouth, about thirty miles from his Page 378 house in Plymouth. On Sunday, March 21, 1965, Trooper Waterhouse of the State police requested Wilbur to go to the North Dartmouth State police barracks. Wilbur proceeded toward the barracks in his automobile followed by Waterhouse and another officer in a police vehicle. On the way, Waterhouse received a radio call from his superior, Lieutenant Harrington, asking that they meet him at the Witch's Brew. This request was relayed to Wilbur.

Several days earlier on two separate occasions two of the alleged victims of the thefts had visited the Witch's Brew, and, from the sidewalk through the glass front of the shop, had observed some property belonging to them. On this evidence, on March 19, 1965, Trooper Waterhouse obtained three search warrants (from the Third District Court of Bristol) authorizing a search of the Witch's Brew, and on March 20, 1965, obtained an arrest warrant for Wilbur from the Fourth District Court of Plymouth.

When Wilbur and Waterhouse arrived at the Witch's Brew, Lieutenant Harrington had these warrants in his possession and handed them to Wilbur. Lieutenant Harrington warned Wilbur of his right to counsel, his right to make a telephone call to counsel or friends, his right to remain silent, and that anything he said might be used against him in court. Lieutenant Harrington then asked Wilbur to admit them to the shop. Wilbur replied, "It's all right with me, but I don't have the key." Thereupon, Lieutenant Harrington went to a side door, which "was slightly ajar but wired from the inside with one strand of copper wire wound around a nail." He pushed open the door and, with other police officers, followed Wilbur inside.

Within one hour and one half after the defendant's arrest, the officers seized some of the allegedly stolen property. More stolen property was seized at the Witch's Brew during the months following Wilbur's arrest under additional search warrants obtained from the Third District Court of Bristol after other victims had identified property seen through the window of the store as belonging to them. Page 379

The judge who heard Wilbur's motion to suppress ruled among other things: (a) Wilbur was lawfully arrested at 10:30 A.M. on March 21, 1965, on the street immediately in front of the Witch's Brew. (b) The search of the Witch's Brew on March 21 and the seizure of stolen property described in the three warrants given by Lieutenant Harrington to Wilbur were incident to a lawful arrest. (c) All search warrants issued by the Third District Court of Bristol were defective because they lacked the teste of the first justice of that court.

Reasonable searches may be made without a warrant if incident to a lawful arrest. Commonwealth v. Holmes, 344 Mass. 524, 525-526. This arrest took place in the immediate vicinity of, and in front of, the Witch's Brew which exhibits show to be a small glass structure, little more than a shed. Its walls consisted chiefly of large windows such as are usual in a greenhouse. Much of the interior appears to have been visible from outside the building. The interior was not well secured. It seems probable that the searches were so close in place and time to Wilbur's arrest that they were incidental to it within the cases cited (fn. 3). This we need not decide for the evidence was admissible on another ground.

With respect to all the contents of this structure seized and admitted in evidence, search warrants had been issued by the Third District Court of Bristol. We are not bound by the reasons given for the ruling by the judge (see Randall Page 380 v. Peerless Motor Car Co. 212 Mass. 352, 384; Young v. Duncan, 218 Mass. 346, 351) who heard the motion to suppress. We think that he erred in ruling that these warrants were not valid because they lacked the teste of the first judge of the District Court. The searches were valid if made pursuant to a valid warrant.

The presence of the teste is directed by Part II, c. 6, art. 5, of the Constitution of the Commonwealth, if a search warrant is a "writ" as the term is used in art. 5. A more specific provision appears in G.L.c. 218, § 6 (as amended through St. 1964, c. 638; see later amendments through St. 1966, c. 699, § 6), which reads, in part, "Citations, orders of notice, writs, executions and all other processes issued by the clerk of the court shall bear the teste of the first justice thereof." The section deals primarily with the justices and special justices of such courts and their compensation. No provision for a teste appears in G.L.c. 276, §§ 1, 2, 2A, 2B, 2C (as amended or inserted by St. 1964, c. 557; see later amendment of § 2B by St. 1965, c. 384). Indeed, the form of warrant specified in § 2A omits any teste whatsoever.

We interpret both the constitutional provision (fn. 4) and c. 218, § 6, as directory only (see Liberty Mut. Ins. Co. v. Acting Commr. of Ins. 265 Mass. 23, 28-29; Monico's Case, 350 Mass. 183, 185-186) and not as a mandatory requirement, the absence of which destroys the validity of a warrant otherwise correctly issued. The teste relates to a matter of form and not of substance. As Chief Justice Parker said in Ripley v. Warren, 2 Pick. 592, 595, "[N]othing can be more precisely mere matter of form than the teste of a writ, although by some unaccountable means it was thought important enough to be provided for in the Page 381 constitution of the state. We all know that in practice it is considered wholly insignificant; for the name of the proper officer may be inserted after the writ has been issued by the clerk, a blank being left for that purpose; or the name, if printed, may be erased and another inserted by the party. . . ." In the Ripley case, the court (p. 596) treated the writ, "though originally defective," as agreed to by the then defendant who made no point of the matter until late in that litigation. The teste of a writ may be amended at any stage in a proceeding. Nash v. Brophy, 13 Met. 476, 478. See Austin v. Lamar Fire Ins. Co. 108 Mass. 338, 339-341 (clerk's signature omitted from writ). See also Commonwealth v. Boon, 2 Gray, 74, 75.

The record does not suggest that any interest of Wilbur was affected by the absence of the teste. If he had questioned the authenticity of the warrant on that account, when it was shown to him, it could have been amended on the spot in this insignificant respect, at least with authorization to do so from the clerk who issued it. Examination of the original warrants shows that they were adequately authenticated by the signature of the assistant clerk and by the impressed seal of the court.

The use of search warrants is desirable to protect important individual interests. They, however, and the affidavits upon which they are based, must be read "in a commonsense way rather than technically." United States v. Ventresca, 380 U.S. 102, 108-109, 111-112. See Commonwealth v. Rossetti, 349 Mass. 626, 632, n. 5; Commonwealth v. Cuddy, ante, 305, 308; United States v. Bowling, 351 F.2d 236, 237 (6th Cir.). We treat the absence of the teste as of no legal significance, especially in circumstances such as those before us where it is apparent that omission of the Page 382 teste was an inadvertence which occurred when the warrant blanks (then currently in use by the court) were printed.

2. The trial judge admitted evidence that, immediately after his arrest, Wilbur made statements which could be found to have constituted admissions. It is principally argued that Wilbur's constitutional rights were violated by some brief interrogation of, and short conversations with, Wilbur after his arrest, while he and the others were within the Witch's Brew on March 21, 1965, the day of the arrest. Principal reliance is placed on Miranda v. Arizona, 384 U.S. 436, 467-479, decided June 13, 1966. Wilbur's trial began on September 21, 1966. We assume (without deciding) that the principles formulated in the Miranda case may apply to this trial, even though such interrogation as there was took place long before the Miranda decision. Johnson v. New Jersey, 384 U.S. 719, 721. Cf. Commonwealth v. Morrissey, 351 Mass. 505, 508-512; Commonwealth v. Rogers, 351 Mass. 522, 528-531.

In the Miranda case, at p. 479, it was stated that a person arrested "must be warned prior to any questioning that he has the right to remain silent, that anything he says can be used against him in a court of law, that he has the right to the presence of an attorney, and that if he cannot afford an attorney one will be appointed for him prior to any questioning if he so desires." The judge who heard the motion to suppress found that Lieutenant Harrington warned Wilbur "of his right to counsel, and to telephone counsel or friends and that anything he might say might be used against him in court." He was told he could use a telephone in the police barracks nearby, for there was no Page 383 telephone in the shop. The only element of the Miranda case warning not given was "that if he . . . [could not] afford an attorney one . . . [would] be appointed for him."

We hold that this omission is not material here and that the warning was adequate. Wilbur was in the uniform of a natural resource officer employed by the Commonwealth. He admitted that he owned the Witch's Brew and had just sold its contents. There was no reasonable basis for suspecting that he was indigent and every affirmative indication that he was in a position to employ counsel if he wanted an attorney. He was a law enforcement officer who (see G.L.c. 21, § 6B, as amended through St. 1964, c. 524, § 2) could "exercise . . . all the authority of police officers and constables, except the service of civil process." He cannot be regarded as ignorant of the rights of a person under arrest. We think the warning principles announced in the Miranda case must be applied reasonably and with common sense and do not constitute an arid, ritualistic formula to be administered inflexibly. We assume that the principles are designed to achieve the substance of protection of defendants requiring protection and not to penalize (for minor and nonprejudicial failure to adhere to a precise formula) law enforcement officials intelligently attempting in good faith to afford arrested persons considerate treatment and due process of law. Particularly must this be so, when action which occurred before the Miranda decision (so that police officers could not anticipate what was later to be decided), is being considered in connection with a trial begun after that decision.

At least one other court considering the problem has reached a similar conclusion, where there plainly was no prejudicial effect from failure to inform a defendant that, if indigent, counsel would be appointed for him. State v. Gray, 268 N.C. 69, 80-83. We think that any incompleteness in the warning given to Wilbur was, on the facts in this Page 384 record, "harmless beyond a reasonable doubt." See Chapman v. California, 386 U.S. 18, 24.

3. The trial judge gave a full and accurate charge. Among other things, he instructed the jury that, where there is possession of stolen property by a defendant soon after a theft, and the possessor "offers no explanation as to his possession, there is a presumption that he stole it." Such possession, he said, "if no explanation is given, or an unsatisfactory account is given, is presumptive evidence of guilt." To this portion of the charge Wilbur's attorney made an objection which we assume to have been an exception, although it is by no means clear that an exception in fact was saved. This objection was not based upon the contention that the judge had "misstated the Massachusetts law on this subject" but on the ground that the charge violated the constitutional privilege "which enables a defendant to remain silent in the face of any accusation." The judge charged specifically that Wilbur had a constitutional privilege not to testify and that "the fact that Wilbur did not take the stand does not give you [the jury] the right to draw an unfavorable inference therefrom."

The charge concerning the presumption which arises from the unexplained possession of recently stolen goods was consistent with our cases. Commonwealth v. Grace, 265 Mass. 119, 123-124. Commonwealth v. Torrealba, 316 Mass. 24, 29. Commonwealth v. Brant, 346 Mass. 202, 205. Cf. Commonwealth v. Fancy, 349 Mass. 196, 200 (where it was not established that the defendant ever had any stolen property in his possession). Similar presumptions or permissible inferences were upheld in Yee Hem v. United States, 268 U.S. 178, 183-185, and United States v. Gainey, 380 U.S. 63, Page 385 65-68, 70-71. See Commonwealth v. Williams, 171 Mass. 461, 462-463. Cf. United States v. Romano, 382 U.S. 136, 139-144.

We do not view the charge as in any sense an improper comment on Wilbur's failure to testify in violation of art. 12 of Part I of the Constitution of the Commonwealth, or of G.L.c. 233, § 20, Third, provisions which long antedated the decision in Griffin v. California, 380 U.S. 609, 612-615. See Opinion of the Justices, 300 Mass. 620, 624-626. The presumption or inference of guilt arising from unexplained possession of recently stolen goods may be overcome by evidence other than that of the defendant. Indeed, facts proved by the prosecution may be sufficient to overcome the presumption or to preclude any adverse inference. A proper and reasonable charge, like the charge before us, concerning the principle cannot be distorted into forbidden comment on a defendant's failure to take the stand. The pertinent authorities are comprehensively discussed in Anglin v. State, 244 Md. 652, 656-663.

Judgments affirmed.
